Displaying BGP4 information

27

The no-best option displays the routes for which none of the routes to a given prefix were selected
as the best route. The IP route table does not contain a BGP4 route for any of the routes listed by
the command.

The not-installed-best option displays the routes received from the neighbor that are the best BGP4
routes to their destinations, but were nonetheless not installed in the IP route table because the
device received better routes from other sources (such as OSPF, RIP, or static IP routes).

The prefix-list <string> parameter filters the display using the specified IP prefix list.

The regular-expression <regular-expression> option filters the display based on a regular
expression. Refer to

“Using regular expressions”

on page 871.

The route-map <map-name> parameter filters the display using the specified route map. The
software displays only the routes that match the match statements in the route map. The software
disregards the route map’s set statements.

The summary option displays summary information for the routes.

The unreachable option displays the routes that are unreachable because the device does not
have a valid RIP, OSPF, or static route to the next hop.

Displaying the best BGP4 routes

To display all the BGP4 routes in the device’s BGP4 route table that are the best routes to their
destinations, enter a command such as the following at any level of the CLI.

Syntax: show ip bgp routes best

For information about the fields in this display, refer to

Table 141

Displaying BGP4 routes whose destinations are unreachable

To display BGP4 routes whose destinations are unreachable using any of the BGP4 paths in the
BGP4 route table, enter a command such as the following at any level of the CLI.
