PIM for IPv6 RP Address
This window is used to display and configure the IPv6 PIM RP address settings. This feature only affects PIM-SM
operation. Use this feature to statically define the RP address for multicast groups that are to operate in sparse mode.
Use a single RP for more than one group. The conditions specified by the access list determine for which groups the
RP can be used. Multiple RP can be defined, each with a single access list. The new setting overrides the old one.
All routers in a domain should have a consistent multicast group to RP mapping. The first hop router that initiates a
register message will use the mapping entries to determine the RP for sending the PIM register message destined for
a specific group. The last hop router that initiates a join message uses the mapping entries to determine the RP for
sending the join and prune message for a specific group. When a router receives a join message, it will check the
mapping entries for forwarding of the message. When a RP receives a register message, if the router is not the right
RP for the multicast group, a register-stop message will be sent.
If the PIM domain is using embedded-RP, only the RP needs to be statically configured as the RP for the embedded
RP ranges. The other routers will discover the RP address from the IPv6 group address. If these routers want to select
a static RP instead of the embedded RP, the specific embedded RP group range must be configured in the access list
of the static RP.
