Step Command Remarks • Specify the maximum number of prefixes that can be received from a peer or peer group: peer { group-name | Use one of the commands. ip-address } route-limit No limit is configured by default. prefix-number [ percentage-value ] If the specified maximum number is reached: • Specify the maximum number • For approach 1, the router of prefixes that can be received breaks down the BGP 3. Configure the maximum from a peer or peer group: connection to the peer. number of prefixes allowed to be received from a peer or peer group. peer { group-name | ip-address } route-limit prefix-number alert-only [ percentage-value ] • For approach 2, the router outputs alert information but does not break down the BGP connection to the peer. • Specify the maximum number of prefixes that can be received from a peer or peer group: peer { group-name | ip-address } route-limit prefix-number reconnect • For approach 3, the router breaks down the BGP connection to the peer and then reestablishes a BGP connection to the peer. reconnect-time [ percentage-value ] Configuring BGP route dampening By configuring BGP route dampening, you can suppress unstable routes from being added to the local routing table or being advertised to BGP peers. To configure BGP route dampening: Step 1. Enter system view. 2. Enter BGP view. 3. Configure BGP route dampening. Command system-view bgp as-number dampening [ half-life-reachable half-life-unreachable reuse suppress ceiling | route-policy route-policy-name ] * Remarks N/A N/A Not configured by default. Configuring a shortcut route An EBGP route received has a priority of 255, which is lower than a local route. This task allows you to configure an EBGP route as a shortcut route. It has the same priority as a local route and is more likely to become the optimal route. To configure a shortcut route: Step 1. Enter system view. 2. Enter BGP view.
