Configuring BGP Route Dampening

Configuring BGP Route Dampening

Context

A route is considered to be flapping when it repeatedly appears and then disappears in the routing table. BGP generally applies to complex networks where routes change frequently. Frequent route flapping consumes lots of bandwidths and CPU resources and even affects normal network operation. BGP route dampening prevents frequent route flapping.

BGP can differentiate routes based on policies and use different route dampening parameters to suppress different routes. For example, on a network, you can set a long suppression time for routes with a long mask and set a short suppression time for routes with a short mask (such as 8-bit mask).

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run bgp { as-number-plain | as-number-dot }

    The BGP view is displayed.

  3. Enter the corresponding address family view based on network type to configure BGP devices on networks.

    • Run ipv4-family { unicast | multicast | vpnv4 [ unicast ] | vpn-instance vpn-instance-name }

      The IPv4 address family view is displayed.

    • Run ipv6-family [ unicast | vpn-instance vpn-instance-name ]

      The IPv6 address family view is displayed.

  4. Run dampening [ ibgp ] [ half-life-reach reuse suppress ceiling | route-policy route-policy-name ] *

    BGP route dampening parameters are configured.

    NOTE:

    The dampening command is valid only for EBGP routes.

    The dampening ibgp command is valid only for BGP VPNv4 routes.
