I have two Cisco 2611 routers and I have two Cisco 1721 routers, This will work with a wide variety of Cisco router gear.
On router A, get to priv exec mode, and get to the first serial interface. Issue the commands below on that interface, also don’t forget a valid ip address, subnet mask (12.173.110.2) (255.0.0.0) and lastly issue a no shut to bring the interface up!
