Filtering
Syntax: [no] neighbor ip-addr | peer-group-name soft-reconfiguration inbound
NOTE
The syntax related to soft reconfiguration is shown. For complete command syntax, refer to
on page 47 and
“Configuring a BGP4 peer group”
Placing a policy change into effect
To place policy changes into effect, enter a command such as the following.
Brocade(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. For complete command syntax, refer to
“Dynamically refreshing routes”
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.
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.
