This is true. As the requirements state "full reachability" must be
obtained, you should do whatever is necessary to achieve that as long as the
general restrictions are not violated (i.e. no statics, ip policy routing)
etc. This may include injecting networks into IGP, BGP, redistributing
protocols, configuring NAT, etc. Whatever works and is the simplest answer.
