Emulating a WAN connection on Cisco Gear
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!
interface Serial0
no fair-queue
service-module t1 clock source internal
On router B, 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 (12.173.110.3) (255.0.0.0) and lastly issue a no shut to bring the interface up!
interface Serial0
no fair-queue
service-module t1 clock source line
