Free CCNA Labs: Troubleshooting OSPF (Advanced and Intermediate) Exam Prep with Brian Gallagher
Troubleshooting Routing Protocols Part 2: OSPF (Advanced and intermediate options). Can you get 100% for this lab?
#CCNA #OSPF #FreeLabFriday
In this lab scenario, you will again take on the role of a Network Support Engineer for a Cisco Partner. One of your clients – Stark Industries has recently had their network upgraded and as part of the implementation have deployed OSPF and OSPv3 in preference to RIPv2 as the dynamic routing protocols to support their IP and IPv6 network implementations
A support ticket has just been received from Stark saying that there are problems accessing the Branch router networks 192.168.0.0 /64 and the Branch Server IP of 192.168.200.9 from the Central router from an IPv4 perspective. They also report that the Branch users are having problems accessing the Stark Central Server IP of 192.168.200.1. Internet connectivity is still a problem. Stark Industries have also recently added IPv6 to a portion of the network as a proof of concept scenario. The IPv6 network runs between the Central Router to the Branch router and Routers 5, 6, 7 and 8 should be running IPv6 as a proof of concept IPv6 network. The support team at Stark have asked for help identifying the problems with the IPv6 issues. The Branch router is unable to reach the Central Server IPv6 address of 2001:db8:c0a9:100::1/64 and the Central router is unable to connect to the Branch Server using 2001:db8:c0a9:200::9/64
You are the Network Engineer on duty fielding this support request and it is your role to discover and remedy the issues in order to get both the IPv4 and IPv6 networks up and running again smoothly.
As part of your troubleshooting, you will have to gather information from multiple sources and analyze the information prior to proceeding with any possible plan to solve the problem, particularly as the IPv6 network has been added very recently. Once you have had time to digest all of the problems outlined in the ticket and gather the required information, you should implement the plan to rectify the problem. Once you have observed the network functioning normally again, document the solution and inform the customer.
