MSDP Mesh-Group Configuration EX_msdp_0001 In this example: • MSDP 1, MSDP 2, and MSDP 3 are configured in a mesh-group called M1. • When the SA message is received at MSDP 1 on interface 10.1.1.1, MSDP 1 floods the message to MSDP 2 and MSDP 3. • MSDP 2 inserts the SA message, but the message is not forwarded to MSDP 3 because it is in the same mesh-group. • MSDP 3 inserts the SA message, but the message is not forwarded to MSDP 2 because it is in the same mesh-group. As this examples shows, a mesh-group limits the flooding of SA messages to neighboring peers in the mesh-group. In the configurations, loopback VLANs are used as the MSDP peer addresses. This is the recommended practice for MSDP. The same can be configured for the originator RP address also (CBSR and CRP also can be used as the loopback IP addresses). 772 | Chapter 29. MSDP
