Configuring BSRs and RPs for IPv6 PIM Sparse for a Specified VRF

After enabling IPv6 PIM SM globally and locally, you need to identify an interface on at least one device as a candidate IPv6 PIM Sparse Bootstrap Router (BSR) and candidate IPv6 PIM Sparse rendezvous point (RP). You can configure BSRs and RPs for a virtual routing and forwarding (VRF) instance.
This task assumes that you have configured the VRF.
Note: It is possible to configure the device as a candidate for either BSR or RP for a specified VRF, but it is recommended that you configure the same interface on the same device as both a BSR and an RP.
  1. Enter global configuration mode. 
    device# configure terminal
  2. Globally enable IPv6 PIM for a VRF. 
    device(config)# ipv6 router pim vrf blue
  3. Configure Ethernet interface 1/1/3 as the BSR candidate for the specified VRF with a mask length of 32 and a priority of 64. 
    device(config-ipv6-pim-router-vrf-blue)# bsr-candidate ethernet 1/1/3 32 64
  4. Set the IPv6 PIM BSR message interval timer. 
    device(config-ipv6-pim-router-vrf-blue)# bsr-msg-interval 16
    The BSR message interval timer is set to 16 seconds.
  5. Configure the device as a candidate RP for the specified VRF. 
    device(config-ipv6-pim-router-vrf-blue)# rp-candidate ethernet 1/1/3
  6. (Optional) To add a group number range for the configured RP candidate for a specified VRF, use the add option to explicitly add a range. 
    device(config-ipv6-pim-router-vrf-blue)# rp-candidate add ff02::200:2 64
  7. (Optional) To delete the configured RP candidate group ranges for a specified VRF, use the delete option to explicitly remove a range that was previously added. 
    device(config-ipv6-pim-router-vrf-blue)# rp-candidate delete ff02::200:1 128
    This example deletes an address group from the VRF for which it is a candidate RP.

The following example configures the IPv6 PIM Sparse interface on port 1/1/3 as a BSR candidate for VRF blue, with a hash mask length of 32 and a priority of 64. The same interface is also configured as an RP candidate for VRF blue. An explicit group address range is added. 

device# configure terminal
device(config)# ipv6 router pim vrf blue
device(config-ipv6-pim-router-vrf-blue)# bsr-candidate ethernet 1/1/3 32 64
device(config-ipv6-pim-router-vrf-blue)# bsr-msg-interval 16
device(config-ipv6=pim-router-vrf-blue)# rp-candidate ethernet 1/1/3
device(config-ipv6-pim-router-vrf-blue)# rp-candidate add ff02::200:2 64
