Connectivity Issue

[spaceage21]

I have a cable modem connected in router g0/0 receiving dhcp and g0/1 internal lan connect to switch. I am able to ping the outside world from router but not switch and can't figure out what's wrong. Please Help

Could you post your config?

It could be so many things.

Thanks for the help Philip, its appreciated. Attached is the router configuration.

Enable IP routing in the device. I see this command in the output:

 --More--         no ip routing
no ip cef

+1 to Cisco Freak.  You need to enable routing.

ip routing

[spaceage21]

Thanks guys. When I enable ip routing I am no longer able to ping the internet. What happened?

[Philip D'Ath]

Did you try rebooting the router after saving the config?

Which model router are you using and what software version?

[spaceage21]

Yes, rebooted after enabling ip routing and saving the config. The model router is 2911 v15.0

[Cisco Freak]

can you share 'sh ip route' output?

Seems like the gateway config is wrong:

Gateway of last resort is 0.0.0.0 to network 0.0.0.0.

Can you please try this:

no ip route 0.0.0.0 0.0.0.0 GigabitEthernet0/0
ip route 0.0.0.0 0.0.0.0 47.32.79.122

[spaceage21]

when I try to run the last command it rejects and says invalid next ho address (its this router)

[spaceage21]

for some reason I am able to ping from the switch and a client now. All I did was attempt to run the cmd's above which the last one failed so disabling ip route fixed the issue?

[spaceage21]

Thanks again guys, everything is working now and I'm excited. Salute

My bad.. :)

Router is showing the proper error message..

What I meant is to use the IP address of the ISP side as your gateway.. :)

ip route 0.0.0.0 0.0.0.0 47.32.79.xxx
