Hi,
Ah, that's something I should also consider as well, thanks Brian!
As far as I can remember, the question in that lab also require you not to
use any access-list method to achieve the goal.
So if the worst case E0 to E1 also count as transit traffic, then I can't
think out another option other than "eigrp stub receive-only" with .. I am
not sure, polly NAT? in order to achieve the goal and still provide the full
reachability for that subnet behind sw2.
Cheers~
Jacky
