Procedure
Step 1 Configure the VLANs that interfaces of CEs, PEs and P belong to according to
assign IP addresses to VLANIF interfaces.
Packets sent from CEs to PEs carry a VLAN tag.
The configuration procedure is not mentioned.
Step 2 Configure an IGP on the MPLS backbone network. In this example, OSPF is used.
When configuring OSPF, advertise the 32-bit addresses of loopback interfaces on PE1, P, and
PE2. The loopback interface addresses are the LSR IDs.
The configuration procedure is not mentioned.
After the configuration, OSPF relations are established between PE1, P, and PE2. Run the
display ospf peer command, and you can see that the status of the OSPF relations is Full. Run
the display ip routing-table command, and you can view that the PEs can learn the routes of
their Loopback1 interfaces.
Step 3 Configure basic MPLS functions and LDP on the MPLS backbone network.
# Configure PE1.
[PE1] mpls lsr-id 1.1.1.9
[PE1] mpls
[PE1-mpls] quit
[PE1] mpls ldp
[PE1-mpls-ldp] quit
[PE1] interface vlanif 20
[PE1-Vlanif20] mpls
[PE1-Vlanif20] mpls ldp
[PE1-Vlanif20] quit
# Configure P.
[P] mpls lsr-id 2.2.2.9
[P] mpls
[P-mpls] quit
[P] mpls ldp
[P-mpls-ldp] quit
[P] interface vlanif 20
[P-Vlanif20] mpls
[P-Vlanif20] mpls ldp
[P-Vlanif20] quit
[P] interface vlanif 30
Issue 01 (2011-07-15)
Use the default tunnel policy to create an LSP and configure the LSP as the tunnel for data
transmission.
Enable MPLS L2VPN and create VC connections on the PEs.
Configure the Dot1q sub-interface to access the VLL on the interface connecting the PE
and CE.
Name of the remote peer of each PE
