Description

This article explains how to configure a vlan-bridge domain on ACX5448 devices with the help of an example. Such a configuration would be useful when customers want to use the ACX5448 device as only a Layer 2 device for specific link connections or VLANs.

 

Solution

Topology

 

The following topology consists of two peer network devices with ACX5448 as the L2 device in between.

Configuration on ACX2200-1

unit 0 {
    vlan-id 10;
    family inet {
        address 1.1.1.2/30;
    }
}
 

Configuration on ACX2200-2

  
labroot@jtac-ACX2200dc-r2002-re0> show configuration interfaces xe-0/3/0 
vlan-tagging;
unit 0 {
    vlan-id 10;
    family inet {
