The forwarding-engine will continue to forward packets for 300 seconds when
it loses connectivity with the routing-engine. This will give adjacent
routers the opportunity to have their routing-protocols "time-out" on
the affected node. 

A forwarding-engine which has lost connectivity to the routing-engine
will not forward packets for ever.
