Hello Experts,

I have configure a default route to our ISP, see configs.

However, I'm unable to see the default route with command ip route.

Any thoughts?

Cheers

Carlton

You probably have another conflicting default route configured and the router is not injecting your new route into the routing table.

Check the routes and remove any conflicts

Is this your intended default route?
 ip route 0.0.0.0 0.0.0.0 xx.xx.xx.177
if not, remove this route and add the correct one
no ip route 0.0.0.0 0.0.0.0 xx.xx.xx.177

If you however plan to keep it in your config. You can prepend an AD value higher than 1 at the end
eg
ip route 0.0.0.0 0.0.0.0 xx.xx.xx.177 20

no ip source-route
no ip routing
!
!
no ip cef

Of course that there's no default route, there's no routing at all
:)
That's way show ip routing - shows nothing.

Predrag,

Well spotted.

The problem is when I issue the command ip routing I lose my telnet connection to interface 0/0

Can you help with that?

I don't think I can help you. There are dark forces on your router that do their work. :)
I saw similar config first time few days ago, and I don't understand it.

similar config

ip default-gateway 192.168.170.1
ip route 0.0.0.0 0.0.0.0 xx.xx.xx.177
You may be able to achieve the desired result just by replacing the default gateway address, 192.168.170.1 with x.x.x.177

ip route 0.0.0.0 0.0.0.0 x.x.x.x is the binary notation for default gateway.

Also
IP routing usually is on by default unless someone disabled it.
It's possible it's an IOS limitation.
You can try updating the IOS on your router and try again
