To enforce the second RADIUS lookup, the dialout profile name (pipe-pat-out in this
example) must be different from the name of the called device in the user profile. The
Ascend-Recv-Name attribute specifies the name of the called device, in this case pipe-pat.
In the following second-tier user profile, called party’s name is pipe-pat and the
receive-password is pass.
pipe-patUser-Password="pass"

Ascend-Route-IP=1"
You can disable the double RADIUS lookup by naming the dialout profile with the peer’s
name and by omitting the Ascend-Recv-Name attribute. Use the User-Name attribute to
rename the profile (in this case to pipe-pat):
pipe-pat-outUser-Password="ascend"
User-Name="pipe-pat",
Service-Type=Outbound-User,

Message sequence during an outgoing call using two RADIUS lookups
A call using two RADIUS lookups passes through the follow messaging sequence:
1 The MAX unit requests a dialout profile from RADIUS.
2 RADIUS sends the dialout profile to the MAX unit.
3 The MAX unit makes an ISDN call to the remote device.
4 The ISDN call is connected.
5 The MAX unit and the called party perform LCP exchanges.
6 The called party sends a challenge request to the MAX unit.
7 The MAX unit responds with a challenge response.
8 The called party informs the MAX unit about whether the first level of authentication has
been successful.
