This display shows the following information.
Displaying filtered-out BGP4+ routes
When you enable the soft reconfiguration feature, the Virtual ADX device saves all updates
received from the specified neighbor. The saved updates include those that contain routes that are
filtered out by the BGP4+ route policies in effect on the Virtual ADX
You can display a summary or more detailed information about routes that have been filtered out
by BGP4+ route policies.
To display a summary of the routes that have been filtered out by BGP4+ route policies, enter the
following command at any level of the CLI.
The routes displayed by the command are the routes that the Virtual ADX device’s BGP policies
filtered out. The Virtual ADX
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 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.
