hi all, i am taking this para from this link
http://www.cisco.com/en/US/docs/ios/12_1/wan/configuration/guide/wcdfrely.html#wp1002096
"This command (Frame-relay interface-dlci) is typically used on subinterfaces; however, it can also be applied to main interfaces. The frame-relay interface-dlci command is used to enable routing protocols on main interfaces that are configured to use Inverse ARP. This command is also helpful for assigning a specific class to a single PVC on a multipoint subinterface"
i didnt understand the reason it gave for defining dlci on main interface ! if i dont give dlci on main interface still i am able to run all routing protocols so what is it trying to tell ?
Any help plz
