IPv6 Multicast Commands
6-16
v1.0, July 2010
show ipv6 pimsm rphash
This command displays which rendezvous point (RP) is being used for a specified group.
show ipv6 pimsm rp mapping
Use this command to display all group-to-RP mappings of which the router is a aware (either
configured or learned from the bootstrap router (BSR)). If no RP is specified, all active RPs are
displayed.
IPv6 MLD Commands
IGMP/MLD Snooping is Layer 2 functionality but IGMP/MLD are Layer 3 multicast protocols. It
requires that in a network setup there should be a multicast router (which can act as a querier) to be
present to solicit the multicast group registrations. However some network setup does not need a
multicast router as multicast traffic is destined to hosts within the same network. In this situation,
the 7000 series has an IGMP/MLD Snooping Querier running on one of the switches and
Snooping enabled on all the switches. For more information, see
“IGMP Snooping Configuration
Commands” on page 3-139
and
“MLD Snooping Commands” on page 3-153
.

Use this command, in the administrative mode of the router, to enable MLD in the router.
