This provides a root object identifier from which experimental mibs may be temporarily based. mibs are typicially based here if they fall in one of two categories 1) are IETF work-in-process mibs which have not been assigned a permanent object identifier by the IANA. 2) are internal work-in-process which has not been assigned a permanent object identifier typicially because the mib is not ready for deployment. NOTE WELL: support for mibs in the tnExperimental subtree will be deleted when a permanent object identifier assignment is made.
