show ip mroute route

Display information about the multicast routes set up on the switch. The range of values depends on the hardware platform.

Syntax

show ip mroute route
show ip mroute route vrf WORD<1-16>
show ip mroute route vrf WORD<1-32>
show ip mroute route vrfids WORD<0-255>
show ip mroute route vrfids WORD<0-512>

Command Parameters

vrf WORD<1-32> | vrf WORD<1-16>: Specifies a VRF by name. Range depends on hardware platform.
vrfids WORD <0-255> | vrfids WORD <0-512>: Specifies a VRF by ID. Range depends on hardware platform.

Default

None

Command Mode

User EXEC

Usage Guidelines

This command is not supported on a node configured as the DvR Leaf within a DvR domain.

In this output, every stream uses one (*,G) entry and x (S,G) entries, depending on how many servers forward traffic to the same group.

The 0.0.0.0 mask is always tied to a (*,G) entry.

Every time a new stream comes in, Protocol Independent Multicast (PIM) creates two entries in the table; one is a (*,G) entry that points toward the rendezvous point (RP) router, and the other is an (S,G) entry that points toward the source.

Command Output

The show ip mroute route command displays the following information:


Output field	Description
GROUP	Indicates the IP multicast group for this multicast route.
SOURCE	Indicates the network address that, when combined with the corresponding value of SRCMASK, identifies the sources for this multicast route.
SRCMASK	Indicates the network mask that, when combined with the corresponding value of SOURCE, identifies the sources for this multicast route.
UPSTREAM_NBR	Indicates the address of the upstream neighbor from which IP datagrams from these sources to this multicast address are received, or 0.0.0.0 if the (S,G) source is local or if the RP for this the (*,G) group is an address on this router.
IF	Indicates the value of ifIndex for the interface that receives IP datagrams sent by these sources to this multicast address. A value of 0 in a (*,G) route indicates that datagrams are not subject to an incoming interface check, but datagrams can be received on any interface.
EXPIR	Indicates the minimum amount of time remaining before this entry ages out. The value 0 indicates that the entry is not subject to aging. Note: The value you configure for fwd-cache-timeout applies only to the locally learned sender; it does not apply to SMLT synchronized sender records.
PROT	Indicates the multicast protocol through which the switch learned this route.

Example

The following example displays information about the multicast routes on the switch.
