10.
Apply a routing policy to
routes
advertised
to or
received from the peer or
peer group.
peer
{
group-name
|
ip-address
[
mask-length
] }
route-policy
route-policy-name
{
export
|
import
}
By default, no routing policy is
applied for a peer.
11.
Enable route target filtering
for received BGP VPNv6
routes.
policy vpn-target
By default, route target filtering is
enabled.
12.
Configure the local PE as the
route reflector and specify
the peer as the client.
peer
{
group-name
|
ip-address
[
mask-length
] }
reflect-client
By default, no route reflector or
client is configured.
13.
Specify the maximum
number of routes BGP can
receive from a peer or peer
group.
peer
{
group-name
|
ip-address
[
mask-length
] }
route-limit
prefix-number
[ {
alert-only
|
discard
|
reconnect
reconnect-time
} |
percentage-value
] *
By default, the number of routes
that BGP can receive from a peer
or peer group is not limited.
14.
Enable route reflection
between clients.
reflect between-clients
By default, route reflection
between clients is enabled.
15.
Configure a cluster ID for the
route reflector.
reflector cluster-id
{
cluster-id
|
ip-address
}
By default, an RR uses its own
router ID as the cluster ID.
If more than one RR exists in a
cluster, use this command to
configure the same cluster ID for
all RRs in the cluster to avoid
routing loops.
16.
Configure filtering of
reflected routes.
rr-filter
extended-community-number
By default, an RR does not filter
reflected routes.
Only IBGP routes whose
extended
community attribute
matches the specified community
list are reflected.
By configuring different filtering
policies
on RRs, you can
implement load balancing among
the RRs.
Configuring inter-AS IPv6 VPN
If the MPLS backbone spans multiple ASs, you must configure inter-AS IPv6 VPN.
There are three inter-AS VPN solutions (for more information, see "
"). IPv6
MPLS L3VPN supports only inter-AS VPN option A and option C.
Before configuring inter-AS IPv6 VPN, complete these tasks:
•
Configure an IGP for the MPLS backbone in each AS to ensure IP connectivity.
•
Configure basic MPLS for the MPLS backbone of each AS.
•
Configure MPLS LDP for the MPLS backbones so that LDP LSPs can be established.
The following sections describe inter-AS IPv6 VPN option A and option C. Select one according to
your network scenario.
