Displaying BGP4+ information

Syntax: show ipv6 bgp neighbor ipv6-address routes best | detail [best | unreachable] |

unreachable

The ipv6-address parameter displays the routes for a specified neighbor. You must specify this
address in hexadecimal using 16-bit values between colons as documented in RFC 2373.

The best keyword displays the “best” routes, which are installed in the IPv6 route table.

The unreachable keyword displays the routes whose destinations are unreachable using any of the
BGP4+ paths in the IPv6 route table.

The detail keyword displays detailed information about the routes. If you do not specify this
parameter, a summary of the routes displays.

This display shows the following information.

TABLE 118

Summary of best and unreachable routes from a BGP4+ neighbor

This field...

Displays...

Number of accepted routes from
a specified neighbor

The number of routes displayed by the command.

Status codes

A list of the characters the display uses to indicate the route’s status. The
status code appears in the Status column of the display. The status codes are
described in the command’s output.

Prefix

LocPrf

The degree of preference for the route relative to other routes in the local AS.

the route with the higher local preference is chosen. The preference can have a
value from 0 – 4294967295.

Weight

The value that this device associates with routes from a specific neighbor. For
example, if the receives routes to the same destination from two BGP4+
neighbors, the prefers the route from the neighbor with the larger weight.
