Updating route information and resetting a neighbor session
25
Use the following CLI methods to configure soft configuration, apply policy changes, and display
information for the updates that are filtered out by the policies.
Enabling soft reconfiguration
To configure a neighbor for soft reconfiguration, enter a command such as the following.
PowerConnect(config-bgp-router)# neighbor 10.10.200.102 soft-reconfiguration
inbound
This command enables soft reconfiguration for updates received from 10.10.200.102. The
software dynamically refreshes or 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-reconfiguration inbound
NOTE
The syntax related to soft reconfiguration is shown. For complete command syntax, refer to “Adding
BGP4 neighbors” on page 756.
Placing a policy change into effect
To place policy changes into effect, enter a command such as the following.
PowerConnect(config-bgp-router)# 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 Layer 3 Switch 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” on page 848.
Displaying the filtered routes received from the neighbor or peer group
When you enable soft reconfiguration, the Layer 3 Switch saves all updates received from the
specified neighbor or peer group. This includes updates that contain routes that are filtered out by
the BGP4 route policies in effect on the Layer 3 Switch. To display the routes that have been filtered
out, enter the following command at any level of the CLI.
