Configure Graceful BGP Restart

To configure a router to perform graceful BGP (Border Gateway Protocol) 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 | ipv6-unicast | ipv6-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
You can use the following commands to verify the BGP graceful restart configuration:
show bgp

show bgp {neighbor} remoteaddr {address-family [ipv4-unicast | ipv4-multicast |ipv6-unicast | ipv6-multicast | ipv4-vxlan]} [accepted-routes | received-routes | rejected-routes | transmitted-routes] {detail} [all | as-path path-expression | community [no-advertise | no-export | no-export-subconfed | number community_number | autonomous-system-id : bgp-community] | network [any/netMaskLen | networkPrefixFilter] {exact}]
