Dialer Profiles
Dialer profiles were introduced into the IOS to offer design flexibility in
DDR networks. They are key to the function of dialer interfaces. Dialer pro-
files are based on separate logical interface configurations being bound to
physical interfaces. They involve configuring a profile, which is kept sepa-
