Displaying route flap dampening statistics
To display route dampening statistics for all dampened routes, enter the following command at any
level of the CLI.
Syntax: show ipv6 bgp flap-statistics [
<ipv6-prefix>/<prefix-length>
[longer-prefixes] |
as-path-filter
<number>
| neighbor
<ipv6-address> |
regular-expression
<regular-expression>
]
The
<ipv6-prefix>/<prefix-length>
parameter displays statistics for the specified IPv6 prefix 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.
The longer-prefixes keyword allows you to display statistics for routes that match a specified or
longer IPv6 prefix. For example, if you specify 2000::/16 longer-prefixes, then all routes with the
prefix 2002:: or that have a longer prefix (such as 2002:e016::/32) are displayed.
The as-path-filter
<number>
parameter specifies an AS path filter to display. Specify a filter
number.
The neighbor
<ipv6-address>
parameter displays statistics for routes learned from the specified
neighbor only. You also can display route flap statistics for routes learned from a neighbor by
entering the following command: show ipv6 bgp neighbor
<ipv6-address>
flap-statistics.
The regular-expression
<regular-expression>
parameter is a regular expression. The regular
expressions are the same ones supported for BGP4 AS-path filters.
You can also display route flap dampening statistics for a specified IPv6 neighbor. For more
information, refer to
“Displaying route flap dampening statistics for a BGP4+ neighbor”
on
page 1159.
This display shows the following information:
TABLE 187
Route flap dampening statistics
This field...
Displays...
Total number of flapping routes
The total number of routes in the switch’s BGP4+ route table that have
changed state and thus have been marked as flapping routes.
Status code
Indicates the dampening status of the route, which can be one of the
following:
•
> – This is the best route among those in the 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.
