This article discusses the solutions for quiz 14 and it describes some scenarios to help understand why redistributing iBGP into IGP (OSPF in this case) is dangerous.

Your network follows a standard 3 tier hierarchical design (Core, Distribution, Access) and has two WAN circuits with eBGP sessions with the ISPs. You want to push the default route down to the Distribution routers, but something goes wrong. Where is the mistake?

Your company has 2 offices that are interconnected via a firewall (Cisco ASA) as shown below. You received the task to configure a BGP session between the border routers but something does not go according to plans.

Your company has more offices and each of them has a separate internet connection. The default route for each office points towards the ISP. Also, within each office you run iBGP using private AS numbers. You try to establish a BGP session between two offices, but the BGP does not come up. Why ?
