Chapter 22: multicast Commands
22 - 4 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 min-
utes, 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.
Restrictions
None.
