Configuration Roadmap
The configuration roadmap is as follows:
1.
Run an IGP protocol on the devices of the backbone network to implement connectivity.
2.
Configure the basic MPLS functions on the backbone network and set up an LSP.
3.
Set up a remote LDP session between the U-PE1 and S-PE.
4.
Create a static or dynamic MPLS L2VC connection between the two U-PEs.
5.
Create a switching PW on the S-PE.
Data Preparation
To complete the configuration, you need the following data:
l
L2VC IDs on U-PE1 and U-PE2 (the L2VC IDs should be different)
l
MPLS LSR-IDs of U-PE1, S-PE, and U-PE2
l
VC label of the static PW on U-PE2 (pay attention to the mapping between the VC labels
on the two ends)
l
Encapsulation type of the PW
l
Name and attributes of the PW template used on U-PE2
Procedure
Step 1
Configure interface addresses for CE, U-PE,P and S-PE according to
, including
VLAN and VLANIF interfaces.
The configuration procedure is not mentioned.
Step 2
Configure an IGP protocol on the MPLS backbone network.
The OSPF protocol is used in this example.
Configure addresses of the VLANIF interfaces on the U-PE, S-PE, and P according to
. When configuring OSPF, note that the 32-bit loopback interfaces of U-PE1, S-PE, and U-
PE2 must be advertised.
The configuration procedure is not mentioned.
Step 3
Enable MPLS on U-PE1 and S-PE. Set up a tunnel and a remote LDP session between U-PE1
and S-PE.
Configure basic MPLS functions and tunnels on the MPLS backbone network. In this example,
the LSPs are configured as tunnels.
You need to set up a remote LDP session between U-PE1 and S-PE.
