APPENDIX G - DHCP server requirements for ALIF support
Version 1.0
ALIF DHCP client
The ALIF DHCP client will identify itself to a DHCP server using DHCP option 60
(Vendor-Class-Identier) containing the brand string appropriate to the rmware, e.g.
Adder.
The ALIF DHCP client will also provide the DHCP server with its unique hostname and
a request for DHCP option 125 (Vendor Identied Vendor Sub Options).
DHCP server
A DHCP server will use the Vendor-Class-Identier to identify an ALIF and supply it with
Adder vendor information encapsulated in the Adder Enterprise number (25119) within
DHCP option 125 (Vendor Identied Vendor Sub Options).
As of ALIF rmware version 4.2, the required Adder vendor information to be
encapsulated is:
Sub-option 1: Array of IP addresses of all AIM servers in the cluster.
Note: ALIF will ignore any DHCP OFFER not containing this information.
Example Alpha (ISC DHCPd, Adder, AIM servers: 10.0.20.5, 10.0.20.6)
# ISC DHCPd conguration for Adder
set vendor-string = option vendor-class-identier;
option space adder code width 1 length width 1;
option adder.aim-servers code 1 = array of ip-address;
option space vivso code width 4 length width 1;
option vivso.iana code 0 = string;
option vivso.adder code 25119 = encapsulate adder;
option option-125 code 125 = encapsulate vivso;

max-lease-time 7200;

where:
0x0000621f Adder Enterprise number (25119)
0x0a Length
0x01 Sub-option 1
0x08 Length
0x0a001405 10.0.20.5 (Primary AIM)
