Example for Configuring Point-to-Multipoint VPLS in Martini Mode
Networking Requirements
In Figure 1, an enterprise builds a backbone network and has three branch sites. Site1 connects to PE1 on the backbone network through CE1. Site2 connects to PE2 on the backbone network through CE2. Site3 connects to PE3 on the backbone network through CE3. Users at Site1, Site2, and Site3 need to communicate at Layer 2.
Configuration Roadmap
Configure VLANs and IP addresses for interfaces.
- Configure an IGP. In this example, OSPF is used.
- Configure MPLS LDP.
- Establish a remote MPLS LDP session.
- Configure Martini VPLS.
Procedure
- Configure VLANs and IP addresses for interfaces.
# Configure CE1. The configurations of CE2, CE3, PE1, PE2, and PE3 are similar to that of CE1.
<HUAWEI> system-view [HUAWEI] sysname CE1 [CE1] vlan 10 [CE1-vlan10] quit [CE1] interface vlanif 10 [CE1-Vlanif10] ip address 10.1.1.1 255.255.255.0 [CE1-Vlanif10] quit [CE1] interface gigabitethernet 0/0/1 [CE1-GigabitEthernet0/0/1] port link-type trunk [CE1-GigabitEthernet0/0/1] port trunk allow-pass vlan 10 [CE1-GigabitEthernet0/0/1] quit
The AC-side and PW-side physical interfaces of a PE cannot be added to the same VLAN; otherwise, a loop may occur.
- Configure OSPF on PE1, PE2, and PE3.
When configuring OSPF, advertise the 32-bit IP address of the loopback interface (LSR IDs) on PE1, PE2, and PE3.
# Configure PE1. The configurations of PE2 and PE3 are similar to that of PE1.
[PE1] interface loopback 1 [PE1-LoopBack1] ip address 1.1.1.9 255.255.255.255 [PE1-LoopBack1] quit [PE1] ospf 1 router-id 1.1.1.9 [PE1-ospf-1] area 0.0.0.0 [PE1-ospf-1-area-0.0.0.0] network 1.1.1.9 0.0.0.0 [PE1-ospf-1-area-0.0.0.0] network 168.1.1.0 0.0.0.255 [PE1-ospf-1-area-0.0.0.0] network 168.1.2.0 0.0.0.255 [PE1-ospf-1-area-0.0.0.0] quit [PE1-ospf-1] quit
After the configuration is complete, run the display ip routing-table command on PE1, PE2, and PE3. The command output shows that PE1, PE2, and PE3 have learned routes from each other.
- Configure basic MPLS functions and LDP on PE1, PE2, and PE3.
# Configure PE1. The configurations of PE2 and PE3 are similar to that of 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 [PE1] interface vlanif 30 [PE1-Vlanif30] mpls [PE1-Vlanif30] mpls ldp [PE1-Vlanif30] quit
# After the configuration is complete, run the display mpls ldp session command on PE1, PE2, and PE3. The command output shows that the Status field of the peer relationships between PE1, PE2, and PE3 is Operational, indicating that the peer relationships have been established. The following uses the command output on PE1 as an example.
[PE1] display mpls ldp session LDP Session(s) in Public Network Codes: LAM(Label Advertisement Mode), SsnAge Unit(DDDD:HH:MM) A '*' before a session means the session is being deleted. ------------------------------------------------------------------------------ PeerID Status LAM SsnRole SsnAge KASent/Rcv ------------------------------------------------------------------------------ 2.2.2.9:0 Operational DU Passive 0004:03:36 23906/23906 3.3.3.9:0 Operational DU Passive 0004:03:41 23928/23927 ------------------------------------------------------------------------------ TOTAL: 2 session(s) Found.
# After the configuration is complete, run the display mpls lsp command on PE1, PE2, and PE3 to check information about the established LSPs. The following uses the command output on PE1 as an example.
[PE1] display mpls lsp Flag after Out IF: (I) - LSP Is Only Iterated by RLFA ------------------------------------------------------------------------------- LSP Information: LDP LSP ------------------------------------------------------------------------------- FEC In/Out Label In/Out IF Vrf Name 1.1.1.9/32 3/NULL -/- 3.3.3.9/32 NULL/3 -/Vlanif30 3.3.3.9/32 1024/3 -/Vlanif30 2.2.2.9/32 NULL/1025 -/Vlanif30 2.2.2.9/32 1025/1025 -/Vlanif30 - Establish a remote LDP session between PEs.
# Configure PE1.

# Configure PE3.
[PE3] mpls ldp remote-peer 1.1.1.9 [PE3-mpls-ldp-remote-1.1.1.9] remote-ip 1.1.1.9 [PE3-mpls-ldp-remote-1.1.1.9] quit [PE3] mpls ldp remote-peer 2.2.2.9 [PE3-mpls-ldp-remote-2.2.2.9] remote-ip 2.2.2.9 [PE3-mpls-ldp-remote-2.2.2.9] quit
After the configuration is complete, run the display mpls ldp session command on PE1, PE2, and PE3. The command output shows that the Status of the peer relationships between PE1, PE2, and PE3 is Operational, indicating that the remote peer relationships have been established.
- Enable MPLS L2VPN on PEs.
# Configure PE1.
[PE1] mpls l2vpn [PE1-l2vpn] quit
# Configure PE2.
[PE2] mpls l2vpn [PE2-l2vpn] quit

- Bind the VSI to PE interfaces.
# Configure PE1.
[PE1] interface vlanif 10 [PE1-Vlanif10] l2 binding vsi company [PE1-Vlanif10] quit
# Configure PE2.
[PE2] interface vlanif 50 [PE2-Vlanif50] l2 binding vsi company [PE2-Vlanif50] quit
# Configure PE3.
[PE3] interface vlanif 60 [PE3-Vlanif60] l2 binding vsi company [PE3-Vlanif60] quit
- Verify the configuration.
# After the network becomes stable, run the display vsi name company verbose command on PE1. The command output shows that a PW to PE2 and a PW to PE3 have been established in the VSI named company, and the VSI status is Up.
