Configuring BGP4+ Graceful Reset
The graceful restart feature for BGP4+ session reset is used so that any changes in network
configuration do not affect packet forwarding. The bgp graceful-restart graceful-reset
(BGP and BGP4+) command on page 3.33 invokes graceful restart only when a
configuration change forces a peer reset.
This example shows configuring BGP4+ graceful reset.
