To display the contents of the IP multicast routing table, use the show ip mroute command in EXEC mode.
show ip mroute [group-name | group-address] [source] [summary] [count] [active kbps]
Syntax Description
group-name | group-address (Optional) IP address, name, or interface of the multicast group as defined in the DNS hosts table. source (Optional) IP address or name of a multicast source. summary (Optional) Displays a one-line, abbreviated summary of each entry in the IP multicast routing table. count (Optional) Displays statistics about the group and source, including number of packets, packets per second, average packet size, and bits per second. active kbps (Optional) Displays the rate that active sources are sending to multicast groups. Active sources are those sending at a rate of kbps or higher. The kbps argument defaults to 4 kilobits per second (kbps).
Defaults
The show ip mroute command displays all groups and sources.
The show ip mroute active command displays all sources sending at a rate greater than or equal to 4 kbps.

Usage Guidelines
If you omit all optional arguments and keywords, the show ip mroute command displays all entries in the IP multicast routing table.
The Cisco IOS software populates the multicast routing table by creating source, group (S,G) entries from star, group (*,G) entries. The star (*) refers to all source addresses, the "S" refers to a single source address, and the "G" is the destination multicast group address. In creating (S,G) entries, the software uses the best path to that destination group found in the unicast routing table (that is, through Reverse Path Forwarding [RPF]).
Examples
The following is sample output from the show ip mroute command for a router operating in dense mode. This command displays the contents of the IP multicast routing table for the multicast group named cbone-audio.

S - Sparse | Entry is operating in sparse mode. |
C - Connected | A member of the multicast group is present on the directly connected interface. |
L - Local | The router itself is a member of the multicast group. |
P - Pruned | Route has been pruned. The Cisco IOS software keeps this information in case a downstream member wants to join the source. |
R - Rp-bit set | Indicates that the (S,G) entry is pointing toward the rendezvous point (RP). The RP is typically a prune state along the shared tree for a particular source. |
F - Register flag | Indicates that the software is registering for a multicast source. |
T - SPT-bit set | Indicates that packets have been received on the shortest path source tree. |
J - Join SPT |
|
H - Hardware switched | Indicates the outgoing interface is hardware switched because IP multicast MLS is enabled. |
Timers: | Uptime/Expires. |
Interface state: | Interface, Next-Hop or VCD, State/Mode. |
(*, 224.0.255.1) | Entry in the IP multicast routing table. The entry consists of the IP address of the source router followed by the IP address of the multicast group. An asterisk (*) in place of the source router indicates all sources. Entries in the first format are referred to as (*,G) or "star comma G" entries. Entries in the second format are referred to as (S,G) or "S comma G" entries. (*,G) entries are used to build (S,G) entries. |
uptime | How long in hours, minutes, and seconds the entry has been in the IP multicast routing table. |
expires | How long in hours, minutes, and seconds until the entry will be removed from the IP multicast routing table on the outgoing interface. |
RP | Address of the rendezvous point (RP) router. For routers and access servers operating in sparse mode, this address is always 0.0.0.0. |
flags: | Information about the entry. |
Incoming interface: | Expected interface for a multicast packet from the source. If the packet is not received on this interface, it is discarded. |
RPF neighbor | IP address of the upstream router to the source. "Tunneling" indicates that this router is sending data to the RP encapsulated in Register packets. The hexadecimal number in parentheses indicates to which RP it is registering. Each bit indicates a different RP if multiple RPs per group are used. |
Dvmrp or Mroute | Indicates whether the RPF information is obtained from the DVMRP routing table or the static mroutes configuration. |
Outgoing interface list: | Interfaces through which packets will be forwarded. When the ip pim nbma-mode command is enabled on the interface, the IP address of the PIM neighbor is also displayed. |
Ethernet0 | Name and number of the outgoing interface. |
Next hop or VCD | Next hop specifies downstream neighbor's IP address. VCD is the virtual circuit descriptor number. VCD0 means the group is using the static-map virtual circuit. |
Forward/Dense | Indicates that packets will be forwarded on the interface if there are no restrictions due to access lists or TTL threshold. Following the slash (/) is the mode in which the interface is operating (dense or sparse). |
Forward/Sparse | Sparse mode interface is in forward mode. |
time/time | Per interface, how long in hours, minutes, and seconds the entry has been in the IP multicast routing table. Following the slash (/) is how long in hours, minutes, and seconds until the entry will be removed from the IP multicast routing table. |

Usage Guidelines
The goal of the loop prevention algorithm is that traffic should not be sent down the tunnel if there is a possibility that, after leaving the tunnel, steady state routing will route the traffic back to the head of the tunnel.
The strategy of the loop prevention algorithm is to compare the Layer 3 routing distance to the egress from the tunnel tailend and tunnel headend. The loop check passes only if the tunnel tail is closer to the egress than the tunnel head is.
The loop prevention algorithm allows you to use the tunnel for a route if one the following cases applies:
The loop prevention algorithm prevents you from using the tunnel for a given egress in all other cases; in particular, when
Devices request metrics via a LDP adjacency. The display output shows detailed metric information.
The metric information includes a metric type (shown as routing_protocol/routing_protocol_subtype) and a metric value.
The routing protocol is as follows:
OSPF

Table 44 lists the fields displayed in this example.
| Field | Description |
LSPID | The LSP identifier. The first six octets form the System ID of the router that originated the LSP. The next octet is the pseudonode ID. When this byte is zero, the LSP describes links from the system. When it is nonzero,the LSP is a so called non-pseudonode LSP. This is similar to a router LSA in OSPF. The LSP will describe the state of the originating router. For each LAN, the designated router for that LAN will create and flood a pseudonode LSP, describing all systems attached to that LAN. The last octet is the LSP number. If there is more data than can fit in a single LSP, the LSP will be divided into multiple LSP fragments. Each fragment will have a different LSP number. An asterisk (*) indicates that the LSP was originated by the system on which this command is issued. |
LSP Seq Num | Sequence number for the LSP that allows other systems to determine if they have received the latest information from the source. |
LSP Checksum | Checksum of the entire LSP packet. |
LSP Holdtime | Amount of time the LSP remains valid, in seconds. An LSP holdtime of zero indicates that this LSP was purged and is being removed from all routers' LSDB. The value between brackets indicates how long the purged LSP will stay in the LSDB before being completely removed. |
ATT | The Attach bit. This bit indicates that the router is also a Level 2 router, and it can reach other areas. L1-only routers and L1L2 routers that have lost connection to other L2 routers will use the attached bit to find the closest L2 router. They will point a default route to the closest L2 router. |
P | The P bit. Detects if the IS is area partition repair capable. Cisco and other vendors do not support area partition repair. |
OL | The Overload bit. Determines if the IS is congested. If the Overload bit is set, other routers will not use this system as a transit router when calculating routers. Only packets for destinations directly connected to the overloaded router will be sent to this router. |
Area Address | Reachable area addresses from the router. For L1 LSPs, these are the area addresses configured manually on the originating router. For L2 LSPs, these are all the area addresses for the area to which this route belongs. |
IP Address | IPv4 address for the interface. |
Metric | IS-IS metric for the cost of the adjacency between the originating router and the advertised neighbor, or the metric of the cost to get from the advertising router to the advertised destination (which can be an IP address, an ES or a CLNS prefix). |
Affinity | Attribute flags of the link being flooded. |
Physical BW | Bandwidth capacity (in bits per second) of the link. |
Reservable BW | Amount of reservable bandwidth on this link. |
BW Unreserved | Amount of bandwidth that is available for reservation. |
