show ipv6 bgp filtered-routes detail output descriptions (Continued) TABLE 110
This field... Displays...
Origin The source of the route information. The origin can be one of the following:
• A - AGGREGATE - The route is an aggregate route for multiple networks.
• B - BEST - BGP4+ has determined that this is the optimal route to the destination.
• b - NOT-INSTALLED-BEST - BGP4+ has determined that this is the optimal route to the
destination but did not install it in the IPv6 route table because the device received better
routes from other sources (such as OSPFv3, RIPng, or static IPv6 routes).
• C - CONFED_EBGP - The route was learned from a neighbor in the same confederation
and AS, but in a different sub-AS within the confederation.
• D - DAMPED - This route has been dampened (by the route dampening feature), and is
currently unusable.
• E - EBGP - The route was learned through a in another AS.
• H - HISTORY - Route dampening is configured for this route, and the route has a history of
flapping and is unreachable now.
• I - IBGP - The route was learned through a in the same AS.
• L - LOCAL - The route originated on this device.
• M - MULTIPATH - BGP4+ load sharing is enabled and this route was selected as one of the
best ones to the destination. The best route among the multiple paths also is marked with
"B".
NOTE
If the "m" is shown in lowercase, the software was not able to install the route in the IPv6 route
table.
• S - SUPPRESSED - This route was suppressed during aggregation and thus is not
advertised to neighbors.
• F - FILTERED - This route was filtered out by BGP4+ route policies on the device, but the
saved updates containing the filtered routes.
Weight For information about this field, refer to Displaying filtered-out BGP4+ routes .
AS path The ASs through which routes with this set of attributes have passed. The local AS is shown in
parentheses.
Displaying route flap dampening statistics
To display route dampening statistics for all dampened routes, enter the following command at any
level of the CLI.
device# show ipv6 bgp flap-statistics

The ipv6-prefix and prefix-length parameters display statistics for the specified IPv6 prefix only. You
must specify the ipv6-prefix parameter in hexadecimal using 16-bit values between colons as
