Step
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.
Configuring IPv6 MBGP route dampening
Step
1.
Enter system view.
2.
Enter BGP view.
3.
Enter IPv6 MBGP address
family view.
4.
Configure IPv6 MBGP route
dampening parameters.
Configuring IPv6 MBGP route attributes
This section describes how to use IPv6 MBGP route attributes to affect IPv6 MBGP route selection. IPv6
MBGP route attributes involve:
Command
•
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
peer { ipv6-group-name | ipv6-address }
route-limit limit [ percentage ]
Command
system-view
bgp as-number
ipv6-family multicast

half-life-unreachable reuse

Remarks
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.
Optional.
The number is unlimited by
default.
