Displaying BGP4+ information
The routes displayed by the command are the routes that the device’s BGP policies filtered out. The
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 user does not need to request the route information from
the neighbor, but instead uses the information in the updates.
Syntax: show ipv6 bgp filtered-routes [ipv6-prefix/prefix-length [longer-prefixes] |
[as-path-access-list name] | [prefix-list name]
The ipv6-prefix/prefix-length parameter displays the specified IPv6 prefix of the destination
network only. You must specify the ipv6-prefix parameter in hexadecimal using 16-bit values
between colons as documented in RFC 2373. You must specify the prefix-length parameter as a
decimal value. A slash mark (/) must follow the ipv6-prefix parameter and precede the prefix-length
parameter.
The longer-prefixes keyword allows you to display routes that match a specified or longer IPv6
prefix. For example, if you specify 2001:db8::/32 longer-prefixes, then all routes with the prefix
2001:db8::/32 or that have a longer prefix (such as 2001:db8:e016::/48) are displayed.
The as-path-access-list name parameter specifies an AS-path ACL. Specify an ACL name. Only the
routes permitted by the AS-path ACL are displayed.
The prefix-list name parameter specifies an IPv6 prefix list. Only the routes permitted by the prefix
list are displayed.
This display shows the following information.
TABLE 105 Summary of filtered-out BGP4+ route information
This field... Displays...
Number of BGP4+ Routes
matching display condition The number of routes that matched the display parameters you entered. This is
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 left column of the display, to the left of each route.
The status codes are described in the command’s output. The status column
displays an “F” for each filtered route.
Prefix The network address and prefix.
Next Hop The next-hop router for reaching the network from the device.
MED The value of the route’s MED attribute. If the route does not have a metric, this
field is blank.
LocPrf The degree of preference for this route relative to other routes in the local AS.
When the BGP4+ algorithm compares routes on the basis of local preferences,
the route with the higher local preference is chosen. The preference can have a
value from 0 – 4294967295.
