Procedure
Step 1 Configure the VLAN to which each interface belongs according to
The configuration details are not mentioned here.
Step 2 Configure an IGP on the backbone network.
Devices on the MPLS backbone network can interwork through an IGP. IS-IS used as an IGP
in this example.
The configuration details are not mentioned here. Note that IS-IS must be enabled on Loopback1.
After the configuration, IS-IS neighbor relationships are established between ASBR-PEs and
PEs in the same AS. Run the display isis peer command, and you can view that the neighbors
are Up. Run the display ip routing-table command, and you can view that ASBRs and PEs can
learn loopback addresses from each other.
Take PE1 as an example.
<PE1> display isis peer
System Id
0000.0000.0002
Total Peer(s): 1
<PE1> display ip routing-table
Route Flags: R - relied, D - download to fib

Configure an IGP on the backbone network to implement the connectivity between ASBR-
PEs and PEs and set up tunnels between PEs.
Establish MP IBGP peer relationships between PEs and ASBR-PEs in the same AS.
Configure VSIs on PE1, ASBR-PE1, ASBR-PE2, and PE2 and bind the VSIs to related
AC interfaces.
IS-IS data
MPLS LSR IDs of PEs and ASBR-PEs (IP addresses of the loopback interfaces on peers)
CE IDs and CE ranges
IP addresses of interfaces connecting CEs to PEs (No IP address is required for interfaces
connecting PEs to CEs.)
NOTE
Do not add the AC-side port and PW-side port of a PE to the same VLAN; otherwise, a loop may occur.
