Filtering
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.
The prefix-list string parameter specifies an IP prefix list. Only routes permitted by the prefix list are
displayed.
If you also use the optional longer-prefixes parameter, then all statistics for routes that match the
specified route or have a longer prefix than the specified route are displayed. For example, if you
specify 10.157.0.0 longer, then all routes with the prefix 10.157 or that have a longer prefix (such
as 10.157.22) are displayed.
NOTE
The syntax for displaying filtered routes is shown. For complete command syntax, refer to “Displaying
the BGP4 route table” on page 132.
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.
Syntax: show ip bgp neighbors ip-addr received-routes [detail]
The detail parameter displays detailed information for the routes. This example shows summary
information.
NOTE
The syntax for displaying received routes is shown. For complete command syntax, refer to
“Displaying BGP4 neighbor information” on page 122.
Dynamically requesting a route refresh from a BGP4 neighbor
You can easily apply changes to filters that control BGP4 routes received from or advertised to a
neighbor, without resetting the BGP4 session between the device and the neighbor. For example, if
you add, change, or remove a BGP4 IP prefix list that denies specific routes received from a
neighbor, you can apply the filter change by requesting a route refresh from the neighbor. If the
neighbor also supports dynamic route refreshes, the neighbor resends its Adj-RIB-Out, its table of
BGP4 routes. Using the route refresh feature, you do not need to reset the session with the
neighbor.
The route refresh feature is based on the following specifications:
Brocade# show ip bgp neighbor 192.168.4.106 routes
There are 97345 received routes from neighbor 192.168.4.106
