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. Set up
MPLS LDP peer relations between U-PE1 and S-PE, and between U-PE2 and S-PE.
3. Create a PW template. Enable the CW and LSP ping function.
4. Create an MPLS L2VC connection between the two U-PEs.
5. Create a switching PW on the switching node S-PE.
6. Configure the basic BFD capability and trigger the dynamic BFD for PW on U-PEs.
Data Preparation
To complete the configuration, you need the following data:
l IP addresses of the interfaces, including VLAN interfaces and VLANIF interfaces
l LSR IDs of the devices
l VC-ID of the PW
l BFD parameters
Procedure
Step 1 Configure the IDs of the VLANs to which the interfaces of CE, PE, and P belong according to
Figure 6-18.
Step 2 Assign an IP address to the VLANIF interface connecting the CE to the PE.
The configuration procedure is not mentioned.
Step 3 Configure an IGP protocol on the MPLS backbone network.
Configure an IGP protocol on the MPLS backbone network. OSPF is used as the IGP protocol
in this example.
Configure interface addresses of the U-PE, S-PE, and P. When configuring OSPF, note that the
32-bit loopback interfaces of U-PE1, S-PE, and U-PE2 must be advertised.
# Configure U-PE1.
[U-PE1] interface loopback 0
[U-PE1-LoopBack0] ip address 1.1.1.9 32
[U-PE1-LoopBack0] quit
[U-PE1] interface vlanif 20
[U-PE1-Vlanif20] ip address 10.1.1.1 24
[U-PE1-Vlanif20] quit
[U-PE1] ospf 1
[U-PE1-ospf-1] area 0.0.0.0
[U-PE1-ospf-1-area-0.0.0.0] network 10.1.1.0 0.0.0.255
[U-PE1-ospf-1-area-0.0.0.0] network 1.1.1.9 0.0.0.0
[U-PE1-ospf-1-area-0.0.0.0] quit
[U-PE1-ospf-1] quit
# Configure P1.
[P1] interface loopback 0
[P1-LoopBack0] ip address 2.2.2.9 32
[P1-LoopBack0] quit
