Example: Configuring VPLS with BGP Signaling

date_range 23-Dec-19

This example shows how to configure VPLS with BGP signaling between two devices.

Requirements

Before you begin, see Understanding Selective Stateless Packet-Based Services .

Overview

This example shows a minimum configuration for PE devices and CE devices to create a VPLS network with BGP signaling. The topology consists of two PE devices and two CE devices. In this example, you configure a VPLS routing instance vpls-instance between two PE devices, PE1 and PE2. You also configure the CE1 and CE2 devices that use Ethernet-based interfaces to connect VLAN 600 to their local PE devices. On the CE1 device, configure the Fast Ethernet interface that connects to the PE1 device. The VLAN identifier and IP address must match those of the CE2 device.

Figure 1 shows the topology used in this example.

Configuring the CE1 Device

CLI Quick Configuration

To quickly configure this example, copy the following commands, paste them into a text file, remove any line breaks, change any details necessary to match your network configuration, copy and paste the commands into the CLI at the [edit] hierarchy level, and then enter commit from configuration mode.

set interfaces fe-0/0/3 vlan-tagging
set interfaces fe-0/0/3 unit 0 vlan-id 600
set interfaces fe-0/0/3 unit 0 family inet
address 10.11.3.1/24

Step-by-Step Procedure

The following example requires you to navigate various levels in the configuration hierarchy. For instructions on how to do that, see Using the CLI Editor in Configuration Mode.

Enable VLAN tagging on the VPLS interface.

[edit interfaces fe-0/0/3]
user@host# set vlan-tagging
Configure the VLAN ID on the logical interface.

[edit interfaces fe-0/0/3 unit 0]
user@host# set vlan-id 600
Configure the VPLS family on the logical interface.

[edit interfaces fe-0/0/3 unit 0]
user@host# set family inet address 10.11.3.1/24

Results

From configuration mode, confirm your configuration by entering the show interfaces command. If the output does not display the intended configuration, repeat the configuration instructions in this example to correct it.

content_copy zoom_out_map
fe-0/0/3 {
vlan-tagging;
unit 0 {
vlan-id 600;
family inet {
address 10.11.3.1/24;
}
}
}

If you are done configuring the device, enter commit from configuration mode.

Note

If VLAN trunking is not needed between the CE devices, remove the configuration on VLAN tagging on the interfaces connecting the CE and PE devices. Also, use ethernet-VPLS-encapsulation instead of vlan-vpls on the CE facing interfaces of the PE devices.

Verification

Confirm that the configuration is working properly.
