JUNOSe 11.0.x Broadband Access Configuration Guide
To maintain flexibility, the redirection response may include idle time or session
attributes that are considered as default unless the redirected authentication server
overrides them. For example, if the RADIUS server returns the VR context along with
an idle timeout attribute with the value set to 20 minutes, the router uses this idle
timeout value unless the RADIUS server configured in the VR context returns a
different value.
Since the router supports the RADIUS User-Name attribute [1] in the RADIUS response
message, the default VR RADIUS server may override the user's name (this can be
a stripped name or an entirely different name). Overriding is useful for the case when
the user enters a login name containing a domain name that is significant only to
the RADIUS server in the default VR.

IP Hinting

You can allocate an address before authentication of PPP sessions. This address is
included in the Access-Request sent to the authentication server as an IP address
hint.

Mapping a User Domain Name to a Virtual Router
Use to map a user domain name to a virtual router or a loopback interface.
When you specify only the domain name, the command sets the mode to Domain
Map Configuration.
Example
host1(config)#aaa domain-map juniper.net vrouter_1
host1(config)#aaa domain-map none vrouter_all_purpose
host1(config)#aaa domain-map default vrouter_all_purpose
host1(config)#aaa domain-map 8005558934 vrouter_78
host1(config)#aaa domain-map westford.com
host1(config-domain-map)#
Use the no version to delete the map entry.
See aaa domain-map
Use to preallocate an IP address for the remote B-RAS user before authenticating
the remote user.
The address is passed as a hint in the authentication request.
Example
host1(config-domain-map)#ip-hint enable
Use the no version to disable the feature.
