Hi
I have 2 routers and 2 switches and just practicing on it
R1
R2
SW1
SW2
R1 is connected to R2 thru a serial connection back to back cable
R1 has SW1 on it ethernet port
R2 had SW2 on it ethernet port
R1 E0/0 is up and up
SW1 FA0/1 is up and up
same with R2 and SWI2
My problem is R1 Cannot ping SW1 management ip address 1.1.1.2 and the same case is with R2 to SW2
There is connectivity between the serial interfaces and i can ping them
I have attached the Sh run output of the four devices
Please help
