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 reestablishing 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 sessions:
Task | Command |
|---|---|
Soft reset BGP sessions for VPNv4 address family. | refresh bgp { ip-address | 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 | all | external | internal | group group-name } vpnv4 [ vpn-instance vpn-instance-name ] |
