    Configuring MLD SSM Mapping

    SSM mapping statically assigns sources to MLDv1 groups. You must use SSM mapping for MLDv1 hosts to interoperate with PIM SSM. SSM mapping allows the router to use a statically configured list to translate (*,G) memberships to (S,G) memberships.

    The ipv6 mld ssm-map static command uses IPv6 access lists, which allow both source and destination/group addresses to be specified. You must set the source address to “any”.

    To statically configure SSM mapping:

    1. Enable SSM mapping on the router.
      host1:boston(config)#ipv6 mld ssm-map enable

      Use the no version to disable the SSM map.

    2. Specify an access list and source address for use in SSM mapping.
      host1:boston(config)#ipv6 mld ssm-map static boston-list 2001::1

      Use the no version to remove the SSM map association.

      Note: To operate correctly, the static source addresses must fall within the configured PIM SSM range.
