5.1.1 Rendezvous Point Propagation
Rendezvous Points are supported either on border leaf switches or only outside the fabric. Server leaf switches or
spine switches are not supported as RPs. If the RP is located outside the fabric, then the border leaf switches will learn
of the RP-to-group mappings through one of the standard mechanisms of static configuration, Auto-RP, or BSR. Once
the BL switches have been informed of the RP-to-group mappings, they will advertise this information into the fabric
on the backbone VLAN via BGP SAFI messages. The BL switches will not use Auto-RP, BSR, or any PIM messaging to
inform server leaf switches of the RP-to-group mappings. Redundant border leaf switches should have the same view
of RP-to-group mappings, but if for some reason they do not, then the border leaf switch with higher backbone VLAN
IP address will be preferred by server leaf switches in the fabric.
