This was set up in a lab enviroment using an Adtran Atlas 550 to simulate WAN connection. This will document configuring an ISDN BRI connection with dial-on-demand routing (DDO), RIP routing over ISDN, and B channel aggragation.

Configuring BRI

1. Basic Router Configuration
2. Configure the router to use the approiate ISDN switch types,

• This configuration uses the basic-ni switch type. To learn about the other switch type go to ISDN Switch Types
• Router(config)# isdn switch-type type

1. Use Dialer List to identifiy intresting traffic

• Router(config)# dialer-list dialer-group-number protocol protocol-name permit | deny | list access-list-numeber
