O RESET THE BGP CONNECTION USING DYNAMIC INBOUND SOFT RESET
If the BGP neighbor supports the route refresh capability, you can use the
dynamic soft reset method for resetting the inbound BGP table. The ‘clear ip bgp’
command with the soft in option allows you to perform a dynamic soft reset of the
inbound BGP table.

O CONFIGURE BGP SOFT RESET USING STORED ROUTING POLICY INFORMATION
For BGP neighbors who do not support the route refresh capability, previously
stored information can be used to generate a new set of BGP table updates. This
could potentially have higher memory overhead since additional routing
information needs to be stored.
The router needs to be configured to store the routing information it needs for this
kind of inbound soft reset as shown below:
The ‘clear ip bgp’ command can be used to initiate a soft reset which will
generate a new set of inbound BGP table updates based on the stored
information.
Command (in SUM/CM) Description
clear ip bgp {*|<neighbor-
address>|<peer-group-name>}
soft in
Performs a dynamic soft reset on the
connection specified in the command.
Command (in RCM) Description
neighbor {<ip-address>|<peer-
group-name>} soft-
reconfiguration inbound
Configures the router to start storing
updates.
Command (in SUM/CM) Description
clear ip bgp {*|<neighbor-
address>|<peer-group-name>}
soft in
Performs a soft reset on the connection
specified in the command, using the
stored routing table information for that
connection.
