Networking Requirements
As shown in Figure 1, two routers, PE1 and PE2, are PEs to be enabled with the VPLS function. CE1 is connected with PE1, while CE2 is connected with PE2. CE1 and CE2 belong to the same VPLS. After the VPLS configuration, interworking between CE1 and CE2 is available.
In the network, construct a VPLS VPN for CE1 and CE2 and adopt the LDP as the VPLS signaling to establish the PW.
Configuration Roadmap
The configuration roadmap is as follows:
-
Configure the routing protocol on the backbone network.
-
Set up the remote LDP session between PEs.
-
Set up the tunnel used to transmit the user data between PEs.
-
Enable the MPLS L2VPN on the PE.
-
Create the VSI on the PE. Specify the signaling as LDP and then bind the VSI with the AC interface.
Data Preparation
To configure the Martini VPLS, you need the following data:
-
VSI name and VSI ID
-
IP address and tunnel policy used in setting up the peer
-
Interface bound to the VSI
Procedure
- Configure OSPF.
Configure the IP addresses of the PE and P as shown in Figure 1. When configuring OSPF, configure OSPF to advertise the 32-bit address of the loopback interface (LSR-ID) of the PE1, P and PE2.After the configuration, run the display ip routing-table command on PE1, P and PE2. The output shows that PE1 and PE2 know each other’s routing information.For the details on the configuration of the OSPF in this instance, see the following Configuration Files.
- Configure basic MPLS capability and LDP.
For the detailed procedure of the configuration, see the following Configuration Files.Run the display mpls ldp session command on PE1 and PE2, and you can see that LDP sessions are established between the peers. Run thedisplay mpls lsp command, and you can see the information of established LSPs.
- Configure remote session of LDP.
# Configure PE1.
[PE1] mpls ldp remote-peer 3.3.3.9
[PE1-mpls-ldp-remote-pe2] remote-ip 3.3.3.9
[PE1-mpls-ldp-remote-pe2] quit
# Configure PE2.[PE2] mpls ldp remote-peer 1.1.1.9
[PE2-mpls-ldp-remote-pe1] remote-ip 1.1.1.9
[PE2-mpls-ldp-remote-pe1] quit
After the configuration, run the display mpls ldp session command on PE1 or PE2, and you can find the status of the peers PE1 and PE2 is “operational”. That is, the remote peer relationship is set up. - Enable MPLS L2VPN on PEs.
# Configure PE1.
[PE1] mpls l2vpn
# Configure PE2.[PE2] mpls l2vpn
- Configure a VSI on each PE.
# Configure PE1.
[PE1] vsi a2 static
[PE1-vsi-a2] pwsignal ldp
[PE1-vsi-a2-ldp] vsi-id 2
[PE1-vsi-a2-ldp] peer 3.3.3.9
# Configure PE2.[PE2] vsi a2 static
[PE2-vsi-a2] pwsignal ldp
[PE2-vsi-a2-ldp] vsi-id 2
[PE2-vsi-a2-ldp] peer 1.1.1.9
- Bind the VSI with the AC interface on PE.
# Configure PE1.
[PE1] interface gigabitethernet1/0/0.1
[PE1-GigabitEthernet1/0/0.1] shutdown
[PE1-GigabitEthernet1/0/0.1] vlan-type dot1q 10
[PE1-GigabitEthernet1/0/0.1] l2 binding vsi a2
[PE1-GigabitEthernet1/0/0.1] undo shutdown
# Configure PE2.[PE2] interface gigabitethernet2/0/0.1
[PE2-GigabitEthernet2/0/0.1] shutdown
[PE2-GigabitEthernet2/0/0.1] vlan-type dot1q 10
[PE2-GigabitEthernet2/0/0.1] l2 binding vsi a2
[PE2-GigabitEthernet2/0/0.1] undo shutdown
- Configure the CEs.
# Configure CE1.
<HUAWEI> sysname CE1
[CE1] interface gigabitethernet1/0/0.1
[CE1-GigabitEthernet1/0/0.1] shutdown
[CE1-GigabitEthernet1/0/0.1] vlan-type dot1q 10
[CE1-GigabitEthernet1/0/0.1] ip address 10.1.1.1 255.255.255.0
[CE1-GigabitEthernet1/0/0.1] undo shutdown
# Configure CE2.<HUAWEI> sysname CE2
[CE2] interface gigabitethernet1/0/0.1
[CE2-GigabitEthernet1/0/0.1] shutdown
[CE2-GigabitEthernet1/0/0.1] vlan-type dot1q 10
[CE2-GigabitEthernet1/0/0.1] ip address 10.1.1.2 255.255.255.0
[CE2-GigabitEthernet1/0/0.1] undo shutdown
- Verify the configuration.
After the configuration, run the display vsi name a2 verbose command on PE1, and you can see that VSI named a2 establishes a PW to PE2 and the VSI is Up.

vsi command is not working on any router which came by default with simulator
what is the solution
