    Creating IPv6 Mroute Port Limits

    When a multicast forwarding entry (that is, an mroute) is added with an OIF on a port, the OIF count for that port is incremented. If you configure a port limit and the OIF count on the port count exceeds that limit, no OIFs on that port are added to mroutes (that is, new OIFs are blocked).

    To configure a limit on the number of mroute OIFs that can be added across different virtual routers on a port:

    • Issue the mroute port limit command in Global Configuration mode.
      host1(config)#mroute port 3/0 limit 10

    Use the no version to remove any OIF port limits.
