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 the logs to be output correctly, you must also
configure information center on the device. For more information about the information center, see
Network Management and Monitoring Configuration Guide.
To enable logging for BGP route flapping:
Step Command Remarks
1. Enter system view.

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:
Task Command
Manually soft reset BGP sessions for
VPNv6 address family.
refresh bgp
[

instance-name ] { ipv4-address
[ mask-length ] |

address family.
