Hi Rajneesh,

Thanks for your reply.

I have a slightly different interpretation on the mplsInterfaceLabelMinIn object. When looking at the descriptions in the mib, I understand that the mplsInterfaceLabelMinIn object is the minimum label value on an interface - be at a label from the local or the global label space.

After all, the description of the mplsInterfaceLabelMinIn object states the following:
        If only the
        perPlatform(0) bit is set, then the value of
        mplsInterfaceLabelMinIn, mplsInterfaceLabelMaxIn,
        mplsInterfaceLabelMinOut, and
        mplsInterfaceLabelMaxOut for this entry must be
        identical to the instance of these objects with
        index 0."

So this text indicates that the global label space also needs to be taken into account for the mplsInterfaceLabelMinIn object.

Best regards,

        Francis.

I had a similar problem while implementing this MIB few months back and I decided that we should give label range for RSVP and statically signalled LSPs (which was per interface as in your case).  LDP label range could be obtained from LDP MIB.  Please correct me if I am wrong.

Hello Tom et all, 

I have a question on the mplsInterfaceConfTable in the mpls lsr mib. IAssume that we consider the following: 
* Per interface label space used for RSVP signalled LSPs and static LSPs. 
* Global label space used for LDP signalled LSPs. 

Which value should we then give to the mplsInterfaceLabelMinIn: 
* The min label value of the per interface label space (that is, the min label value from the RSVP signalled LSPs and the static LSPs)? 
* The min label value of the RSVP signalled LSPs. 
* The min label value of all LSPs on the interface (=min of all LDP signalled, RSVP signalled and static LSPs). 

I would appreciate any help you can give me. 

Kind regards, 

        Francis.
