DEFAULT ROUTING

AIM To make Default Routing between computers in the network.

PROCEDURE

1)    Create a topology using 3 Routers, 3 Switches and 6 Computers

2)    Configure IP address to routers go to global configuration mode in R0, R1 and R2 configure connected interfaces

3)    Assign IP address for both Pc's with appropriate IP and subnet mask and default gateway

4)    Configure Routers with Default Routing

5)    Double click PC move to desktop then command prompt give the command ping
