Configuration Roadmap
The configuration roadmap is as follows:
1. Set up the EBGP peer relation between the PE and the CE and set up MP-IBGP peer relation
between the PE and the ASBR.
2. Create an IPv6 VPN instance on each ASBR and bind each instance to the interface
connected to the other ASBR (regarding the ASBR as its CE) and set up the EBGP peer
relation between the ASBR.
Data Preparation
To complete the configuration, you need the following data:
l MPLS LSR IDs of PEs and ASBR-PEs
l IPv6 VPN instance names, RDs, and VPN targets for the PEs and ABSRs
Procedure
Step 1 Specify the VLAN IDs that are allowed by the interfaces, as shown in Figure 4-5.
The configuration procedure is not mentioned here.
Step 2 On the MPLS backbone networks in AS 100 and AS 200, configure an IGP protocol so that the
PEs and the ASBRs on the network can communicate with each other.
The OSPF protocol is used in this example and the configuration procedure is not mentioned
here.
NOTE
The 32-bit loopback interface address used as the LSR ID must be advertised by OSPF.
After the configuration, the OSPF neighbor relation can be established between the ASBR and
the PE in the same AS. Run the display ospf peer command, and you can find that the neighbor
status is Full.
The ASBR and PE in the same AS can ping each other and learn the loopback interface address
of each other.
Step 3 Configure the basic MPLS function and MPLS LDP on the MPLS backbone networks of AS
100 and AS 200 and set up the MPLS LDP LSP.
# Configure the basic MPLS function on PE1 and enable LDP on the interface connected to
ASBR-PE1.
<PE1> system-view
[PE1] mpls lsr-id 1.1.1.9
[PE1] mpls

[PE1] mpls ldp

[PE1] interface vlanif 11
[PE1-Vlanif11] mpls
[PE1-Vlanif11] mpls ldp
[PE1-Vlanif11] quit
# Configure the basic MPLS function on ASBR-PE1 and enable LDP on the interface connected
to PE1.
<ASBR-PE1> system-view
[ASBR-PE1] mpls lsr-id 2.2.2.9
