JUNOS 10.1 Network Interfaces Configuration Guide
Source routers A and B use loopback addresses as the prefixes to be monitored. Most

of the configuration tasks and actual monitoring occur on transit Router SCU.
Configuration
The loopback address on Router A contains the origin of the prefix that is to be
assigned to source class A on Router SCU. However, no SCU processing happens on
this router. Therefore, configure Router A for basic Open Shortest Path First (OSPF)
routing and include your loopback interface and interface
process.

Last, apply the policy to the forwarding table.
Router SCU
Router SCU handles the bulk of the activity in this example. On Router SCU, enable
source class usage on the inbound and outbound interfaces at the

specify the expected traffic: input, output, or, in this case, both.
Next, configure a route filter policy statement that matches the prefixes of the
loopback addresses from routers A and B. Include statements in the policy that
classify packets from Router A in one group named
Router B in a second class named
policy containing multiple terms.
