Dear All
My question bout IE
as we know thier is not layer 3 to layer 2 mapping from r5 to ar2 and also
from r4 to r2
so we can use routing protocol to make mapping
so can u please any body tell how this happened after I apply ospf to get
this result
162.1.0.0/24 is subnetted, 2 subnets
C 162.1.45.0 is directly connected, Dialer0
C 162.1.0.0 is directly connected, Serial0/0
150.1.0.0/16 is variably subnetted, 4 subnets, 2 masks
C 150.1.5.0/24 is directly connected, Loopback0
O 150.1.4.4/32 [110/65] via 162.1.0.4, 00:17:50, Serial0/0

how is r and 4 indicate 162.1.0.2 (R2 wan address ) as direct connect it
and also his route coming direct from 162.1.0.2
why r5 and r4 didnt go through r3 to reach r2 address and route
