1.
Run the IGP protocol on the backbone network to make the routes between Switches on
the backbone network reachable.
2.
Configure the basic MPLS functions on the backbone network and set up an LSP tunnel.
Set up MPLS LDP peer relations between U-PE1 and S-PE, and between U-PE2 and S-
PE.
3.
Create an MPLS L2VC connection between the two U-PEs.
4.
Create a switching PW on the switching node S-PE.
5.
Configure a PWE3 Trace test on the multi-hop PW on U-PE1.
Data Preparation
To complete the configuration, you need the following data:
l
L2VC IDs on U-PE1 and U-PE2, which must be different
l
MPLS LSR-IDs of U-PE1, S-PE, and U-PE2
l
IP address of the remote peer
l
Encapsulation type of the switching PW
l
Name and parameters of the PW template on U-PE devices
Procedure
Step 1
Configure a dynamic multi-hop PW.
Configure a dynamic multi-hop PW on the MPLS backbone network.
For the detailed configuration procedure, see "PWE3 Configuration" in the
Quidway S9300
Terabit Routing Switch Configuration Guide - VPN
.
Step 2
Configure a PWE3 Trace test of the multi-hop PW.
# Configure U-PE1.
<U-PE1>

Step 3
Perform the test.

Step 4
Verify the test result.
After running the
display nqa history
command on the PE device, you can see that the status
is
successful
