vrPpIpPortLogicalIfOspfIfMulticastForwarding
Virtual Router Passport Ip Port Logical If Ospf If Multicast Forwarding
The way multicasts should be forwarded on this interface; non forwarded, forwarded as data-link multicasts, or forwarded as data-link unicasts. Data-link multicasting is not meaningful on point-to-point and NBMA(No Broadcast Multi Access) interfaces, and setting this attribute to blocked effectively disables all multicast forwarding.
