Virtual Private LAN Service (VPLS) delivers a point-to-multipoint L2VPN service over an MPLS or IP backbone. The provider backbone emulates a switch to connect all geographically dispersed sites of each customer network. The backbone is transparent to the customer sites. The sites can communicate with each other as if they were on the same LAN.

VPLS has the following networking models:

· Full mesh—Suitable for MPLS backbone networks with a simple architecture and fewer PEs. The following networking modes are available under this model:

¡ LDP—Uses the LDP protocol as the signaling protocol, suitable for scenarios with a small number of sites and the number of sites is fixed.

¡ BGP auto-discovery with LDP signaling—Uses the BGP protocol to automatically discover remote PEs, and then uses the LDP protocol as the signaling protocol, suitable for scenarios with many sites but the number of sites is fixed.

¡ BGP—Uses extended BGP as the signaling protocol, suitable for scenarios with a large number of sites and the need for expansion.

· H-VPLS—Suitable for MPLS backbone networks with a complex architecture and a large number of PEs. This model uses a hierarchical network structure that contains UPEs and NPEs. A UPE is responsible for customer site access and establishing connections with the nearest NPE, and NPEs are fully interconnected logically. UPEs exchange packets with remote sites through NPEs. The following networking modes are available under this model:

¡ LSP access—Packets are transmitted over an LSP tunnel, suitable for scenarios where UPEs support VPLS.

¡ QinQ access—Packets are encapsulated with an outer VLAN tag before being transmitted over an LSP tunnel, suitable for scenarios where UPE devices do not support VPLS.

Prerequisites

The configuration examples were created and verified in a lab environment, and all the devices were started with the factory default configuration. When you are working on a live network, make sure you understand the potential impact of every command on your network.

The following information is provided based on the assumption that you have basic knowledge of VPLS.

Restrictions and guidelines

Before you configure MPLS, you must change the device's operating mode by using the switch-mode command and restart the device for the following switches:

· S6812 series

· S6813 series

· S5560X-EI series

· S5560X-HI series

· S5500V2-EI series

· MS4520V2-30F

· MS4520V2-30C

· MS4520V2-54C

· S6520X-HI series

· S6520X-EI series

· S6520X-SI series

· S6520-SI series

· S5000-EI series

· MS4600 series

In a non-IRF environment, use the switch-mode 3 command to switch the device to MPLS mode.

In an IRF environment, use the switch-mode 4 command to switch the device to MPLS-IRF mode.

PEs do not transparently transmit LACP or LLDP protocol packets over a VPLS network.

If STP is globally enabled on a PE, the PE transparently transmits STP packets over the VPLS network only after you use the stp transparent enable command to enable BPDU transparent transmission on a port. For more information about the stp transparent enable command, see STP commands in Layer 2—LAN Switching Command Reference.

Example: Configuring full-mesh VPLS (LDP signaling)

Network configuration

As shown in Figure 1, a company has three offices in different locations: headquarters and two branches. The company requires the provider to offer a Layer 2 VPN service that interconnects the three offices at Layer 2, allowing them to share internal resources.

The company has few branches and will not expand further. To meet user requirements, configure LDP-based VPLS to enable communication between the three sites at Layer 2.

Figure 1 Network diagram

Analysis

· Deploy MPLS on the backbone network and use LSP as the public tunnel.

· Establish LDP PWs between the PEs for full-mesh VPLS.

· Configure a service instance and corresponding match rules on the downlink port of each PE device to identify packets from the customer network that require a VPLS tunnel for transmission.

· To achieve VLAN isolation between sites, create VSIs user_a and user_b and bind them to VLAN 100 and VLAN 200, respectively.

Example: Configuring full-mesh VPLS (BGP auto-discovery LDP signaling)

Network configuration

As shown in Figure 2, a company has multiple offices in different locations: headquarters and several branches. The company requires the provider to offer a Layer 2 VPN service that interconnects all offices at Layer 2, allowing them to share internal resources.

The company has many branches and will not expand further. To meet user requirements and reduce configuration and maintenance workload, use BGP auto-discovery LDP signaling to enable Layer 2 communication between all user sites.

Figure 2 Network diagram

Analysis

· Deploy MPLS on the backbone network and use LSP as the public tunnel.

· Configure and establish a BGP auto-discovery LDP signaling-based PW between any two PEs to achieve full mesh of PWs.

· Configure a service instance and corresponding match rules on the downlink port of each PE device to identify packets from the customer network that require a VPLS tunnel for transmission.

· To achieve VLAN isolation between sites, create VSIs user_a and user_b and bind them to VLAN 100 and VLAN 200, respectively.

