I am trying a lab with this topology:
in the exercise I am asked to set up OSPF between R1,2 and 3 and Router 4,5 and 6, easy enough.
The lab then asks me this:
-Configure a default route on R1 to R4 using the next hop address as argument
-Configure a default route (last resort) to the ISP
Now, I was under the impression that default route and last resort, were just two names to describe the same thing. Now however I am puzzled on how should I go about doing that.
I can't obviously set a single default route towards the internet as I do need a way to make the networks behind the router communicate between them, is using static routes to make the routers learn of the networks behind them and then just use a last resort that points to the ISP the way to go or, I am missing something more obvious?
