Configuring Anycast RP
Figure 95 shows the mesh-group M1, which is comprised of three MSDP peers: MSDP 1,
MSDP 2, and MSDP 3. MSDP 5 is connected to MSDP 1, and MSDP 4 is connected to
MSDP 3; however, they are not part of the mesh-group.
Figure 95. MSDP Anycast RP Configuration
In Figure 95, all five routers are configured with the same loopback VLAN IP address
(1.1.1.1/32), and this address is configured in each router as an RP in the PIM SM domain.
Three RP routers (MSDP1, MSDP2, and MSDP3) are configured in the MSDP mesh
topology. The unicast routing mechanism ensures that all the non-RP routers in the domain
route join requests to the closest RP router.
Note: The anycast RP address must be unique to the loopback VLAN and
be the same on all anycast RP peers. It must not match the router IP
address, the PIM BSR address, or any other IP address used by the
router or any other network device.
The following sections provide example configurations for the switches shown in Figure 95:
• MSDP 1 Configuration on page 776
• MSDP 2 Configuration on page 776
• MSDP 3 Configuration on page 777
• MSDP 4 Configuration on page 778
• MSDP 5 Configuration on page 778
