decnet path-split-mode

To specify how the Cisco IOS software splits the routable packets between equal-cost paths, use the decnet path-split-mode command with the appropriate keyword in global configuration mode.

decnet path-split-mode {normal | interim}

Syntax Description

normal

Normal mode, where equal-cost paths are selected on a round-robin basis. This is the default.

interim

Traffic for any particular (higher-layer) session is always routed over the same path. This mode supports older implementations of DECnet (VMS Versions 4.5 and earlier) that do not support out-of-order packet caching. Other sessions may take another path, thus using equal-cost paths that a router may have for a particular destination.

normal	Normal mode, where equal-cost paths are selected on a round-robin basis. This is the default.

Usage Guidelines

By default, Cisco's DECnet routing software implements fast switching of DECnet datagrams. There are times when it makes sense to disable fast switching. This is especially important when using rates slower than T1.

Fast switching uses memory space on interface cards. In situations where a high-bandwidth interface is writing large amounts of information to a low-bandwidth interface, additional memory could help avoid congestion on the slow interface.

Examples

The following example disables fast switching on Ethernet interface 0:

interface ethernet 0

Usage Guidelines

The designated router is the router to which all end nodes on an Ethernet communicate if they do not know where else to send a packet. The designated router is chosen through an election process in which the router with the highest priority gets the job. When two or more routers on a single Ethernet in a single area share the same highest priority, the unit with the highest node number is elected. You can reset a router's priority to help ensure that it is elected designated router in its area.

On a LAN with both DECnet IV and DECnet IV Prime hosts, make sure that a bilingual router always becomes the designated router.

DECnet end systems use the designated router only when they have no other information about how to reach a particular system. The end systems maintain a cache of how to reach other systems on the network. The cache contains the following information:

<remote system DECnet address>  <next hop DECnet address>

When an end system receives a packet, it examines three pieces of information: the intra-LAN bit, the source address, and the previous hop. If the intra-LAN bit is set, indicating that the packet has never left this wire (and, thus, the remote system is reachable without a router), a cache entry is created as follows:

<remote system DECnet address> = <source address>
<next hop DECnet address> = <source address>

If the intra-LAN bit is not set, indicating that the packet has come from another network, the cache entry is created as follows:

<remote system DECnet address> = <source address>
<next hop DECnet address> = <previous hop>

If there is no cache entry, then the designated router is used. This means that when starting a session, the designated router is used, but the reverse traffic will populate a cache entry so that the router can later communicate directly.

A DECnet IV Prime end node sends a packet to the Unknown Destination multicast if it has no cache entry for the destination and has no designated router.

Examples

The following example sets DECnet priority for this router to 110 on Ethernet interface 1:

interface ethernet 1
 decnet router-priority 110

Usage Guidelines

Enabling DECnet changes the MAC addresses of the router's interfaces. This is not a problem on routers equipped with nonvolatile memory. On systems that attempt to get their IP network addresses from network servers rather than from nonvolatile memory, there may be a problem as with the hardware addresses changing and confusing other IP-speaking hosts. This potential problem can be avoided by configuring and enabling DECnet before enabling other protocols.

Note You can configure up to four DECnet networks (numbered 0 to 3). To set up multiple DECnet networks, use the decnet global configuration commands with the appropriate network number and keywords. If the network number is omitted from the commands, network 0 is configured for DECnet routing.

DECnet Phase IV Prime eliminates the DEC addressing restrictions so that DECnet nodes can coexist with systems running other protocols that have other MAC address restrictions. If iv-prime is not specified, only Phase IV is enabled; configuring the MAC address will then make DECnet inoperable. The standard "AA-00-04-00" form will be set as the address of the interface on which DECnet is enabled. If Phase IV Prime was already running and this command is reissued without the iv-prime keyword (that is, going from Phase IV Prime to Phase IV), the command returns an error if any of the interfaces that have DECnet enabled have MAC addresses that are not compliant with DECnet Phase IV, requiring the user to evaluate conflicting interface commands.

The no form of this command disables Phase IV and Phase IV Prime routing.

