Wanted to followup. With the help of our server team we figured out how to make it work -

Here is what the config looks like to get the IP phones to have the tftp server-

First:
option space cisco code width 2 length width 2 hash size 17;
option cisco.tftp-servers code 1 = array of ip6-address;
option vsio.cisco code 9 = encapsulate cisco;

Then:
subnet6 x:y:z::/64 {
#  VOIP

authoritative;
option cisco.tftp-servers  server:v6:address::#1, server:v6:address:#2;
range6 x:y:z::;
}

The SSO SAML issue was resolved with the idp xml file, needed to remove 2 of the 3 root certs that were in the file. CUCM can not process cert's with more then one cert in the file, Must be 1 at a time for roots and CA files.

Hello,

Is anyone doing ISC IPv6 DHCP with Cisco IP Phones? If so What does your configs look like for the DHCP server to send the tftp server address? This would be similar to the v4 option 150.

How about Shibboleth as your iDP for SAML SSO?

Any ideas would be great!

Warm Regards,
