Example for Configuring the PWE3 Ping Test on a Single-Hop PW

Networking Requirements

In Figure 1, CE-A and CE-B are connected to PE-A and PE-B respectively. PE-A and PE-B are connected through the MPLS backbone network. A dynamic PW needs to be set up between PE-A and PE-B through the LSP tunnel.

The PWE3 Ping function of the single-hop PW needs to be performed to test the connectivity of the PW between PE-A and PE-B.

Figure 1 Networking diagram for configuring the PWE3 Ping test on the single-hop PW

Configuration Roadmap

The configuration roadmap is as follows:

Run the IGP protocol on the backbone network to make the routes between Switches on the backbone network reachable.
Configure the basic MPLS functions on the backbone network and set up an LSP tunnel. Set up the MPLS LDP peer relationship between the two PE devices on the two ends of the PW.
Create an MPLS L2VC connection between the two PE devices.
Configure a PWE3 Ping test on the single-hop PW on PE-A.

Procedure

Configure a dynamic single-hop PW.
Configure a dynamic single-hop PW on the MPLS backbone network. For the detailed configuration procedure, see PWE3 Configuration in the S2720, S5700, and S6700 V200R019C10 Configuration Guide - VPN.

Configure a PWE3 Ping test of the single-hop PW.

# Configure PE-A.

Perform the test.
```
[PE-A-nqa-test-pwe3ping] start now
```

Verify the test result.

After running the display nqa results command on the PE device, you can see that the test is successful.
