be a receiver only, and not to do graceful restarts itself.
Configuring Graceful BGP Restart
To configure a router to perform graceful BGP restart, use the following command:
configure bgp restart [none | planned | unplanned | both | aware-only]
The address families participating in graceful restart are configured using the following
command:
configure bgp restart [add | delete] address-family [ipv4-unicast |
ipv4-multicast]
There are three timers that can be configured with the following commands:
configure bgp restart restart-time <seconds>
configure bgp restart stale-route-time <seconds>
configure bgp restart update-delay <seconds>
