Hi,

 

Is there a way to add multiple vendor options in DHCPv6?

Hi,

 

I am looking to add vendor options in my dhcpv6 server.  I am able to add a single instance of vendor option. However I need to support multiple enterprises and need to add multiple vendor options for that as follows:

 

 

option dhcp6.vendor-opts

12:34:20:da:

00:01:00:04:

12:23:45:67;

 

option dhcp6.vendor-opts

12:35:20:da:

00:01:00:04:

12:09:45:89

 

However version 4.3.5 after applying the below patch, server is responding with the vendor option but only the last configured vendor option. It is ignoring other vendor options.

 

How can I make server to configure so that it sends back the data based on the received enterprise Id value in the request/solicit packet.

 

 

Regards,

Saurabh Jain

Hello:

There was an issue introduced in ISC DHCP 4.3.5 which broke the server's ability to send dhcp6.vendor-opts.  This
has been corrected in our upcoming feature release, 4.4.0, due out Q1/2018:

- The ability of the server to send back dhcp6.vendor-opts values has been
  restored. A change in 4.3.5 (see #29246) which enabled it to send back the
  FQDN option unfortunately broke its ability to send back dhcp6.vendor-opts.
  Thanks to Sumant Gupta (sumantgupta at gmail dot com) of Landis+Gry for
  bringing this issue to our attention.
  [ISC-Bugs #46427]

It will be included in our next maintenance release, 4.3.7, but it's date is TBD>

I have attached a patch which corrects the issue for 4.3.6.
