Configuring Inbound Ipv6 Mbgp Route Filtering - HP A8800 Configuration Manual

NOTE:
Members of an IPv6 MBGP peer group must have the same outbound route filtering policy as the peer
•
group.
IPv6 BGP advertises redistributed routes that pass the specified policy to the IPv6 MBGP peer.

Configuring inbound IPv6 MBGP route filtering

Step
1. Enter system view.
2. Enter BGP view.
3. Enter IPv6 MBGP address
family view.
4. Configure IPv6 MBGP
inbound route filtering.
5. Specify the upper limit of
prefixes that can be imported
from a peer or a peer group.
NOTE:
A peer can have an inbound route filtering policy that is different from the policy of the peer group that it
belongs to. That is, peer group members can have different inbound route filtering policies.
Command

bgp as-number
ipv6-family multicast
•
Configure inbound route
filtering:
filter-policy { acl6-number |
ipv6-prefix ipv6-prefix-name }
import
•
Apply a routing policy to routes
from a peer or a peer group:
peer { ipv6-group-name |
ipv6-address } route-policy
route-policy-name import
•
Specify an IPv6 ACL to filter
routes from a peer or a peer
group:
peer { ipv6-group-name |
ipv6-address } filter-policy
acl6-number import
•
Specify an AS path ACL to filter
IPv6 BGP routing information
from a peer or a peer group:
peer { ipv6-group-name |
ipv6-address } as-path-acl
as-path-acl-number import
•
Specify an IPv6 prefix list to
filter routes from a peer or a
peer group:
peer { ipv6-group-name |
ipv6-address } ipv6-prefix
ipv6-prefix-name import
peer { ipv6-group-name |
ipv6-address } route-limit limit

Use one of the approaches.
By default, advertised routes are
not filtered.
You can configure a filtering policy
as required.
If you configure several filtering
policies, 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
A filter policy can be applied only
after the previous one is passed.
Routing information can be
received only after passing all the
configured filter policies.
Optional.
The number is unlimited by default.
