Wait for your instructor before you proceed to the next part.
Part 3: Configuring Interfaces and Verifying Operational State
In this lab part, you will perform interface configuration and verify the operational state of interfaces using the Junos CLI.
Step 3.1
Enter configuration mode and load the lab2-part3-start.config file from the /var/home/lab/ijos/ directory. Commit you configuration when complete.
lab@srxA-1> configure Entering configuration mode
[edit]
lab@srxA-1# load override ijos/lab2-part3-start.config load complete
[edit]
lab@srxA-1# commit commit complete
[edit] lab@srxA-1#
Step 3.2
Refer to the network diagram for this lab and configure the listed interfaces. Use logical unit 0 on all specified interfaces. Commit the configuration and return to operational mode when complete.
[edit]
lab@srxA-1# edit interfaces
[edit interfaces]
lab@srxA-1# set ge-0/0/3 unit 0 family inet address address/30
[edit interfaces]
lab@srxA-1# set ge-0/0/2 unit 0 family inet address address/30
