device(config-ipv6-pim-router)# rp-address 1001::1
device(config-ipv6-pim-router)# anycast-rp 1001::1 my-anycast-rp-set-acl
To configure PIM Anycast RP for a specified VRF, enter the commands as shown in the
following example.
device(config)# ipv6 router pim vrf blue
device(config-ipv6-pim-router-vrf-blue)# rp-address 1001::1
device(config-ipv6-pim-router-vrf-blue)# anycast-rp 1001::1 my-anycast-rp-set-acl
Syntax: [no] anycast-rp rp-address my-anycast-rp-set-acl
The rp address parameter specifies a shared RP address used among multiple PIM routers.
The my-anycast-rp-set-acl parameter specifies a host-based simple ACL used to specify the address of
the Anycast RP set, including a local address.
The following example is a configuration of PIM Anycast RP 1001:1.The example avoids using the
loopback 1 interface when configuring PIM Anycast RP because the loopback 1 address could be used
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. Refer to the figure
“Example of a PIM Anycast RP network” as described in the configuration of PIM Anycast RP 1001:1.
device(config)# interface loopback 2
device(config-lbif-2)# ipv6 address 1001::1/96
device(config-lbif-2)# ipv6 pim-sparse
device(config-lbif-2)# interface loopback 3
device(config-lbif-3)# ipv6 address 1:1:1::1/96
device(config-lbif-3)# ipv6 pim-sparse
device(config-lbif-3)# ipv6 router pim
device(config-ipv6-pim-router)# rp-address 1001::1
device(config-ipv6-pim-router)# anycast-rp 1001::1 my-anycast-rp-set
device(config-ipv6-pim-router)# ipv6 access-list my-anycast-rp-set
device(config-std-nacl)# permit ipv6 host 1:1:1::1 any
device(config-std-nacl)# permit ipv6 host 2:2:2::2 any
device(config-std-nacl)# permit ipv6 host 3:3:3::3 any
The RP shared address 1001:1 is used in the PIM domain. IPv6 addresses 1:1:1::1, 2:2:2::2, and
3:3:3::3 are 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 Anycast CLI applies to only PIM routers running RP. All deny statements in the anycast_rp_set
ACL are ignored.
The example shown in the figure “Example of a PIM Anycast RP network”is a PIM Anycast-enabled
network with three RPs and one PIM-FH router connecting to its active source and local receiver.
Loopback 2 in RP1, RP2, and RP3 each have the same IP addresses 1001:1. Loopback 3 in RP1, RP2,
and RP3 each have separate IP address configured to communicate with their peers in the Anycast RP
set.
