Anycast Rendezvous Point (RP) Using PIM
(RFC 4610)
This feature provides support for RFC 4610-based Anycast Rendezvous Point
(RP), which provides fast convergence when RP routers fail using PIM protocol without
using the source discovery protocol Multicast Source Discovery Protocol (MSDP) for both
IPv4 and IPv6 address families.
The feature requires a Premier or Core license. For more information about licensing, see

Supported Platforms
ExtremeSwitching X450-G2, X460-G2, X465, X590, X670-G2, X690, X695, X870, and 5520
series switches.
Limitation
The following limitations apply to this feature:
- Configuring MSDP peers
between the Anycast RPs might not work as expected. Anycast RP Using PIM
removes the dependence on using MSDP by removing MSDP peering between the
Anycast-RPs.
- Register policy on an RP will
reject the register source or groups mentioned in the policy file. If
Anycast RP is configured on the same node, register policy takes precedence
over the Anycast RP. Register policy filter is applied on all the
PIM-Register messages received from either first hop router (FHR) or other
Anycast RP peers.
- If RP is configured on an
MLAG node, the peer node must not be configured as Anycast RP peer.
New CLI Commands
