Configuration Roadmap
The configuration roadmap is as follows:
1. Configure the routing protocol on the backbone network to implement interworking.
2. Set up a remote LDP session between the PEs.
3. Establish a VPLS full mesh between PEs,
4. Configure MSTP. Configure PE1 and PE2 as the primary roots, and configure PE3 and
PE4 as the secondary roots.
Data Preparation
To complete the configuration, you need the following data:
l VSI name and VSI ID
l IP addresses of peers and tunnel policy used for setting up the peer relationship
l Interfaces to which the VSI is bound
l Encapsulation mode of the sub-interfaces and VLANs that the sub-interfaces belong to
l STP region name and priority
NOTE
When associating VPLS with MSTP, you can bind a dot1q sub-interface, QinQ sub-interface, or VLANIF
interface to a VSI. Dot1q sub-interfaces are used in this example.
Procedure
Step 1 Configure the VLAN to which each interface belongs according to Figure 9-10.
The configuration procedure is not mentioned.
NOTE
l Do not add AC-side physical interface and PW-side physical interface of a PE to the same VLAN;
otherwise, a loop occurs.
l Packets sent from the CEs to the PEs must contain VLAN tags.
Step 2 Configure the IGP protocol. OSPF is used in this example.
When configuring OSPF, advertise 32-bit loopback interface addresses (LSR IDs) of PE1, PE2,
PE3, and PE4.
The configuration procedure is not mentioned.
After the configuration is complete, run the display ip routing-table command on PE1, P, and
PE2. You can view the routes learned by PE1, P, and PE2 from each other.
Step 3 Configure basic MPLS functions and LDP.
The configuration procedure is not mentioned.
After the configuration, run the display mpls ldp session command on PE1, P and PE2. You
can see that the peer relationship is set up between PE1 and P, and between P and PE2. The
status of the peer relationship is Operational. Run the display mpls lsp command. You can view
the information about the established LSP.
Step 4 Create a remote LDP session between PEs.
