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.
