I am bit new to cisco and i am learning CCNA.
i have 3 routers with a switch and pc connected to the switch.
i am working on RIP and i enabled it on all routers and i am able to ping all interfaces/devices (2950 switch, 2500 & 2600 routers)
my current connection looks like this
PC---Switch(2950)---Router2(2610)---Router1(2500)---Router3(2610)--- Cable/Dsl Router(D-Link)--Cable modem
i can ping from PC to Router3's both interfaces but soon as i try to ping the Cable/Dsl Router or any external ip i get request timed out.
on my router3 f/e0 is connected to the Cable/DSL switch port.
The thing is from router3 i can ping external ip and the cable/dsl router. (i think i am missing out on something !!!)
