Configuring IPv6 PIM Source-Specific Multicast

You can configure Source-Specific Multicast (SSM) on any interface that is IPv6 PIM SM enabled.
IPv6 PIM-SM must be enabled on any ports on which you want SSM to operate. Use the ssm-enable command under the IPv6 router PIM level to globally enable SSM filtering.

To enable SSM for a specified VRF, refer to the example after the task steps.

  1. Enter global configuration mode. 
    device# configure terminal
  2. Enable IPv6 PIM. 
    device(config)# ipv6 router pim
  3. Configure an SSM group range. The IPv6 address and mask specifies the multicast address for the SSM address range. 
    device(config-ipv6-pim-router)# ssm-enable range ff30::/12
  4. To display information for PIM SSM group ranges, use the show ipv6 pim sparse command. 
    device> show ipv6 pim sparse

  Register Stop Delay    : 10          Register Suppress interval : 60
  SSM Enabled            : Yes         SPT Threshold              : 1
  SSM Group Range        : ff30::/12
  Route Precedence       : mc-non-default mc-default uc-non-default uc-default
  Embedded RP Enabled    : Yes

The following example enables SSM for a specified VRF and a user-defined address range. 

device# configure terminal
device(config)# ipv6 router pim vrf blue
device(config-ipv6-pim-router-vrf-blue)# ssm-enable range ff30:/12
