Title: One-Hop Ping
Difficulty: Medium (1 point).
Technical Description: Figure out why a ping from R1 to R2 is failing, and propose a way to fix the configuration.
For this challenge, you need to start the topology called: “ALGERIA – One-Hop Ping”.
In the Junosphere topology a plain one-hop ping from R1 to R2 is failing:
juniper@R1> ping 10.1.1.2
PING 10.1.1.2 (10.1.1.2): 56 data bytes
--- 10.1.1.2 ping statistics ---
1 packets transmitted, 0 packets received, 100% packet loss
You need to troubleshoot it. What is causing this ping to fail, and what in R1’s or R2’s configuration is triggering this behavior?
Although you actually don’t have access to the configuration, imagine for a moment that you were allowed to execute this procedure in either R1 or R2:
As a result:
- You would not change the IP addressing.
- You would make the plain ping above work, without any ping options.
To solve this challenge, what is the <command> and on which router would you execute the procedure?
