Packet Tracer – Troubleshooting GRE

Scenario A junior network was hired to set up a GRE tunnel between two sites and was unable to complete the task. You have been asked to correct configuration errors in the company network.

Part 1: Find and Correct All Network Errors. Device

Error

Correction

RA

Conflict ip address with tunnel 0

Remove ip from tunnel and then enter ip at interface G0/0/0

RB

Tunnel 0 source in on interface G0/0

Change source to interface s0/0/0

RB

Destination for tunnel 0 is incorrect

Change destination to 209.165.122.2

RA

Wrong ip route of ip address of next hop

Change ip address of next hop to 192.168.1.2

Part 2: Connectivity Step 1: Ping PCA from PCB. Attempt to ping the IP address of PCA from PCB. The ping should be successful.

Step 2: Trace the path from PCA to PCB. Attempt to trace the path from PCA to PCB. Note the lack of public IP addresses in the output.
