Displaying route flap dampening statistics for a BGP4+ neighbor
To display route flap dampening statistics for a specified BGP4+ neighbor, enter the following
command at any level of the CLI.
Syntax: show ipv6 bgp neighbor <ipv6-address> flap-statistics
The <ipv6-address> parameter displays the route flap dampening statistics for a specified
neighbor. You must specify this address in hexadecimal using 16-bit values between colons as
documented in RFC 2373.
This display shows the following information:
You also can display all the dampened routes by using the show ipv6 bgp dampened-paths
command. For more information, refer to
“Displaying dampened BGP4+ paths”
Communities
The communities that routes with this set of attributes are in.
AS Path
The ASs through which routes with this set of attributes have passed.
The local AS is shown in parentheses.

TABLE 213
Route flap dampening statistics for a BGP4+ neighbor
This field...
Displays...
Total number of flapping routes
The total number of routes in the neighbor’s BGP4+ route table that
have changed state and thus have been marked as flapping routes.
Status code
Indicates the status of the route, which can be one of the following:
•
> – This is the best route among those in the neighbor’s BGP4+
route table to the route’s destination.
•
d – This route is currently dampened, and thus unusable.
•
h – The route has a history of flapping and is unreachable now.
•
* – The route has a history of flapping but is currently usable.
Network
The destination network of the route.
From
The IPv6 address of the advertising peer.
Flaps
The number of flaps (state changes) the route has experienced.
Since
The amount of time (in hh:mm:ss) since the first flap of this route.
Reuse
The amount of time (in hh:mm:ss) after which the path is again
available.
Path
The AS path of the route.
