For IPv6 subscriber hosts, RADIUS-triggered mid-session changes and session terminations may identify the subscriber host to be changed by the same address or prefix that was originally returned from RADIUS. Only one address attribute (framed-IP address, framed-IPv6-prefix, delegated-IPv6-prefix or Alc-IPv6-address) may be provided in a single request.
For PPPoE clients, changing either the IPv4 or IPv6 information results in both the v4 and v6 subscriber host being modified (if they are contained within the same PPPoE session).
The only CoA action that is allowed for IPv6 hosts is a change of ESM strings; creation of new hosts and forcing a DHCPv6 RENEW is not supported.
