ipv4-address: IPv4 address of a peer.
ipv6-address: IPv6 address of a peer.
Use the
debugging bgp graceful-restart
debugging for BGP.
Use the undo debugging bgp graceful-restart
debugging for BGP.
After this debugging is enabled, the debugging information of the BGP GR
operation will be displayed, including the currently triggered event, state
transitions, receiving/sending of EOR messages, and peer IP address. If a fault
occurs to the GR operation of BGP, you can display the debugging information for
fault location.
Enabling debugging may affect system performance; therefore, use the command
only when necessary and disable debugging once the debugging operation is
complete.
By default, this debugging is disabled.
