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 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:
1. filter-policy
import
2.
peer filter-policy import
3.
peer as-path-acl import
4.
peer ip-prefix import
5.
peer route-policy import
A filter policy can only be applied
after the previous one is passed.
Routing information can only be
received 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
