Using DNIS

The E-series router supports dialed number identification service (DNIS). With DNIS, if users have a called number associated with them, the router searches the domain map for the called number. If it finds a match, the router uses the matching domain map entry information to authenticate the user. If the router does not find a match, it searches the domain map using normal processing.

Note: For DNIS to work, the router must be acting as the LNS. Also, the phone number configured in the aaa domain-map command must be an exact match to the value passed by L2TP in the called number AVP (AVP 21).

For example, as specified in the following sequence, a user calling 9785551212 would be terminated in vrouter_88, while a user calling 8005554433 is terminated in vrouter_100.

host1(config)#aaa domain-map 9785551212 vrouter_88
host1(config)#aaa domain-map 8005554433 vrouter_100
