• IPv6 BGP advertises the redistributed routes that pass the specified policy to the IPv6 MBGP peer.

4. Configure IPv6 MBGP
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 list 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:
5. filter-policy import
6. peer filter-policy import
7. peer as-path-acl import
8. peer ip-prefix import
9. 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.
10. 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:
peer can have an inbound route filterin
policy that is different from the policy of the peer
roup that i
belongs to. That is, peer group members can have different inbound route filtering policies.
