Example: Connecting a Logical System to a Physical Router

Requirements

PICs must be installed on the two routers.

Overview

In this example, Logical System LS1 is configured on Router R1. The Logical System LS1 has a direct connection to Router R2.

Figure 1 shows the topology used in this example.

Configuration

CLI Quick Configuration

To quickly connect a logical system to a physical router, copy the following commands into a text file, remove any line breaks, and then paste the commands into the CLI.

Step-by-Step Procedure

To connect a logical system to a physical router:

1. On Device R2, configure the interface to Logical System LS1.

   [edit]user@R2# set interfaces so-0/0/2 description R2->LS1 user@R2# set interfaces so-0/0/2 unit 0 family inet address 10.0.45.1/30

2. On Router R1, configure the interface.

   [edit]user@R1# set interfaces so-0/0/2 description "main router interface to R2"

3. On Router R1, configure the Logical System LS1 interface.

   [edit]user@R1# set logical-systems LS1 interfaces so-0/0/2 unit 0 description LS1->R2 user@R1# set logical-systems LS1 interfaces so-0/0/2 unit 0 family inet address 10.0.45.2/30

4. If you are done configuring the devices, commit the configuration.

   [edit]user@host# commit

Verification

Confirm that the configuration is working properly.

Verifying Connectivity

Purpose

Make sure that the devices can ping each other.
