Description (partial)

interface-ID and remote-id dhcp options are not used by BNG when presented in the dhcpv6 solicit.
they are used when inserted via relay-message.

interfaceID can be used and relayed already via ddts un-30263 in XR520

Following BNG config:

aaa attribute format USERNAME
 format-string length 253 "%s" dhcpv6-interface-id

policy-map type control subscriber IP_POLICY_BASIC
 event session-start match-first
  class type control subscriber DHCP do-until-failure
   10 activate dynamic-template IP_BASIC
   20 authorize aaa list default format USERNAME password xyz

if the relay forward info is present in the solicit is not used, resulting in an empty username string and the attribute is not included in the access-request
