Displaying information for an IPv6 PIM Anycast RP interface

To display information for an IPv6 PIM Anycast RP interface, enter the show ipv6 pim anycast-rp
command.

device(config)# show ipv6 pim anycast-rp

Number of Anycast RP: 1

Anycast RP: 1001::1

  ACL ID: 200

  ACL Name: my-anycast-rp-set

  ACL Filter: SET

  Peer List:

   1:1:1::1

   2:2:2::2

   3:3:3::3

Syntax: show ipv6 pim [ vrf vrf-name ] anycast-rp

The vrf parameter allows you to display information for an IPv6 Anycast RP interface for the VRF
instance identified by the vrf-name variable.

The following table describes the parameters of the show ipv6 pim anycast-rp command.

Output from the show ipv6 pim anycast-rp command

Number of Anycast RP

Specifies the number of Anycast RP sets in the multicast domain.

Anycast RP

Specifies a shared RP address used among multiple PIM routers.

ACL ID

Specifies the ACL ID assigned.

ACL Name

Specifies the name of the Anycast RP set.

ACL Filter

Specifies the ACL filter state SET or UNSET.

Peer List

Specifies host addresses that are permitted in the Anycast RP set.

Multicast Listener Discovery and source-specific multicast protocols

Multicast Listener Discovery Version 2 (MLDv2) protocol is supported. IPv6 routers use the MLDv2
protocol to discover multicast listeners, or nodes that wish to receive multicast packets on directly
attached links. MLDv2 supports source filtering, the ability of a node to send reports on traffic that is
from a specific address source or from all multicast addresses except the specified address sources.
The information is then provided to the source-specific multicast (SSM) routing protocols such as PIM-
SSM.

The IPv6 router stores a list of multicast addresses for each attached link. For each multicast address,
the IPv6 router stores a filter mode and a source list. The filter mode is set to INCLUDE if all nodes in
the source list for a multicast address are in the INCLUDE state. If the filter mode is INCLUDE, then
only traffic from the addresses in the source list is allowed. The filter mode is set to EXCLUDE if at
least one of the nodes in the source list is in an EXCLUDE state. If the filter mode is EXCLUDE, traffic
from nodes in the source list is denied and traffic from other sources is allowed.
