As part of a Lab setup I have 2 routers (R7 & R8) connected via serial (2Mbs). Each router then connects to switch2 (10Mbs). R8 is an ASBR as I am redistributing the connected network between R8 and the switch. I redistribute this network into OSPF using the default metric of 20 and metric-type 1.
I anticipated that the cost from R7 to this network would be (64 + 20) 84, however, the cost is 85 ???
The area between R7 & R8 is NSSA (i.e the serial network).
Any ideas ?
