Hello Tom,
I realized that the cost of E1 (or N1 routes) would increase as the
route travels thru the OSPF domain, but my question is that at Router
1.1.1.1, shouldn't the metric of the OSPF type 1 route be 164 as well,
instead of 100??
Or is it the case where only the cost for the Routing Table is updated,
but not on the OSPF database??
I'm still a bit confused, and I would be greatly appreciated if you
could shed some light on this.
Thanks so much for your help in advance,
Best Rgards,
Hunt Lee
