Maintaining BGP4+

Maintaining BGP4+

Maintaining BGP4+ involves resetting BGP4+ connections, clearing BGP4+ statistics, and debugging BGP4+.

Resetting BGP4+ Connections

Resetting BGP4+ connections interrupts peer relationships.

Context

BGP4+ peer relationships between routers are deleted if you reset BGP4+ connections using the reset bgp ipv6 command. Exercise caution when resetting BGP4+ connections.

When a BGP4+ routing policy (the router does not support the router-fresh capability) is changed, reset BGP connections so that the new configuration can take effect. To reset BGP4+ connections, run any of the following commands in the user view:

Procedure

  • Run the reset bgp ipv6 all command to reset all BGP4+ connections.
  • Run the reset bgp ipv6 as-number command to reset a BGP4+ connection between two devices in different ASs.
  • Run the reset bgp ipv6 ipv4-address command to reset a BGP4+ connection between specified BGP4+ peers.
  • Run the reset bgp ipv6 external command to reset all EBGP connections.
  • Run the reset bgp ipv6 internal command to reset all IBGP connections.

Clearing BGP4+ Statistics

Clearing BGP4+ statistics involves clearing route flapping statistics and route dampening statistics.

Context

BGP4+ statistics cannot be restored after they are cleared. Exercise caution when using reset commands.

Procedure

  • Run the reset bgp ipv6 flap-info [ regexp as-path-regexp | as-path-filter { as-path-filter-number | as-path-filter-name } | ipv6-address prefix-length ] command in the user view to clear route flapping statistics.
  • Run the reset bgp ipv6 ipv6-address flap-info command in the user view to clear route flapping statistics on a specified peer.
  • Run the reset bgp ipv6 dampening [ ipv6-address prefix-length ] command in the user view to clear route dampening statistics and release suppressed routes.
