inbound route filtering

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

Use any of the commands
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.

Specify the upper limit of
prefixes that can be imported

from a peer or a peer group

peer { ipv6-group-name | ipv6-address }
route-limit limit [ percentage ]

Optional
The number is unlimited by
default.

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.
