Brocade FastIron Ethernet Switch Layer 3 Routing Configuration Guide - Manual (Page 541)

To clear all of the route flap dampening statistics for a neighbor, enter a command such as the following
at the Privileged EXEC level or any of the Config levels of the CLI.
device# clear ipv6 bgp neighbor 2001:db8:47::1 flap-statistics
Syntax: clear ipv6 bgp neighbor ipv6-address flap-statistics
The ipv6-address parameter specifies a neighbor by its IPv6 address. You must specify this address in
hexadecimal using 16-bit values between colons as documented in RFC 2373.
Specify the flap-statistics keyword to clear route flap dampening statistics for the specified neighbor.
Clearing and resetting BGP4+ routes in the IPv6 route table
You can clear all BGP4+ routes or only those routes associated with a particular IPv6 prefix from the
IPv6 route table and reset the routes. When cleared, the BGP4+ routes are removed from the IPv6 main
route table and then restored again.
For example, to clear all BGP4+ routes and reset them, enter the following command at the Privileged
EXEC level or any of the Config levels of the CLI.
device# clear ipv6 bgp routes
Syntax: clear ip bgp routes [ ipv6-prefix/prefix-length ]
The ipv6-prefix and prefix-length parameters clear routes associated with a particular IPv6 prefix. 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.
Clearing traffic counters for all BGP4+ neighbors
To clear the message counters (reset them to 0) for all BGP4+ neighbors, enter the following command.
device# clear ipv6 bgp traffic
Syntax: clear ipv6 bgp traffic
Displaying BGP4+ information
You can display the following BGP4+ information:
• BGP4+ route table.
• BGP4+ route information.
• BGP4+ route-attribute entries.
• BGP4+ configuration information.
• Dampened BGP4+ paths.
• Filtered-out BGP4+ routes.
• BGP4+ route flap dampening statistics.
• BGP4+ neighbor information.
• BGP4+ peer group configuration information.
• BGP4+ summary information.
