Networking Requirements

As shown in Figure 1, CE1 and CE2 belong to the same VPN. They access the MPLS backbone network through PE1 and PE2 respectively. OSPF is used as the IGP protocol on the MPLS backbone network.

In this scenario, you need to configure Martini VLL. An MPLS TE tunnel must be established between PE1 and PE2 through the dynamic signaling protocol RSVP-TE to forward the traffic of the VLL. The bandwidth of the tunnel is 20 Mbit/s. The maximum bandwidth of the link that the TE tunnel passes through is 100 Mbit/s, and the maximum reservable bandwidth is 50 Mbit/s.

Figure 1 Networking diagram of configuring Martini L2VPN using MPLS TE tunnels 

Procedure

1. Configure an IP address for each interface and configure OSPF in the backbone network.
   The configuration details are not mentioned here.
2. Enable MPLS, MPLS TE, MPLS RSVP-TE, and MPLS TE CSPF.
   Enable MPLS, MPLS TE, and MPLS RSVP-TE in the system view and the interface view of each node along the tunnel, and enable MPLS TE CSPF in the MPLS view of the ingress of the tunnel.

5. Configure a tunnel interface.
   # Create the tunnel interface on the PEs, specify the tunnel protocol as MPLS TE and the signaling protocol as RSVP-TE, and specify the bandwidth.
   # Configure PE1.

6. Establish LDP sessions.
   Establish a remote peer session between PE1 and PE2.
   # Configure PE1.

   [PE1] mpls ldp

   [PE1-mpls-ldp] quit

   [PE1] mpls ldp remote-peer  3.3.3.9

   [PE2-mpls-ldp-remote-1.1.1.9] quit

   After the configuration, LDP sessions are established between the PEs.
   Take the display on PE1 as an example:

   [PE1] display mpls ldp session

   [CE2-Pos1/0/0] quit

   
   
8. Verify the configuration.
   Run the display mpls lsp verbose command on PE1. You can view that an MPLS RSVP-TE tunnel is established between 1.1.1.9 and 3.3.3.9. The LSP index of this tunnel is the same as the value in the MPLS forwarding table, which indicates that the local packets to 3.3.3.9 are forwarded through the MPLS TE tunnel.
