Example for Configuring an L2TPv3 Tunnel to Carry Services

An L2TPv3 tunnel supports multiple types of service access modes.

Networking Requirements

On the network shown in Figure 1, an L2TPv3 tunnel needs to be established between PE1 and PE2, and between PE1 and PE3. Services need to access the L2TPv3 tunnel between PE1 and PE2 in S-tag+C-tag mode and access the L2TPv3 tunnel between PE1 and PE3 in whole-interface mode. A VLAN service needs to be configured on CE1.

An L2TPv3 tunnel supports the following service access modes: whole-interface mode, C-tag termination mode, S-tag termination mode, and S-tag+C-tag termination mode. The L2TPv3 tunnel configurations for different service access modes are similar.

Configuration Roadmap

The configuration roadmap is as follows:

  1. Configure IS-IS routes on PEs.

  2. Configure the VLAN service on each CE.

  3. Enable L2TPv3 on each PE.

  4. Establish an L2TPv3 tunnel between PE1 and PE2, and between PE1 and PE3. Then, configure the source and destination addresses, cookies, and L2TPv3 instances for the two tunnels.

  5. Configure services on PE1, PE2, and PE3 to access L2TPv3 tunnels.

Data Preparation

To complete the configuration, you need the following data:

  • IS-IS process ID on each PE
  • VLAN ID on each CE

  • Source interfaces, source and destination addresses, and IP addresses of directly connected interfaces between PEs

  • Cookie values for L2TPv3 tunnels

  • Service access modes for L2TPv3 tunnels

  • IDs of L2TPv3 instances to be bound to L2TPv3 tunnels

Procedure

  1. Configure IS-IS routes on each PE.
