Displaying filtered-out BGP4+ routes

When you enable the soft reconfiguration feature, the switch saves all updates received from the
specified neighbor or peer group. The saved updates include those that contain routes that are
filtered out by the BGP4+ route policies in effect on the switch.
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.
BigIron RX# show ipv6 bgp filtered-routes

The routes displayed by the command are the routes that the switch's BGP policies filtered out. The
switch 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 switch 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] |
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.
