Enabling logging for BGP route flapping
This feature enables BGP to generate logs for BGP route flappings that trigger log generation. The
generated logs are sent to the information center. For more information about information center, see
Network Management and Monitoring Configuration Guide.

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.
