Hi Brian
Actually I have the question related to this
In the Internetork book and many other documents for this scenario and
similar ones (where the other routing protocol is RIP or EIGRP with existing
external routes)
preferred solution seems to be filtering using tags.
However this doe not provide the redundancy .
My question is if redundancy was not mentioned anywhere in lab requirements
is it safe do filtering (match easier) and not to provide any redundancy ?
thanks
Nenad
