Legacy DDR is a term used to define a very basic DDR configuration in which a single set of dialer parameters is applied to an interface. If multiple unique dialer configurations are needed on one interface, then dialer profiles should be used.

To configure legacy DDR perform the following steps:

• Define static routes
• Specify interesting traffic
• Configure the dialer information
