Dell Force10 Z9000 - Maximum-Paths

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.
Example
