In this simulation, you will be troubleshooting multiple eBGP neighbor peering issues, in order to successfully restore full connectivity for the Cyberdine Industries network. The Packet Tracer Assessment requires you to restore the network configuration for dual-homed eBGP configuration on the Cyberdine Industries HQ router as well as configure both ISP1, ISP2 and ISP3routers.

Cyberdine Industries client PCs 1–4require access to both and services as well as client PCs also require full access to be able to connect successfully to the ISP1 and ISP2 Servers ( and detailed in the network topology by hostname resolution as well as by IP addressing. You must ensure that the Client PCs have access to the required resources to fully restore the network and gain the successful 100% in the challenge.

You will ensure that the following is completed:

1. The HQ router is configured with a Dual-Homed eBGP configuration with ISP1 andISP2 routers. The HQ router has already advertised its directly connected networks into BGP using the appropriate mask option.

2. The HQ router should ensure that all users on the Branch LAN are able to successfully open and view the Web Servers mentioned above as well as provide the required pathways to the ISP1 and ISP2listed servers via hostname resolution.

3. Troubleshoot ISP1 and ISP2to successfully restore eBGP neighbors with the HQ andISP3 routers.

4. ISP1 and ISP2 should not create any further network advertisements. Both ISP have the required network statements in place. You are required to ensure the newly introduced summarised ISP1 and ISP2 Server networks (209.165.204.xx) can be successfully reached by the PC clients using the existing BGP summary network statements.

5. Ensure that PCs on the Branch LAN are able to connect and correctly resolve the Web Servers as well as the recently introduced ISP1 and ISP2 Servers via hostnames. The Packet Tracer assessment lab may take a few minutes to display the actual Web Server pages correctly instead of the standard Packet Tracer graphic when successfully connecting to the Web Servers connected to ISP3.

6. There is an extra challenge within this scenario as the ISP3 network Admin has forgotten the privilege exec password! You will need to access the ISP3 router another way in order to successfully troubleshoot the problems. No reload of ISP3 is allowed and no username/password combinations require reset. You should have enough information from this assessment file and connectivity to access ISP3 in order to restore the configuration. Just some lateral thinking needed for this one!

You will be able to Check Results for your score and use this as possible hints and tips as to what to check to get the 100% score. The Packet Tracer assessment file will grade you and point you to check certain conditions have been met to score this lab on. There are connectivity tests built into this lab to test connectivity from the Branch LAN PCs to the David Bombal and Livelabs3 Web Servers as well as test connectivity to the newly introduced ISP1 and ISP2 Servers (209.165.204.xx). As this is an assessment lab, a copy of the completed .pkt file has been provided for configuration comparison.

Good luck everyone–Go get that 100%!
