| Field | Description |
|---|---|
Codes: | Codes defining how the route was learned. |
R - RTMP derived | Route learned from an RTMP update. |
E - EIGRP derived | Route learned from an Enhanced IGRP update. |
C - Connected | Directly connected network. |
A - AURP | Route learned from an AURP update. |
S - Static | Statically defined route. |
P - Proxy | Proxy route. Proxy routes are included in outgoing RTMP updates as if they were directly connected routes (although they are not really directly connected), since they are not associated with any interface. Whenever an NBQ BrRq for the zone in question is generated by anyone anywhere in the internetwork, an NBP FwdReq is directed to any router connected to the proxy route. The Phase 2 router (which is the only router directly connected) converts the FwdReq to LkUps, which are understood by Phase 1 routers, and sends them to every network in the zone. |
routes | Number of routes in the table. |
Net | Network to which the route goes. |
Net 999-999 | Cable range to which the route goes. |
directly connected | Indicates that the network is directly connected to the router. |
uses | Fair estimate of the number of times a route gets used. It actually indicates the number of times the route has been selected for use prior to operations such as access list filtering. |
Ethernet | Possible interface through which updates to the remote network will be sent. |
zone | Name of zone of which the destination network is a member. |
[1/G] | Number of hops to this network, followed by the state of the link to that network. The state can be one of the following letters:
The state is determined from the routing updates that occur at 10-second intervals. A separate and nonsynchronized event occurs at 20-second intervals, checking and flushing the ratings for particular routes that have not been updated. For each 20-second period that passes with no new routing information, a rating changes from G to S and then from S to B. After 1 minute with no updates, that route is flushed. Every time the Cisco IOS software receives a useful update, the status of the route in question is reset to G. Useful updates are those advertising a route that is as good or better than the one currently in the table. When an AppleTalk route is poisoned by another router, its metric gets changed to poisoned (that is, 31 hops). The software then will age this route normally during a holddown period, during which the route will still be visible in the routing table. |
via 258.179 | Address of a router that is the next hop to the remote network. |
via gatekeeper | Node name of a router that is the next hop to the remote network. |
sec | Number of seconds that have elapsed since an RMTP update about this network was last received. |
The following is sample output from the show appletalk route command when you specify a network number:
Router# show appletalk route 69 Codes: R - RTMP derived, E - EIGRP derived, C - connected, A - AURP

S - Static | Static route. |
routes in internet | Number of routes in the Apple Talk internet. |
Net | Cable range to which the route goes. This is the number of the network you specified on the show appletalk route command line. |
[2/G] | Number of hops to this network, followed by the state of the link to that network. The state can be one of the following letters:
The state is determined from the routing updates that occur at 10-second intervals.

Usage Guidelines
If no zone name is specified, the command displays all entries in the zone information table.
You can use this command on extended and nonextended networks.
A zone name can be associated with multiple network addresses or cable ranges, or both. There is not a one-to-one correspondence between a zone name and a LAN; a zone name may correspond to one or more networks (LANs or network interfaces). This means that a zone name will effectively replace multiple network addresses in zone filtering. This is reflected in the output of the show appletalk zone command. For example, the zone named Mt. View 1 in the following example is associated with two network numbers and four cable ranges.

Usage Guidelines
The SMRP forwarding table describes the relationship between the SMRP router and the distribution tree for each SMRP group on the internetwork. An SMRP router has an entry in this table for every SMRP group for which the router is forwarding data. When data for an SMRP group arrives on the parent interface, it is forwarded to each child interface.
Looking at child and parent interfaces in relation to members of an SMRP group, a child interface is a neighbor that is farther away from the SMRP creator node and a parent interface is one that is closer to the creator node.
If no SMRP group address is specified, then the show smrp forward command displays information for all entries in the SMRP forwarding table. For all entries, the show smrp forward command displays the SMRP group address, the state of the SMRP group, the parent interface and address, and one or more child interfaces and addresses.
If an SMRP group address is specified, the command displays additional information for that group showing the child count, the time elapsed since the entry was updated, and the next poll time.
 |
Note Because SMRP is currently supported over AppleTalk networks only, sample output resulting from the show smrp forward command is the same as output from the show smrp forward appletalk command. |

