I have a setup..
R1---(isis level 1 only)---R2---level 2 only)---R3
I have done the minimum, most required config. NO default route..
Cisco website says "Packets destined for an address that is outside of the L1 area are routed to the closest L1/L2 router to be forwarded on to the destination area."
If thats true I shud see a default route on R1 towards R2 ?
