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 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 at least one command.
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.
