Data Preparation
To complete the configuration, you need the following data:

Procedure
Step 1 Configure IGP on the MPLS backbone of AS 100 and AS 200 respectively to make ASBR and
PE can reach each other in the same AS.
OSPF is used as the IGP in this example, the configuration procedure is not mentioned.
After the configuration, the OSPF neighbor relationship should be established between the
ASBR and the PE of the same AS. Run the display ospf peer command to find that the OSPF
neighbor relationship is in "Full" state.
The ASBR and the PE in the same AS can ping through each other and can learn the Loopback
interface address of each other.
Step 2 Configure MPLS basic capability and MPLS LDP on the MPLS backbone of AS 100 and AS
200 respectively to set up LDP LSP.
# Configure basic MPLS capability on PE1 and enable LDP on the interface connecting ASBR1.

Issue 01 (2012-04-20)
Create the VPN instance on two ASBRs and bind the instance to the interface connected
another ASBR. Set up the EBGP peer relationship between ASBRs
MPLS LSR-ID of the PE and the ASBR
The VPN instance names of the PE and the ASBR, RDs and the VPN-targets
NOTE
The 32-bit loopback interface address used as LSR ID should be advertised by OSPF.
