Reducing Source-active Message Flooding
RPs flood source-active messages to all of their peers away from the RP. When multiple RPs exist within a
domain, the RPs forward received active source information back to the originating RP, which violates the
RFP rule. You can prevent this unnecessary flooding by creating a mesh-group. A mesh in this context is a
topology in which each RP in a set of RPs has a peership with all other RPs in the set. When an RP is a
member of the mesh group, it forwards active source information only to its peers outside of the group.

Specify the RP Address Used in SA Messages
The default originator-id is the address of the RP that created the message. In the case of Anycast RP, there
are multiple RPs all with the same address. You can use the (unique) address of another interface as the
originator-id.
