Make sure you also set the command "ip routing" in general configuration 
in order to "switch on" the ip route engine.
You won't see this setting on the config though.

In old versions this command was not implicit, funny though, what could 
I possibly want a router to do other than routing?
Perhaps it has something to do with old technologies routing which 
wasn't IP?

Hi Chloe,

When your configuration seems to be incomplete. When a router is facing 2
networks, there should be 2 distinct IP addresses in a router.

For example :

# faces your local lan
Ethernet 0/0
IP address 192.168.0.116 255.255.255.248

# faces your "external" network
Serial 0/0
IP address 10.0.0.1 255.255.255.252

Before you try to ping "across" different networks, make sure both links are
up locally first
(Eth0/0 must be pingable from 192.168.0.116 subnet, while S0/0 must be
pingable from 10.0.0.1 subnet)

After you can achieve this, then you can check out the routing tables by
typing
myrouter> *show ip route*
