regarding dhcpv6 option 68

[Bill Shirley]

What does "its not working" mean?  It doesn't get a lease?  It gets the wrong lease?

Looks like your 'match if' is incorrect.  It should be *substring (/data-expr*, /offset*, /length*). */*/*/*Can you try:
   match if substring*(**v6relay(1, option dhcp6.vss)*, *1*, *5**)*= "test1";
