To reset a BGP connection using BGP soft reconfiguration, use the clear ip bgp EXEC command at the system prompt.
clear ip bgp {* | address | peer-groupname} [soft [in | out ]]
* Resets all current BGP sessions.
address Resets only the identified BGP neighbor.
peer-group-name Resets the specified BGP peer group.
soft (Optional) Soft reconfiguration.
in | out (Optional) Triggers inbound or outbound soft reconfiguration. If the in or out option is not specified, both inbound and outbound soft reconfiguration are triggered.
No reset is initiated.

If you specify BGP soft reconfiguration, by including the soft keyword, the sessions are not reset and the router sends all routing updates again. To generate new inbound updates without resetting the BGP session, the local BGP speaker should store all received updates without modification regardless of whether it is accepted by the inbound policy, using the neighbor soft-reconfiguration command. This process is memory intensive and should be avoided if possible. Outbound BGP soft configuration does not have any memory overhead. You can trigger an outbound reconfiguration on the other side of the BGP session to make the new inbound policy take effect.
Use this command whenever any of the following changes occur:
The following example resets all current BGP sessions:
clear ip bgp *
