Example for Configuring PW APS-protected Static VPWS SS-PW Accessing L3VPN (IP RAN Scenario)

This section provides an example for configuring a static VPWS PW with PW APS protection on the L2VPN side to access an L3VPN.

Networking Requirements

This chapter applies only to the NetEngine 8000 F1A.

To enable an Ethernet base station (NodeB) to communicate with a base station controller (RNC) on an IP RAN, you can configure L2VPN accessing L3VPN. Specifically, you can create a VE group consisting of one L2VE interface and one L3VE interface on each ASG and use the L2VE interface to terminate the L2VPN and the L3VE interface to access the L3VPN. In addition, you can configure PW APS on the CSG and ASGs to protect static PWs and configure VPN FRR to protect L3VPN services. Figure 1 shows a simplified single-ring network.

This example uses Virtual-Ethernet interface to configure L2VPN accessing L3VPN. As a VE interface is bound to only one board, when the board is faulty, services are interrupted. To improve service reliability, create two global virtual interfaces: Global-VE1 and Global-VE2. Global-VE1 is configured as an L2VE interface to terminate L2VPN services, and the Global-VE2 is configured as an L3VE interface to access an L3VPN network. Other configurations remain unchanged

  • In this example, interface1 and interface2 represent GE0/1/0 and GE0/1/3, respectively.

Configuration Roadmap

The configuration roadmap is as follows:

  1. Configure IP addresses on each device.
  2. Configure IGP routes on each device.
  3. Configure MPLS and public network tunnels. Specifically:
    • Configure a static bidirectional co-routed LSP between the CSG and ASG1, between the CSG and ASG2, and between ASG1 and ASG2.
    • Configure LSPs between ASGs and RSGs.
  4. Configure static VPWS on the CSG and ASGs.
  5. Configure PW APS on the CSG and ASGs.

  6. Configure an L3VPN.

    • Configure VPN instances on ASGs and RSGs.
    • Configure a VE group on each ASG, and bind the L3VE sub-interface in the group to the VPN instance on each ASG.
    • Establish MP-IBGP peer relationships between ASGs and RSGs.
    • Import direct routes to VPN instances on ASGs and RSGs.
    • Configure VPN FRR.

Data Preparation

To complete the configuration, you need the following data:

  • Interface numbers, interface IP addresses, and OSPF process IDs

  • L2VCs' destination IP addresses, VC IDs, and VC types

  • Names, local discriminators, and remote discriminators of BFD sessions

  • VE group number

  • Numbers and priorities of VRRP groups

Procedure

  1. Configure IP addresses for the CSG, ASGs, and RSGs. For configuration details, see Configuration Files in this section.
  2. Configure an IGP on the CSG, ASGs, and RSGs. In this example, OSPF is used.