The following example enables DECnet routing for the router in area 21 with node number 456:

decnet routing 21.456

Usage Guidelines

Other routers use this information to construct local routing tables. In a network where changes occur infrequently or do not need to be responded to immediately (it is small and uncomplicated, applications are not particularly sensitive to delays or occasional packet loss, slow serial links, and so on), increasing the time between routing updates reduces the amount of unnecessary network traffic. Digital calls this argument the broadcast routing timer because they use a different timer for serial lines; Cisco's DECnet implementation does not make this distinction.

Examples

The following example sets a serial interface to broadcast routing updates every 2 minutes (120 seconds):

interface serial 0
 decnet routing-timer 120

decnet split-horizon

To use split horizon when sending routing updates, use the decnet split-horizon command in interface configuration mode. To disable split horizon, use the no form of this command.

Command Modes

Usage Guidelines

The decnet split-horizon command also affects whether broadcast packets received on an interface are resent on the same interface.

The decnet split-horizon command determines how much information is included in routing updates sent out an interface. It also determines whether received broadcasts are retransmitted on the same interface. When you enable split horizon, routing updates sent out on a given interface will not include any information that was originally learned from that interface, and broadcasts will not be retransmitted on the receiving interface. This is because split horizon is designed for networks that are either broadcast networks, or are fully connected mesh networks. In these types of networks, resending this information is a waste of network bandwidth because all other stations on that network have already heard the information. Disabling split horizon causes the Cisco IOS software to include all information in routing updates, and to resend broadcast packets on the network from which they were received.

You can use this command on any interface, but generally it makes sense to use it only for X.25 and Frame Relay interfaces. You should disable split horizon on X.25 and Frame Relay networks that are not fully connected mesh topologies.

Examples

The following example disables split horizon on an X.25 network:

interface serial 0

As the display shows, the show decnet route command can display more than one route for a destination when equal-cost paths have been set with the decnet max-paths global configuration command, and when there is more than one equal-cost path to a destination. The display also shows that this node is an area router.

Table 28 describes significant fields shown in the display.

Table 28: show decnet route Field Descriptions

Field Description

*

Currently selected route for a particular destination. In interim mode, the selected route will never appear to change.

Node

DECnet address of this (reachable) destination.

(Area)

All Level 1 routes are displayed in this section except for this the first entry, which points to the nearest Level 2 router.

Cost

Assigned cost for the interface, based on a recommended value for the underlying media. Range: 1 to 63. No default.

Hops

Number of hops to this node from the router being monitored.

Next Hop to Node

DECnet address of the next hop a packet will take to get to the final destination as well as the interface.

(Local)

The address that the router is configured with.

(OSI)

Indicates that this route is an OSI injected route - that is it comes from CLNS due to DECnet phase IV/DECnet phase V conversion.

(STATIC)

Indicates that this entry was created by the decnet route command.

Expires

Displays how many seconds from now this entry expires.

Prio

Router priority of this node.

V

Adjacent Level 1 router.

A+

Command History

Release Modification

This command was introduced.

Usage Guidelines

All static routes are stored in a static route queue, which allows static routes to be reinstated when DECnet routing is turned off then on again.

Not all routes in the static route queue will show up in the routing table. This happens under the following conditions:

The router is a Level 1 router and any of the following apply. Assume the router DECnet address is 1.1:
- A Level 2 area static route is configured.

A static route is configured not in the same area as the router.

decnet route 3.10 1.200

A static route is configured for the same address as the router.

decnet route 1.1 1.200

The router is a Level 2 router and any of the following apply. Assume the router DECnet address is 2.1:
- A Level 1 static router is not in the same area as the router.

A static route appears because a Level 2 route is installed to area 4.

decnet route 4.0 10.200

A Level 2 static route is configured for the router's own area.

decnet route 2.0 10.200

A static route is configured for the same address as the router.

decnet route 2.1 5.4

Examples

The following is sample output from the show decnet static command:

router# show decnet static
 
Address      Cost     Hops    Next hop          SNPA
 
 3             0       0      Ethernet0  aa00.0400.0404
 5             0       0      Serial0
 5.100         0       0      Serial2
 DEFAULT       0       0        2.100
 6             5       4        2.3

Note that this router is a Level 2 router with DECnet address of 1.2, so a static route configured for 5.100 is not relevant here. This route appears in the show decnet static command display, but not in the routing table.

show decnet traffic

    0 no memory

Records transaction attempts when the system has run out of memory.

