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.
Use the following commands to soft reset or reset BGP connections:
