multicast show mroutes
458 SSR Command Line Interface Reference Manual
multicast show mroutes
Purpose
Display the IP multicast routing table.
Format
multicast show mroutes [child <IPaddr>] [group <ipaddr>] [parent <IPaddr>]
Mode
Enable
Description
The multicast show mroutes command displays the IP multicast routing table entry for
the specified multicast group address.
This command lists all the multicast distribution trees, showing the parent interface (from
where the traffic is coming), and the children distribution interfaces (to which the traffic is
being forwarded). It would also show any cache information available either in hardware
forwarding mechanism or in the main processor (for software based forwarding).
Note:
The cache information can be timed out when not enough traffic is present, but
multicast routes can still be present. Cache information is presented in number of
flows (Layer 4 sessions). Multicast routes stay at least for 5 minutes, while the
hardware forwarding mechanism can time out a flow faster.
Any pruning information if present is also shown.
The search can always be narrowed by looking at a particular group, and/or looking at a
particular parent interface, and/or looking at a particular child interface.
Multicast routes are not the same as DVMRP routes.
Parameters
child <ipaddr> Address of a child interface.
group <ipaddr> Address of a multicast group.
parent <ipaddr> Address of a parent interface.
