The local zoo needs your help with their OSPF network. Since a recent animal breakout the security department decides all routing protocols need authentication. You decide to implement OSPF authentication in any way you can.
Goal:
All IP addresses have been preconfigured for you.
Configure OSPF on all routers. Achieve full connectivity. Ensure area 2 is directly connected by using a virtual link.
Configure MD5 authentication for Area 0. Do not use any interface commands to activate it.
Configure plaintext authentication in Area 1. Use interface commands to achieve this.
Configure MD5 authentication for the virtual link.

When configuring md5 authentication without assigning an authentication-key at the interface level - The ospf packet contents is NOT encrypted the OSPF header gets an Auth Type = Cryptographic but the LSA's are sent in clear text.
Hi Rene - yeah it's that exact statement that I feel is a little misleading as you cannot configure MD5 authentication without configuring it at the interface level.
Thanks alot for your hard work with this site and the labs - I'm prepping for ROUTE and fine them excellent in that regard.
No worries. I'm trying to create tasks that look a bit similar to Cisco exams or the way you get questions at the CCIE exam. It's better to have questions where people have to think about the solution instead of just telling them what to do (or so I hope/believe ;D)
