Basic Rate Interface (BRI)
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
- Basic Router Configuration
- 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
- Use Dialer List to identifiy intresting traffic
- Router(config)# dialer-list dialer-group-number protocol protocol-name permit | deny | list access-list-numeber
- Configure BRI Interface with encapsulation and authentication settings
- Router(config)# interface interface-number
- Router(config-if)# ip address ip-address subnet-mask
- Router(config-if)# encapsulation ppp
- Router(config-if)# ppp authentication chap
- Congigure a service profile identifier (SPID)
- Router(config-if)# isdn spid spid-number local-dial-number
- Set the Dialer Idle Timeout
- The dialer idle timeout defualts to 120 seconds. It may need to be changed to a lower value to avoid excesive call charges.
- Router(config-if)# dialer idle-timeout seconds
- Associate the interface to the already created dialer-list
- Router(config-if)# dialer-group dialer-group-number
- Configure the Dialer Map
- The dialer map tells the interface what to do with interesting traffic
- You do not need to enable broadcasts if your routing protocol does not need broadcast.
- The dial string is the destination telephone number.
- Router(config-if)# dialer map protocol next-hop-address name hostname [broadcast] dial-string
