Configuring Mbgp Route Dampening - HP A6600 Configuration Manual

If several filtering policies are configured, they are applied in the following sequence:
filter-policy import
•
peer filter-policy import
•
peer as-path-acl import
•
peer ip-prefix import
•
peer route-policy import
•
Members of a peer group can have different route reception filtering policies from the peer group. Only
the routes that have passed all the configured policies can be advertised.
To do...
1. Enter system view.
2. Enter BGP view.
3. Enter IPv4 MBGP address
family view.
4. Filter incoming routes using
an ACL or IP prefix list.
5. Reference a routing policy to
routes from an IPv4 MBGP
peer/peer group.
6. Reference an ACL to filter
routing information from an
IPv4 MBGP peer/peer group.
7. Reference an AS path ACL to
filter routing information from
an IPv4 MBGP peer/peer
group.
8. Reference an IP prefix list to
filter routing information from
an IPv4 MBGP peer/peer
group.
9. Specify the maximum number
of routes that can be received
from an IPv4 MBGP
peer/peer group.

Configuring MBGP route dampening

By configuring MBGP route dampening, you can suppress unstable routes from being added to the
MBGP routing table or being advertised to MBGP peers.
To do...
1. Enter system view.
2. Enter BGP view.
3. Enter IPv4 MBGP address
family view.
Use the command...
system-view
bgp as-number
ipv4-family multicast
filter-policy { acl-number |
ip-prefix ip-prefix-name } import
peer { group-name | ip-address }
route-policy policy-name import
peer { group-name | ip-address }
filter-policy acl-number import
peer { group-name | ip-address }
as-path-acl as-path-acl-number
import
peer { group-name | ip-address }
ip-prefix ip-prefix-name import
peer { group-name | ip-address }
route-limit limit [ percentage ]
Use the command...
system-view
bgp as-number
