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.

aaa domain-map

• 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.

ipv6-local-interface
