Maintaining BGP

Maintaining BGP

Maintaining BGP includes resetting BGP connections and clearing BGP statistics.

Resetting BGP Connections

Context

Running the reset bgp command to reset BGP connections will interrupt BGP peer relationships between BGP devices. Exercise caution when you use this command.

When the BGP routing policy changes, for example, the switch modules does not support the route-refresh capability, reset BGP connections to make the modification take effect.

Procedure

  • To reset all BGP connections, run the reset bgp all command in the user view.
  • To reset the BGP connection with a specified AS, run the reset bgp { as-number-plain | as-number-dot } command in the user view.
  • To reset the BGP connection with a specified peer, run the reset bgp ipv4-address command in the user view.
  • To reset all EBGP connections, run the reset bgp external command in the user view.
  • To reset the BGP connection with a specified peer group, run the reset bgp group group-name command in the user view.
  • To reset all IBGP connections, run the reset bgp internal command in the user view.
  • To reset the MBGP connection with a specified peer, run the reset bgp multicast peer-address command in the user view.
  • To reset all MBGP connections, run the reset bgp multicast all command in the user view.
  • To reset the MBGP connection with all the peers in a specified peer group, run the reset bgp multicast group group-name command in the user view.
  • To reset all external connections, run the reset bgp multicast external command in the user view.
  • To reset all internal connections, run the reset bgp multicast internal command in the user view.

Clearing BGP Statistics

Context

BGP statistics cannot be restored after being cleared. Exercise caution when you reset BGP statistics.

Procedure

  • To clear route flapping statistics, run the reset bgp flap-info [ regexp as-path-regexp | as-path-filter as-path-filter-number | ipv4-address [ mask | mask-length ] ] command in the user view.
  • To clear route flapping statistics on a specified peer, run the reset bgp ipv4-address flap-info command in the user view.
  • To clear route dampening statistics and release suppressed routes, run the reset bgp dampening [ ipv4-address [ mask | mask-length ] ] command in the user view.
  • To clear MBGP route dampening statistics, run the reset bgp multicast dampening [ ip-address [ mask | mask-length ] ] command in the user view.
  • To clear MBGP route flapping statistics, run the reset bgp multicast flap-info [ ip-address [ mask | mask-length ] | as-path-filter { as-path-list-number | as-path-list-name } | regrexp regrexp ] command in the user view.
