Displaying BGP4+ information
9
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” on page 329.
Displaying last error packet from a BGP4+ neighbor
You can display information about the last packet that contained an error from any of a Virtual ADX
device’s neighbors. The displayed information includes the error packet's contents decoded in a
human-readable format.
For example, to display information about the last error packet from any of a Virtual ADX device’s
neighbors, enter the following command.
Syntax: show ipv6 bgp neighbor last-packet-with-error
This display shows the following information.
TABLE 13 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.
TABLE 14 Last error packet information for BGP4+ neighbors
This field... Displays...
Total number of BGP Neighbors The total number of configured neighbors for a Virtual ADX device.
Last error The error packet’s contents decoded in a human-readable format or
notification that no packets with an error were received.
Virtual ADX# show ipv6 bgp neighbor last-packet-with-error
Total number of BGP Neighbors: 266
No received packet with error logged for any neighbor
