Hi Stefan,
I'm not so sure if it is okay to modify the backbone configuration,
most likely not allowed in the Lab exam. I guess the challenge of the
task is to still be able to have full reachability to those routes
without modifying the config. There is a similar lab like this in IEWB
Vol I. The solution is to use NAT with overload.
