Doubts about MPLS-TE Mib

Hi ,

I have a few doubts about the MPLS-TE Mib.
Please note that the doubts are with regards to usage of RSVP-TE as the
signalling mechanism .

1. There are three similar objects in the mplsTunnelTable ....
mplsTunnelIndex , mplsTunnelInstance , mplsTunnelPrimaryInstance  .
 According to my understanding , mplsTunnelIndex is the same as the TunnelId
in the Session object .
 But how does mplsTunnelInstance and mplsTunnelPrimaryInstance fit into
RSVP-Te ?
 Are they outside the scope of RSVP-Te ?
 Or do they refer to LspIds of primary and secondary Lsps ? 

2. the object mplsTunnelIngressId is defined to be used as the
ExtendedTunnelId .
 But then where will the SenderTemplate object's Sender IP address come from
?

3. What is the difference between ARHopTable and CHop Table ?
   Do they refer to incoming and updated EROs ?

Thanks in advance