Usage Guidelines
An SMRP router has an entry in its forwarding table for every SMRP group for which the router forwards data. For each group, the forwarding table lists the parent interface and address and one or more child interfaces and addresses. When data for an SMRP group arrives on the parent interface, the router forwards it to each child interface. The SMRP fast-switching cache table specifies whether or not to fast switch SMRP data packets out the interfaces specified by the forwarding table.
Use show smrp mcache command to view the SMRP fast-switching cache table. The command displays which interfaces are fast-switch enabled. If a parent interface is not fast-switch enabled, then there is no entry (row) in the table. If a child interface is not fast-switch enabled, then it is not in the list of child interfaces for an entry in the table.
If you do not specify an SMRP group address, then the show smrp mcache command displays information for all entries in the SMRP fast-switching cache table. If you specify an SMRP group address, the command displays cache entries for only that group.
SMRP fast-switching is enabled by default.

Usage Guidelines
By default, fast-switching is enabled on all SMRP ports. A network protocol and interface comprise an SMRP port. Fast switching improves the throughput rate by processing incoming packets more quickly than process switching.
SMRP uses the forwarding table to forward packets for a particular SMRP group. For each group, the forwarding table lists the parent interface and address and one or more child interfaces and addresses. When data for an SMRP group arrives on the parent interface, the router forwards it to each child interface. The SMRP fast-switching cache table specifies whether to fast switch SMRP data packets out the interfaces specified by the forwarding table.
SMRP fast switching requires that:
When the parent port is fast-switch enabled, the system populates and validates a fast-switching cache table when forwarding packets out child ports.
To populate the fast-switching cache table with fast-switching information, the first packets are process switched. Thus, the fast-switching cache table is populated with information about fast-switch enabled child ports. When succeeding packets arrive, the system uses the SMRP fast-switching cache table to fast switch the packets out those child ports.
If there are non-fast-switching ports in the forwarding table, then the system process switches the packet out those ports.
To validate the fast-switching cache table, the system validates each cache entry when it forwards the first packet out all child ports. If a cache entry is validated, the router can use the entry to fast switch succeeding packets out the child ports.
If a cache entry is invalidated, the router cannot use the entry to fast switch packets. The entry is removed from the fast-switching cache table and the router process switches packets out the child ports. A cache entry is invalidated when one of these conditions is met:
Examples
The following example disables SMRP fast-switching:
no smrp mroute-cache protocol appletalk
To make SMRP multicast services available over AppleTalk for a specific interface, use the smrp protocol appletalk command in interface configuration mode. To disable SMRP over AppleTalk for a specific interface, use the no form of the command.
smrp protocol appletalk [network-range beginning-end]
Syntax Description
network-range (Optional) SMRP network range for the interface. We recommend that you do not specify an SMRP network range. When you omit the range, the Cisco IOS software uses the AppleTalk cable range configured for the interface as the SMRP network range. If you specify a range, it must fall within the SMRP network range 1 to 65535. beginning-end (Optional) The beginning and end of the SMRP network range for this AppleTalk network. If you specify a range, it must fall within the SMRP network range 1 to 65535.
Defaults
SMRP is disabled.

