The MSDP peers are fully meshed
The MSDP enabled router learns a new SA from a non-member of its mesh group
The SA passes the RPF check
Model 1: All multicast networks have peering agreements with one another. The full mesh MSDP is setup.
Model 2 : An inter-domain multicast provider exists. All multicast networks setup MSDP peering with the provider.
Note
Note
Since MSDP uses CLIP interface in its peering relation, the MSDP peer may not fall in any of the RFC rules and the MSDP SA messages will be rejected.
Controllers from the same SPB network must not have MSDP sessions with each other, regardless of whether mesh groups are used or not.
When using mesh groups, all Controllers within one SPB domain should peer with the same set of RPs and Controllers in adjacent domains, ie, one Controller should not peer with an RP that the other Controllers do not peer with.
