Configuring Bgp Route Dampening; Configuring A Shortcut Route - HP 6125G Configuration Manual

Step
3. Configure the maximum
number of prefixes allowed to
be received from a peer or
peer group.

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.

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.

Remarks
Use one of the commands.
No limit is configured by default.
If the specified maximum number is
reached:
•
For approach 1, the router
breaks down the BGP
connection to the peer.
•
For approach 2, the router
outputs alert information but
does not break down the BGP
connection to the peer.
•
For approach 3, the router
breaks down the BGP
connection to the peer and then
reestablishes a BGP connection
to the peer.
