ACL for RP candidate
Supports features described in RFC
2362.
Supports features described in RFC
1075.
You must configure a fully meshed
topology between MSDP peers. This is
mandated for this release because of lack
of any EGP that provides a peer RPF
check for SA messages.
Anycast RP is a method of providing
intra-domain redundancy and loadbalancing between multiple Rendevous
Points (RP) in a Protocol Independent
Multicast Sparse mode (PIM-SM)
network.
Limits the multicast groups that are
covered by a static (RP). It controls the
multicast groups for which candidate
RPs send advertisement messages to
bootstrap routers.
