Purpose
The configurations in this topic are for the six routers in the example network illustrated in Figure 1.
Action
To display the configuration of a router, use the following JUNOS CLI operational mode command:

Meaning
Sample Outputs 1 through 6 show the configurations of all six routers in the example network illustrated in Figure 1. LSPs R1-to-R6 and R6-to-R1 are configured on R1 and R6, respectively.
Two static routes, 100.100.1/24 on R1 and 100.100.6/24 on R6, are configured at the [edit routing-options static route] hierarchy level. Both prefixes are included in the send-statics policy at the [edit policy-options send statics] hierarchy level so the routes can become BGP routes.
In addition, the RID is configured manually at the [edit routing-options] hierarchy level to avoid duplicate RID problems, and the passive statement is included at the [edit protocols isis interface lo0] hierarchy level to ensure that protocols are not run over the loopback (lo0) interface and the loopback (lo0) interface is advertised correctly throughout the network.
