Procedure
Step 1 Configure the IDs of the VLANs to which the interfaces belong according to
The configuration procedure is not mentioned.
Step 2 Configure an IGP protocol on the backbone network.
PEs and ASBR-PEs on the MPLS backbone network can communicate with each other by using
IGP. OSPF is used as the IGP protocol in this example.
The configuration procedure is not mentioned. Note that the address of Loopback1 must be
advertised to the IBGP peer.
After the configuration, the ASBR-PE and the PEs in the same AS can learn the Loopback1
addresses of each other. Run the display ip routing-table command, and you can see that the
ASBR and the PEs in the same AS can learn the Loopback1 addresses of each other.
Take the display on PE1 for example.
<PE1> display ip routing-table

The ASBR-PE and the PEs in the same AS can ping each other's Loopback1 address.
<PE1> ping 2.2.2.2

Issue 01 (2011-07-15)
Establish an IBGP adjacency between the PE and the ASBR-PE in an AS.
Set up a Kompella VLL connection between the PE and the ASBR-PE in an AS.
OSPF data
MPLS LSR-IDs of PE and ASBR-PEs
L2VPN instance name, RD, and VPN target on the PE and the ASBR-PE
CE connection name, CE ID, CE range (10 by default), and default offset (1 or 0, the default
is 0) on the PE and ASBR-PEs
