Brocade Communications Systems FastIron X Series User Manual

This command enables soft reconguration for updates received from 10.10.200.102. The software dynamically resets the session with
the neighbor, then retains all route updates from the neighbor following the reset.
Syntax: [no] neighbor ip-addr | peer-group-name soft-reconguration inbound
NOTE
The syntax related to soft reconguration is
shown.
Placing a policy change into eect
To place policy changes into eect, 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
aect 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.

Displaying the ltered routes received from the neighbor or peer group
When you enable soft
reconguration, the device saves all updates received from the specied neighbor or peer group, including updates
that contain routes that are ltered out by the BGP4 route policies in eect on the device. To display the routes that have been ltered
out, enter the following command at any level of the CLI.
device# show ip bgp filtered-routes

The routes displayed are the routes that were
ltered 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 ltered-routes [ ip-addr ] | [ as-path-access-list num ] | [ detail ] | [ prex-list string ] [ longer-prexes ]
The ip-addr parameter species the IP address of the destination network.
The as-path-access-list num parameter species 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 rene the display request.
The prex-list string parameter species an IP prex list. Only routes permitted by the prex list are displayed.
