Examples: Configuring Intrachassis LSQ Redundancy

MLPPP Configuration

The following configuration shows that lsq-1/1/0 and lsq-1/3/0 work as a pair and the redundancy type is hot-standby, which sets the requirement for the failure detection and recovery time to be less than 5 seconds:

interfaces rlsq0 {
redundancy-options {
primary lsq-1/1/0;
secondary lsq-1/3/0;
hot-standby; #either hot-standby or warm-standby is supported
}
}

The following example shows a related MLPPP configuration:

Note: MLPPP protocol configuration is required for this configuration.

interfaces {
t1-/1/2/0 {
unit 0 {
family mlppp {
bundle rlsq0.0;
}
}
}
rlsq0 {
unit 0 {
family inet {
address 30.1.1.2/24;
}
}
}
}

The following example shows a related CoS configuration:

class-of-service {
interfaces {
rlsq0 {
unit * {
fragmentation-maps fr-map1;
}
}
}
}

The following example shows a complete link state replication configuration for MLPPP. This example uses two bundles, each with four T1 links. The first four T1 links (t1-*:1 through t1-*:4) form the first bundle and the last four T1 links (t1-*:5 through t1-*:8) form the second bundle. To minimize the duplication in the configuration, this example uses the [edit groups] statement; for more information, see the JUNOS System Basics Configuration Guide. This type of configuration is not required; it simplifies the task and minimizes duplication.
