What is cktMcastParentGroups?

This 8-byte encoded value lists which multicast group or groups this DLCI has been added to as a member, letting the admin look at any individual unicast circuit and determine which broadcast groups it currently participates in -- the reverse lookup from cktMcastGroupId. For example, an admin trying to understand why a particular branch's PVC is receiving traffic it didn't request would check cktMcastParentGroups on that DLCI's circuit entry to discover it was inadvertently added as a member of group 5 during a previous multicast configuration change.
