Bob,

You are perfectly true, but in this case there is actually a bug in the 
mib which is kind of confusing. Indexes SHALL always be "not-accessible", 
see section 7.7 in RFC1902. Making them "accessible-for-notify" breaks 
the SMI for SNMPv2 and upsets my compiler (although it's recoverable). 

The reason I guess is to include the objects in the notifications, but 
including auxiliary objects in notifications are cosidered bad practice
(exept for that it violates SMI) since the objects have the same value as
the OID itself. 

So, Tom et.al 

The auxiliary objects mplsTunnelIndex, mplsTunnelInstance, 
mplsTunnelIngressLSRId, mplsTunnelEgressLSRId should be removed
from the notifications (their values are anyway carried in the 
mplsTunnelAdminStatus) and the objects should be made not-accessible
in the mplsTunnelTable. 

Else you won't get the mib through either a compiler nor IESG ;-)
