Hello: can someone let me know what numbered / unnumbered routing means? and also what does it mean to "assign a WAN IP Address on your Serial Interface". When I get a block of ip address I will have to configure my router to have a WAN / LAN interface IP address - I have done this in the past. I am getting a new T1 line for my facility and the provider has asked me this question:

"Do you need numbered routing? (WAN IP Address on your Serial Interface). Please note that we typically do not assign an IP address to the Serial WAN, but rather use IP unnumbered"

and I am not sure what he means by this. Can someone explain this to me pls? Thank you.

numbered routing is when you have assinged IP addresses to your interfaces and are routing traffic to specific IPs
unnumbered routing is when you do not assign IP addresses to your interfaces and are routing traffiic to specific interfaces...

Unnumbered routing only works on point-to-point links... traffic going in one end of the link simply comes out the other end without the need of IP addresses since there are only two devices on that link... your router and the ISPs router... there is no need for numbered routing. Its used as an IP address conservation technique.

When using unnembered routing you'll use interface names as gateways instead of IPs in your routing table.
