Step Command Remarks 4. Configure IPv6 MBGP inbound route filtering. • Configure inbound route filtering: filter-policy { acl6-number | ipv6-prefix ipv6-prefix-name } import Use any of the commands By default, advertised routes are not filtered. • Apply a routing policy to routes from a peer or a peer group: You can configure a filtering policy as required. peer { ipv6-group-name | ipv6-address } If you configure several route-policy route-policy-name import filtering policies, they are • Specify an IPv6 ACL to filter routes from a applied in the following peer or a peer group: sequence: peer { ipv6-group-name | ipv6-address } • filter-policy import filter-policy acl6-number import • peer filter-policy import • Specify an AS path list to filter IPv6 BGP • peer as-path-acl import routing information from a peer or a peer • peer ip-prefix import group: peer { ipv6-group-name | ipv6-address } • peer route-policy import as-path-acl as-path-acl-number import A filter policy can be applied • Specify an IPv6 prefix list to filter routes only after the previous one is from a peer or a peer group: passed. Routing information peer { ipv6-group-name | ipv6-address } can be received only after ipv6-prefix ipv6-prefix-name import passing all the configured filter policies. 5. Specify the upper limit of prefixes that can be peer { ipv6-group-name | ipv6-address } imported from a peer or route-limit limit [ percentage ] a peer group. 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. Configuring IPv6 MBGP route dampening Step 1. Enter system view. 2. Enter BGP view. 3.

Configure IPv6 MBGP
inbound route filtering.
Configure inbound route filtering:

import
Apply a routing policy to routes from a
peer or a peer group:
peer
{
ipv6-group-name

ipv6-address
}
route-policy

import
Specify an IPv6 ACL to filter routes from a
peer or a peer group:
peer

ipv6-address
}
filter-policy

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:
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.
5.
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.