Usage Guidelines
SMRP supports point-to-multipoint multicasting of packets for AppleTalk networks. This support provides the capability of sending data from a single source to multiple stations without having to send duplicate copies of the data.
The smrp protocol appletalk command configures SMRP support over an AppleTalk network on an interface basis. Before you use this command, you must issue the smrp routing command to enable SMRP. After you enable SMRP, you can use this command to make SMRP services available over AppleTalk for any number of individual interfaces.
We recommend that you do not specify an SMRP network range for the AppleTalk network. Because the upper limit of the AppleTalk network range is 65,535, AppleTalk network numbers always fit within the SMRP network range; SMRP network numbers are 3 bytes long, whereas AppleTalk network numbers are 2 bytes long. If the AppleTalk network is a nonextended network, which is defined by a single network number, the AppleTalk network is mapped to the SMRP network range using the single number to define both ends of the range (for example, 65,520-65,520).
To disable SMRP services for a specific AppleTalk network, use the no form of this command. To disable SMRP services globally (that is, for all AppleTalk networks whose interfaces you have configured for SMRP support) issue the no smrp routing command.
Examples
The following example enables SMRP globally and turns on SMRP support over AppleTalk for the current interface:
smrp routing
interface ethernet 0
smrp protocol appletalk
The following example disables SMRP over AppleTalk for the current interface:
interface ethernet 0
no smrp protocol appletalk

Usage Guidelines
Currently, SMRP services are supported over AppleTalk only. The smrp routing command enables the use of SMRP. To enable SMRP for an AppleTalk network over a specific interface, you must use the smrp protocol appletalk interface configuration command after you issue this command. The smrp routing command has no effect until you enable SMRP at the interface level.
Examples
The following example enables SMRP:

Use the test appletalk command to enter test mode. From test mode you can test the NBP protocol.
The following display shows how to enter Appletalk test mode:
Router# test appletalk
Router(atalk test)#
Type ? to display the following list of test options:
Router(atalk test)# ?
end Exit AppleTalk test mode
nbp AppleTalk NBP test commands
Type nbp ? to learn what NBP test commands you can use:
Router(atalk test)# nbp ? nbp confirm: send out an NBP confirm packet to the specified entity nbp lookup: lookup an NVE. prompt for name, type and zone nbp parameters: display/change lookup parms (ntimes, ncecs, interval) nbp poll: for every zone, lookup all devices, using default ?: print command list end: exit nbptest
The following list summarizes the nbp test commands you can use:
The remainder of this section shows and explains the syntax and output of the various NBP test commands.
When running any of the NBP tests, you specify a nonprinting character by entering a three-character string that is the hexadecimal equivalent of the character. For example, type :c5 to specify the test appletalk truncation wildcard.
This is the syntax of the nbp confirm command:
nbp confirm appletalk-address [:skt] object:type@zoneThe syntax description is as follows:
appletalk-address | AppleTalk network address in the form network.node. The argument network is the 16-bit network number in the range 1 to 65,279. The argument node is the 8-bit node number in the range 0 to 254. Both numbers are decimal. |
:skt | (Optional) Name of socket. |
object:type | Name of device and the type of service. The colon (:) between object and type is required. |
@zone | Name of the AppleTalk zone where the entity object:type resides. |
Examples
The following is sample output of the nbp confirm command. In this example, the test sends a confirm packet to the entity ciscoRouter in zone Engineering.
Router(atalk test)# nbp confirm 24279.173 my-mac:AFPServer@Engineering confirmed my-mac:AFPServer@Engineering at 24279n,173a,250s
This is the syntax of the nbp lookup command:
nbp lookup object:type@zoneThe syntax description is as follows:
object:type | Name of device and the type of service. The colon (:) between object and type is required. |
@zone | Name of the AppleTalk zone where the entity object:type resides. |
The following is sample output of the nbp lookup command:
Router(atalk test)# nbp lookup =:macintosh:c5@engineering (100n,50a,253s)[1]: `userA:Macintosh IIcx@engineering' (100n,16a,251s)[1]: `userB:Macintosh II@engineering' (200n,24a,253s)[1]: `userC:Macintosh IIci@engineering' (200n,36a,251s)[1]: `userD:Macintosh II@engineering' (300n,21a,252s)[1]: `userE:Macintosh SE/30@engineering' test appletalk lookup request timed out Processed 6 replies, 7 events
