How to configure two sub-options with same code in .conf

[Songtao Li]

Hello.

I encapsulate two IPv6 address into DHCPv6 option 17 (D6O_VENDOR_OPTS) with two sub-options which have the same code=1 for them.

Here is the two sub-options in D6O_VENDOR_OPTS which I get from Wirshark:

        option
            Option code: 1
            Option length: 16
            Option data: fd12ac8b3f43006a98c5dbfffeba918b
        option
            Option code: 1
            Option length: 16
            Option data: 20010db80001000d0000000000001000

 

And I try to get the two IPs from dhclient. I configure the dhclient.conf to define the vendor-encapsulated-options for the IP.

Here is my definition in dhclient.conf:

       option space iplist code width 2 length width 2;
       option iplist.ctip code 1 = ip6-address;
       option vsio.iplist code 43793 = encapsulate iplist;

 

My problem is I alway get only one IP from dhclient when I using "require iplist.ctip;". Could anyone tell me how to configure dhclient to get both of the two IPs?

 

Thank you.

I’m guessing, but here’s something to try while waiting for an
expert answer.

Option length: 32
Option data:
fd12ac8b3f43006a98c5dbfffeba918b20010db80001000d0000000000001000
