2. Configure basic MPLS functions on devices in the backbone network and establish dynamic
LSPs between PEs and ASBR-PEs in the same AS. Establish remote LDP sessions if PEs
and ASBR-PEs are indirectly connected.
3. Establish VPLS connections between PEs and ASBR-PEs in the same AS.
Data Preparation
To complete the configuration, you need the following data:
l IS-IS data
l IP addresses of remote peers
l MPLS LSR IDs on PEs and ASBR-PEs
l VSI IDs
Procedure
Step 1 Configure the VLAN to which each interface belongs according to Figure 6-9.
The configuration details are not mentioned here.
NOTE
The S9300 only allows the CE to access the PE through a trunk.
Do not add the AC-side port and PW-side port of a PE to the same VLAN; otherwise, a loop may occur.
Step 2 Configure an IGP on the MPLS backbone network.
PEs and ASBR-PEs on the backbone network can interwork by using an IGP.
In this example, IS-IS is used, and the configuration details are not mentioned here.
After the configuration, the IS-IS neighbor relationship is established between ASBR-PEs and
PEs in the same AS. Run the display isis peer command, and you can view that the status of
IS-IS neighbors is Up, and the PEs can learn loopback addresses from each other.
Take the display on PE1 as an example.
<PE1> display isis peer

ASBR-PEs and PEs in the same AS can ping each other successfully.
Take the display on PE1 as an example.
