Example for Configuring a Local VPLS Connection
Context
In Figure 1, sites of an enterprise at different geographical locations connect to a PE on an ISP network through CE1 and CE2. To simplify the configuration, the enterprise requires that the two CEs communicate with each other like on a LAN. In this situation, the PE functions like a Layer 2 switch to directly transmit packets without using any public network tunnel.
Configuration Roadmap
Configure VLANs and IP addresses for interfaces.
Configure basic MPLS functions and enable MPLS L2VPN on the PE.
Create a virtual switch instance (VSI) on the PE and bind the VSI to interfaces. To implement a local VPLS connection, CE1 and CE2 must be bound to the same VSI.
Procedure
- Configure VLANs and IP addresses for interfaces.
# Configure CE1. The configuration of CE2 is similar to the configuration of CE1.
<HUAWEI> system-view [HUAWEI] sysname CE1 [CE1] vlan batch 10 [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
# Configure the PE.
<HUAWEI> system-view [HUAWEI] sysname PE [PE] vlan batch 10 20 [PE] interface loopback 1 [PE-LoopBack1] ip address 1.1.1.9 255.255.255.255 [PE-LoopBack1] quit [PE] interface gigabitethernet 0/0/1 [PE-Gigabitethernet0/0/1] port link-type trunk [PE-Gigabitethernet0/0/1] port trunk allow-pass vlan 10 [PE-Gigabitethernet0/0/1] quit [PE] interface gigabitethernet 0/0/2 [PE-Gigabitethernet0/0/2] port link-type trunk [PE-Gigabitethernet0/0/2] port trunk allow-pass vlan 20 [PE-Gigabitethernet0/0/2] quit
- Configure basic MPLS functions and enable MPLS L2VPN on the PE.
[PE] mpls lsr-id 1.1.1.9 [PE] mpls [PE-mpls] quit [PE] mpls l2vpn [PE-l2vpn] quit
- Create a VSI on the PE and bind the VSI to interfaces.
# Create an LDP VSI.
[PE] vsi abc static [PE-vsi-abc] pwsignal ldp [PE-vsi-abc-ldp] vsi-id 1 [PE-vsi-abc-ldp] quit [PE-vsi-abc] quit
# Bind the VSI to interfaces.
[PE] interface vlanif 10 [PE-Vlanif10] l2 binding vsi abc [PE-Vlanif10] quit [PE] interface vlanif 20 [PE-Vlanif20] l2 binding vsi abc [PE-Vlanif20] quit
- Verify the configuration.
# After the configuration is complete, run the display vsi verbose command on the PE. The command output indicates that the local VPLS connection has been set up for the VSI named abc and the VSI is in Up state.
