Users Guide
through the new router, other routers will not use a path through the router as a transit path to forward trac to
other networks.
Use the max-metric router-lsa command to gracefully shut down or reload a router without dropping packets
destined for other networks.
NOTE: If you enter the max-metric router-lsa command without an option (on-startup
announce-time
or on-startup wait-for-bgp [
wait-time
]), the maximum metric of 65535 is always announced in LSAs
sent by the router.
