[Dnsmasq-discuss] Configuring DHCPv6 Vendor specific information using Option 17

[P, Sreelakshmi]

Thanks Simon, this works!

In case of DHCP v4 vendor option, it's not mandatory to provide encapsulated vendor specific information. Here in DHCPv6, I see that the option 17 doesn't work without giving enterprise ID for encapsulation. Why so?

Also, is there a way to give hex as vendor option value that can include enterprise ID as well?

Regards,
Sree

You need something like

--dhcp-option=vi-encap:47196,option6:100,\
"AOS-Switch:Top:Tokyo,3ffe:501:ffff:100::abcd,aruba123"


Check the vendor-specific option number. I got the value of 100 from the data you provided, but I may have decoded it wrong.

Cheers,

Simon.
