RP is only involved in house-keeping, updating route tables etc. It plays no role in packet forwarding. It would take extra complexity + code to cause packet loss during such event, default is, no loss. For this eventuality linecards must run some soft of liveliness probe towards RP, so that when timer runs out, they voluntarily stop forwarding, so that they don't continue forwarding packets with stale routing information, which can lead to packet loss or compromise of L3 MPLS VPN security. -- ++ytti _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
