[j-nsp] DHCP option 82 under "forwarding-options helpers bootp" configuration

[Martin T]

Hi,

JUNOS(10.4R9.2 at M10i) supports DHCP relay agent information option
configuration under "forwarding-options helpers bootp". However,
despite the configuration, DHCP messages received by DHCP server do
not have option 82 present. For example I made such configuration:

root at labM10i> show configuration forwarding-options helpers bootp
dhcp-option82 {
    circuit-id {
        use-vlan-id;
    }
    remote-id {
        use-string test;
    }
    vendor-id {
        test;
    }
}
description "helpers bootp test";
server 10.10.10.1;
interface {
    ge-1/2/0.5;
}

root at labM10i>

..and executed dhclient in a broadcast domain associated with
interface ge-1/2/0.5. Packet capture results on a 10.10.10.1 DHCP
server can be seen here: http://cloudshark.org/captures/e963f493caf8
As you can see, there is no option 82 added.


Is it possible to add DHCP option 82 to messages forwarded to DHCP
server under "forwarding-options helpers bootp" configuration? Or is
this possible only with "dhcp-relay"? Latter would make more sense as
this option should be strictly DHCP
option(http://tools.ietf.org/html/rfc3046) not the BOOTP option?
