Users Guide

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.
