l VSI name and VSI ID
l IP addresses of peers and tunnel policy used for setting up the peer relationship
l Interfaces to which the VSI is bound
l Encapsulation mode of the sub-interfaces and VLANs that the sub-interfaces belong to
Procedure
Step 1 Configure the VLANs that the interfaces belong to according to Figure 5-11.
The configuration procedure is not mentioned.
NOTE
l The AC-side physical interface and PW-side physical interface of a PE cannot be added to the same
VLAN; otherwise, a loop occurs.
l After the configuration, the packets sent from a CE to a switch should contain a VLAN tag.
Step 2 Configure the IGP protocol. OSPF is used in this example.
When configuring OSPF, advertise the 32-bit loopback interface addresses (LSR IDs) of PE1,
P, and PE2.
The configuration details are not mentioned here.
After the configuration, run the display ip routing-table command on PE1, P, and PE2. You
can view the routes learned by PE1, P, and PE2 from each other.
Step 3 Configure basic MPLS functions and LDP.
The configuration procedure is not mentioned.
After the configuration, run the display mpls ldp session command on PE1, P and PE2. You
can see that the peer relationship is set up between PE1 and P, and between P and PE2. The
status of the peer relationship is Operational. Run the display mpls lsp command, and you can
see the status of the LSP.
Step 4 Create remote LDP sessions between PEs.
# Configure PE1.
[PE1] mpls ldp remote-peer 3.3.3.9
[PE1-mpls-ldp-remote-3.3.3.9] remote-ip 3.3.3.9
[PE1-mpls-ldp-remote-3.3.3.9] quit
# Configure PE2.
[PE2] mpls ldp remote-peer 1.1.1.9
[PE2-mpls-ldp-remote-1.1.1.9] remote-ip 1.1.1.9
[PE2-mpls-ldp-remote-1.1.1.9] quit
After the configuration, run the display mpls ldp session command on PE1 or PE2, and you
can find that the status of the peer relationship between PE1 and PE2 is Operational. That is, the
peer relationship is set up.
Step 5 Enable MPLS L2VPN on PEs.
# Configure PE1.
[PE1] mpls l2vpn
# Configure PE2.
