Andy, >While RFC3478 makes no specific comment on how to do so, a possible >approach would be that when a node detects the failure of a peer >through receipt of a Notification (shutdown), the receiving node >assumes this is a planned shutdown of the peer, and disables graceful >restart. > I think the shutdown notification has a wider meaning; anytime the LSR chooses to terminate a session, it sends the shutdown msg. e.g. during Software upgrades, manual process restarts etc. That still means that the forwarding state is intact. A better idea is probably to delete the label mappings from the peer explicitly during planned shutdown. Thanks/Pradosh >In all other cases (TCP socket error, keepalive timeout etc.), the node >assumes unplanned shutdown, and starts its graceful restart neighbour >reconnect / liveness timer for the session. > >I'd like to get clarification if this is in fact the intent in the >standard? > >Thanks, > >Andy. > >_______________________________________________ >mpls mailing list >mpls@lists.ietf.org https://www1.ietf.org/mailman/listinfo/mpls _______________________________________________ mpls mailing list mpls@lists.ietf.org https://www1.ietf.org/mailman/listinfo/mpls |
