Router Configurations for the INET Load-Balanced Network

Purpose

The configurations in this section are for the six routers in the example network illustrated in Figure 12.

Action

To display a router configuration, use the following JUNOS CLI operational mode command:

user@host> show configuration | no-more

Sample Output 1

The following sample output is for edge router R6:

user@R6> show configuration | no-more
