sham link.

Enabling logging for BGP routing 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.
To enable logging for BGP route flapping:
Step
1. Enter system view.
2. Enter BGP instance view.
3. Enter BGP VPNv6 address
family view.
4. Enable logging for BGP route
flapping.

Displaying and maintaining IPv6 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:
