General Doubts ?

HI all

I have a few quick Queries

1. Whether RSVP is IP encapsulated or UDP encapuslated ? In some
implementation it is IP . Where does UDP comes into picture ?

2. In MPLS Ping, when there is no return LSP Path and the LSP is only
unidirectional. How does the MPLS Ping works ?

3.What will happen when a tagged traffic is received on a Access port ? Not
a Dot1q Tunnel Port, Whether it gets discarded or it gets passed ?
My observation is it gets discarded ? Can someone throw some light on this
?
