Step Command

Remarks

7.

Enable the PE to exchange
labeled routes with the

ASBR-PE in the same AS.

peer { group-name | ip-address
[ mask-length ] }
label-route-capability

By default, the PE does not
advertise labeled routes to any
IPv4 peer/peer group.

8.

Return to BGP view.

10.

Enable the PE to exchange
BGP VPNv6 routing

information with the EBGP

peer.

peer ip-address [ mask-length ]
enable

By default, the PE does not
exchange labeled routes with any

IPv4 peer/peer group.

Configuring the ASBR-PEs

In the inter-AS IPv6 VPN option C solution, an inter-AS LSP is needed, and the routes advertised between
the PEs and ASBRs must carry MPLS label information. The configuration is the same as that in the

Inter-AS IPv4 VPN option C solution. For more information, see "

Configuring MPLS L3VPN

."

Configuring the routing policy

A routing policy on an ASBR-PE does the following:

Assigns MPLS labels to routes received from the PEs in the same AS before advertising them to the
peer ASBR-PE.

Assigns new MPLS labels to the labeled routes to be advertised to the PEs in the same AS.

The configuration is the same as that in the Inter-AS IPv4 VPN option C solution. For more information,
see "

Configuring MPLS L3VPN

."

Configuring an OSPFv3 sham link

Before you configure an OSPFv3 sham link, configure basic IPv6 MPLS L3VPN (OSPFv3 is used between

PE and CE).

2.

Create a loopback interface
and enter loopback interface

view.

interface loopback interface-number

By default, no loopback
interface is created.

3.

Associate the loopback
interface with a VPN instance.

ip binding vpn-instance
vpn-instance-name

By default, the interface is
associated with no VPN

instance.

4.

Configure an IPv6 address for

the loopback interface.

See Layer 3—IP Services

By default, no IPv6 address is
configured for the loopback
interface.
