clear ip bgp

This command clears connections using hard or soft re-configuration.
Syntax
clear ip bgp {* | as-number | external | peer-group group-name |
neighbor-address} [in [prefix-list] | out | soft [in | out]]
* – All BGP peering sessions.
as-number – All peering sessions within this autonomous system number.
(Range: 1-4294967295)
external – All eBGP peering sessions.
peer-group group-name – A BGP peer group containing a list of
neighboring routers configured with the
neighbor-address – IPv4 address of a neighbor.
in – Inbound sessions.
prefix-list – The outbound route filter (ORF) prefix list. This option triggers
a new route refresh or soft re-configuration, which updates the ORF prefix
list. This option is ignored unless ORF capabilities have been enabled using
the neighbor capability orf prefix-list
information has been received from a sending peer. If ignored, a normal
inbound soft reset is performed.
out – Outbound sessions.
soft – Uses soft re-configuration for the reset, which does not tear down
the session.

Command Usage
◆
Use this command to initiate a hard reset or soft re-configuration. A hard reset
clears and rebuilds specified peering sessions and routing tables. Soft re-
configuration uses stored information to reconfigure and activate routing
tables without clearing existing sessions. It uses stored update information to
allow you to apply a new BGP policy without disrupting the network.
◆
To generate new inbound updates from stored information without resetting
peer sessions, you must preconfigure the local router using the
capability orf prefix-list
updates. Note that storing updates is memory intensive and should only be
applied to critical links.
Outbound soft configuration requires no memory or preconfiguration.
Outbound re-configuration can be used on the other side of a peering session
to make initiate a new inbound policy on the local side.
