Syntax Description:

• AS-number— Resets all neighbors in the specified autonomous system.

• neighbor-ip-address— Resets the specified BGP neighbor.

• peer-group-name— Resets all neighbors in the specified peer group.

Purpose: To reset a BGP connection. BGP neighbor connections can be reset based on the neighbor’s IP address, the neighbor’s autonomous system number, or the peer group name. You must reset a BGP connection when any of the following have been modified or added to:

• BGP access list

• BGP distribute list

• BGP route map

• BGP timers

• BGP weights

• BGP administrative distance

Clearing a BGP connection without the soft keyword causes the neighbor relationship to transition from Established to Idle. The neighbor relationship is then reestablished, and the new routing policies take effect. If the soft keyword is used, the session is not reset, and all routing updates are resent. When you use the soft in option, the local BGP configuration should include the neighbor soft-reconfiguration command (see section 8-30). Using the soft in option is memory-intensive. Using soft out for outbound reconfiguration does not incur additional memory overhead. Using soft in out is equivalent to using just soft.
