Chuck,
The command "ip routing" is on by default and hidden from the configuration.
Take two routers and configure them with just ip addresses. Then place a
loopback on R1. Place a default static route on R2 and ping the loopback on
R1. You will be able to ping successfully even though there are no routing
protocols running on R1.
Configs:
R1
interface loopback 0
ip address 2.2.2.2
!
interface ethernet 0
ip address 1.1.1.1 255.0.0.0
R2
interface ethernet 0
ip address 1.1.1.2 255.0.0.0
You actually need to turn off IP routing in global config or in a bridge
command (IRB, etc.).
