Updating route information and resetting a neighbor session
30
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 1094.
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.
The routes displayed by the command are the routes that the Layer 3 Switch BGP4 policies filtered
out. The Layer 3 Switch 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 Layer 3 Switch 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>]
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 above shows
summary information.) You can specify any of the other options after detail to further refine the
display request.
The prefix-list <string> parameter specifies an IP prefix list. Only the routes permitted by the prefix
list are displayed.
NOTE
The syntax for displaying filtered routes is shown. For complete command syntax, refer to “Displaying
the BGP4 route table” on page 1080.
Displaying all the routes received from the neighbor
To display all the route information received in route updates from a neighbor since you enabled
soft reconfiguration, enter a command such as the following at any level of the CLI.
PowerConnect#show ip bgp filtered-routes
