Once you enable the mcast AF in your IGP or BGP, IOS-XR will populate the muRIB, and PIM will use this one for RPF (before it used the unicast RIB/uRIB). This requires that all sources will be in the muRIB. This is different from IOS where RPF would fall back to the unicast RIB, as Michael described. The "rump always-replicate" command will replicate uRIB to muRIB, so we effectively achieve the IOS behaviour. oli _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