Example: Configuring full-mesh VPLS (BGP)

Network configuration

As shown in Figure 3, a company has 10 data centers located in different geographical areas and plans to add 15 more data centers. The company requires the provider to offer Layer 2 VPN services, enabling all data centers to interconnect at Layer 2 and share data resources.

The company has many data center sites and requires large-scale expansion. To meet user requirements, deploy BGP-based VPLS services.

Figure 3 Network diagram

Analysis

· Deploy MPLS on the backbone network and use LSP as the public tunnel.

· Deploy BGP-based VPLS service on PEs and configure label blocks to meet expansion requirements.

· To achieve VLAN isolation between sites, create VSIs user_a and user_b and bind them to VLAN 100 and VLAN 200, respectively.

Example: Configuring H-VPLS (LSP access)

Network configuration

A provider provides VPLS service, with numerous users in various locations. To simplify the network structure and reduce device load and maintenance workload, deploy H-VPLS on the network.

As shown in Figure 4, make sure the following requirements are met:

· Branches at different locations connect to the carrier MPLS network through UPEs that support MPLS L2VPN.

· NPEs connect to the UPEs by using the LSP access mode.

· The UPEs are dual homed to two NPEs for increased reliability.

Figure 4 Network diagram

Device	Interface	IP address	Device	Interface	IP address
UPE 1	Loop0	11.1.1.1/32	UPE 2	Loop0	14.1.1.1/32
	Vlan-int10	11.1.2.1/24		Vlan-int12	20.1.1.1/24
	Vlan-int11	11.1.3.1/24		Vlan-int13	20.1.2.1/24
NPE 1	Loop0	1.1.1.1/32	NPE 3	Loop0	3.3.3.3/32
	Vlan-int10	11.1.2.2/24		Vlan-int13	20.1.2.2/24
NPE 2	Loop0	2.2.2.2/32	NPE 4	Loop0	4.4.4.4/32
	Vlan-int11	11.1.3.2/24		Vlan-int12	20.1.1.2/24

Analysis

· To negotiate the inner labels, establish remote LDP peer relationships between the UPEs and all connected NPEs, as well as between any two NPEs.

· On the UPEs, set up primary/backup peers to determine the primary and backup status of the links.

· Configure a service instance and corresponding match rules on the downlink port of each UPE identify packets from the customer network that require a VPLS tunnel for transmission.

· To achieve VLAN isolation between sites, create VSIs user_a and user_b and bind them to VLAN 100 and VLAN 200, respectively.

Procedure

Configuring basic network settings

1. Create interfaces for UPE and NPE devices as shown in Figure 4 and configure IP addresses for them. (Details not shown.)

2. Configure IGP on the MPLS backbone network to ensure that all interfaces on the NPEs and UPEs are reachable to each other. (Details not shown.)

3. Configure basic MPLS and MPLS LDP on the backbone network to establish LDP LSPs. (Details not shown.)

4. Configure interfaces on each CE that connect to UPEs as a trunk port and permit packets from VLAN 100 and VLAN 200 to pass through with tags. (Details not shown.)

Example: Configuring H-VPLS (QinQ access)

Network configuration

A provider provides VPLS service, with numerous users in various locations. To simplify the network structure and reduce device load and maintenance workload, deploy H-VPLS on the network.

As shown in Figure 5, make sure the following requirements are met:

· Branches at different locations connect to the carrier MPLS network through UPEs that do not support MPLS L2VPN.

· NPEs connect to the UPEs by using the QinQ access mode.

· The UPEs are dual homed to two NPEs for increased reliability.

Figure 5 Network diagram

Analysis

· On the downlink port of each UPE, configure QinQ for NPEs identify user traffic by outer label.

· Use STP to provide loop protection and redundancy for the links.

· On the downlink port of each NPE, configure service instances to match user packets by outer label to transmit user packets over the associated PW.

· To negotiate inner labels, establish remote LDP peer relationships between any two NPEs.

Configuring NPE 4

The configuration for NPE 4 is similar to that for NPE 3 except that the NPE peers for them are different. For more information about the configuration, see the configuration file.

Verifying the configuration

Verify the state of PWs on each NPE. The following uses NPE 1 as an example.

# Use the display l2vpn pw command on NPE 1 to view the PW state.

[NPE1] display l2vpn pw

Flags: M - main, B - backup, H - hub link, S - spoke link, N - no split horizon

Total number of PWs: 3, 3 up, 0 blocked, 0 down, 0 defect

VSI Name: user_a

Peer PW ID/Rmt Site In/Out Label Proto Flag Link ID State

2.2.2.2 500 131199/131199 LDP M 256 Up

3.3.3.3 500 131198/131198 LDP M 257 Up

4.4.4.4 500 131197/131197 LDP M 258 Up

# Use ping to identify whether hosts within the same VLAN but at different sites can reach each other. If the ping operation succeeds, the VPLS is created successfully.
