as a router-id. A PIM First Hop router will register the source with the closest RP. The first RP that receives the register will re-encapsulate the register to all other Anycast RP peers. Please refer to Figure 9 as described in the configuration of PIM Anycast RP 100.1.1.1.

device(config)#interface loopback 2 device(config-lbif-2)#ip address 100.1.1.1/24 device(config-lbif-2)#ip pim-sparse device(config-lbif-2)#interface loopback 3 device(config-lbif-3)#ip address 1.1.1.1/24 device(config-lbif-3)#ip pim-sparse device(config-lbif-3)#router pim device(config-pim-router)#rp-address 100.1.1.1 device(config-pim-router)#anycast-rp 100.1.1.1 my-anycast-rp-set device(config-pim-router)#ip access-list standard my-anycast-rp-set device(config-std-nacl)#permit host 1.1.1.1 device(config-std-nacl)#permit host 2.2.2.2 device(config-std-nacl)#permit host 3.3.3.3

The RP shared address 100.1.1.1 is used in the PIM domain. IP addresses 1.1.1.1, 2.2.2.2, and

3.3.3.3are listed in the ACL that forms the self inclusive Anycast RP set. Multiple anycast-rp instances can be configured on a system; each peer with the same or different Anycast RP set.

NOTE

The PIM software supports up to eight PIM Anycast-RP routers. All deny statements in the anycast_rp_set acl and additional routers more than eight listed in an access list are ignored.

The example shown in the following figure is a PIM Anycast-enabled network with 3 RPs, 1 PIM-FH router connecting to its active source and local receiver. Loopback 2 in RP1, RP2, and RP3 have the same IP addresses 100.1.1.1. Loopback 3 in RP1, RP2, and RP3 each have separate IP addresses configured to communicate with their peers in the Anycast RP set.
