NOTE
The syntax related to soft reconfiguration is shown.
Placing a policy change into effect
To place policy changes into effect, enter a command such as the following.
device(config-bgp)# clear ip bgp neighbor 10.10.200.102 soft in
This command updates the routes by comparing the route policies against the route updates that the
device has stored. The command does not request additional updates from the neighbor or otherwise
affect the session with the neighbor.
Syntax: clear ip bgp neighbor ip-addr | peer-group-name soft in
NOTE
If you do not specify in , the command applies to both inbound and outbound updates.
NOTE
The syntax related to soft reconfiguration is shown.
Displaying the filtered routes received from the neighbor or peer group
When you enable soft reconfiguration, the device saves all updates received from the specified
neighbor or peer group, including updates that contain routes that are filtered out by the BGP4 route
policies in effect on the device. To display the routes that have been filtered out, enter the following
command at any level of the CLI.
device# show ip bgp filtered-routes
Searching for matching routes, use ^C to quit...

The routes displayed are the routes that were filtered out by the BGP4 policies on the device. The
device did not place the routes in the BGP4 route table, but did keep the updates. If a policy change
causes these routes to be permitted, the device does not need to request the route information from
the neighbor, but instead uses the information in the updates.
Syntax: show ip bgp filtered-routes [ ip-addr ] | [ as-path-access-list num ] | [ detail ] | [ prefix-list
string ] [ longer-prefixes ]
The ip-addr parameter specifies the IP address of the destination network.
The as-path-access-list num parameter specifies an AS-path ACL. Only the routes permitted by the
AS-path ACL are displayed.
The detail parameter displays detailed information for the routes. (The example shows summary
information.) You can specify any of the other options after detail to further refine the display request.
