Displaying and maintaining MPLS L3VPN
You can soft-reset or reset BGP sessions to apply new BGP configurations. A soft reset operation updates
BGP routing information without tearing down BGP connections. A reset operation updates BGP routing
information by tearing down, and then re-establishing BGP connections. Soft reset requires that BGP
peers have route refresh capability.
Execute the following commands in user view to soft reset or reset BGP connections:
Task Command
Soft reset BGP sessions for VPNv4
address family.
refresh bgp { ip-address [ mask-length ] | all | external | group
group-name | internal } { export | import } vpnv4 [ vpn-instance
vpn-instance-name ]
Reset BGP sessions for VPNv4
address family. reset bgp { as-number | ip-address [ mask-length ] | all | external |
internal | group group-name } vpnv4 [ vpn-instance vpn-instance-name ]
For more information about the refresh bgp vpnv4 and reset bgp vpnv4 commands, see Layer 3—IP
Routing Command Reference.
