Support for Redundant Logical Tunnel

date_range 20-Dec-24

You can configure two logical tunnels on two different line cards to create a redundant logical tunnel (RLT). This provides redundancy when there is a failure in the FPC. Pseudowire over RLT supports two members in active-standby mode. Only one member link is active and carrying traffic at any given time.

To create the RLT, configure a pair of redundant-logical-tunnel interface at the [edit chassis redundancy-group interface-type] hierarchy and include the logical tunnel interface in the redundancy group by configuring member-interface interface-name at the [edit interfaces interface-name redundancy-group] hierarchy level.

The following is a sample configuration for pseudowire RLT.

chassis {
    pseudowire-service {
        device-count 500;
    }
    redundancy-group {
        interface-type {
            redundant-logical-tunnel {
                device-count 10;
            }
        }
    }
}
interfaces {
    rlt0 {
        redundancy-group {
            member-interface lt-0/1/0;
            member-interface lt-0/1/1;
        }
    }
    ps0 {
        anchor-point {
            rlt0;
        }
    }
}