    0 no routing vector

    0 congestion     encountered

Number of times the DECnet output process encounters a non-empty interface output queue.

HELLOs:

Displays the number of hello messages received and sent.

    received

Displays the total number of noncontrol (data) packets received.

    not long format

Displays the number of packets received which are not in the long DECnet format. This number should always be zero. If it is not, investigate the source of the improperly formatted packets.

    too many visits

Lists the number of packets received which have visited too many routers and have been flushed.

    forwarded

Lists the total number of packets forwarded.

    returned

Lists the total number of packets returned to the sender at the senders' request.

    converted

Displays the number of Phase IV packets converted to Phase V packets.

    local destination

Packets received that are destined for this router.

    access control failed

Lists the packets dropped because access control required it.

    no route

Lists the total packets dropped because the router did not know where to forward them.

    encapsulation failed

Lists the number of packets that could not be encapsulated. This usually happens where there are entries missing in a map for a public data network, such as X.25 or Frame Relay. This can also occur if an interface is set for an encapsulation for which there is no defined DECnet encapsulation, such as Point-to-Point Protocol (PPP) on serial interfaces.

    inactive network

Displays the number of packets that appear to come from a known interface, or that ATG returned because they did not make sense.

    incomplete map

Counts the number of packets that failed address translation. This usually means a node that is not in the ATG map is trying to access a node in another network advertised by the ATG.

0 unimplemented	Reports the number of incoming packets that are DECnet control packets, and how many specify a service that the router does not implement. This includes services implemented to forward Level 1 and Level 2 routing information, and router and end-system hello packets.
0 not a gateway	Reports the total number of packets received while not routing DECnet.
0 no memory	Records transaction attempts when the system has run out of memory.
0 no routing vector	Indicates that either a routing update came in from another router when the router did not have an adjacency for it, or it had no routing vector for the type of routing update. Use the debug decnet-routing EXEC command for more information.
0 congestion encountered	Number of times the DECnet output process encounters a non-empty interface output queue.
HELLOs:	Displays the number of hello messages received and sent.
received	Displays the total number of hello messages received. All protocol types are included.
bad	Displays the total number of "bad" hello messages received. Invoke the EXEC command debug decnet to display more information about why the hello message was judged as bad.
other area	Displays the total number of hello messages received from nodes on other areas when the router is a Level 1 router only.
sent	Displays the total number of hello messages sent.
Level 1 routing:	Displays the Level 1 routing updates received and sent.
received	Displays the total number of Level 1 routing updates received.
bad	Displays the total number of Level 1 updates received that were judged to be bad.
other area	Displays the total number of Level 1 updates from nodes in other areas.
sent	Displays the total number of Level 1 updates sent.
Level 2 routing:	Displays the Level 2 routing updates received and sent.
received	Displays the total number of Level 2 updates received.
not primary router	Should always be zero.
sent	Displays the total number of Level 2 updates sent.
Data:	Displays the number of data packets received and sent.
received	Displays the total number of noncontrol (data) packets received.
not long format	Displays the number of packets received which are not in the long DECnet format. This number should always be zero. If it is not, investigate the source of the improperly formatted packets.
too many visits	Lists the number of packets received which have visited too many routers and have been flushed.
forwarded	Lists the total number of packets forwarded.
returned	Lists the total number of packets returned to the sender at the senders' request.
converted	Displays the number of Phase IV packets converted to Phase V packets.
local destination	Packets received that are destined for this router.
access control failed	Lists the packets dropped because access control required it.
no route	Lists the total packets dropped because the router did not know where to forward them.
encapsulation failed	Lists the number of packets that could not be encapsulated. This usually happens where there are entries missing in a map for a public data network, such as X.25 or Frame Relay. This can also occur if an interface is set for an encapsulation for which there is no defined DECnet encapsulation, such as Point-to-Point Protocol (PPP) on serial interfaces.
inactive network	Displays the number of packets that appear to come from a known interface, or that ATG returned because they did not make sense.
incomplete map	Counts the number of packets that failed address translation. This usually means a node that is not in the ATG map is trying to access a node in another network advertised by the ATG.
