Limiting Prefixes Received From A Peer Or Peer Group; Configuring Bgp Route Dampening - HP 3600 v2 series Configuration Manual

in addition to the reachability check of the next hop, the BGP router must find an active IGP route with the
same destination network segment before it can advertise the iBGP route (use the display ip routing-table
protocol command to check the IGP route state).
Follow these steps to enable BGP and IGP synchronization:
To do...
Enter system view
Enter BGP view
Enable synchronization between
BGP and IGP

Limiting prefixes received from a peer or peer group

Follow these steps to configure the maximum number of prefixes allowed to be received from a peer or
peer group:
To do...
Enter system view
Enter BGP view
Specify the maximum number of
prefixes that can be received from
a peer or peer group.
If the number is reached, the router
breaks down the BGP connection
to the peer.
Specify the maximum number of
prefixes that can be received from
a peer or peer group.
If the number is reached, 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.
If the number is reached, the router
breaks down the BGP connection
to the peer and then reestablishes
a BGP connection to the peer.

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.
Follow these steps to configure BGP route dampening:
Use the command...
system-view
bgp as-number
synchronization
Use the command...
system-view
bgp as-number
peer { group-name | ip-address }
route-limit prefix-number
[ percentage-value ]
peer { group-name | ip-address }
route-limit prefix-number alert-only
[ percentage-value ]
peer { group-name | ip-address }
route-limit prefix-number reconnect
reconnect-time [ percentage-value ]
