Support for Redundant Logical Tunnel
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;
}
}
}
