The value of vRtrPimRsvpPmsiCGrpSrcState indicates the state of this
PMSI (S,G).
If the S-PMSI is bound to a (C-S,G) on the ingress PE and if the PE
is allocating a RSVP PMSI, the state will be 'txJoinPending'. The
state will change to 'txJoined' when the (C-S,G) traffic is switched
over to the new S-PMSI.

the state will be 'rxNotJoined'. The state will be 'rxJoined' if the
(C-S,G) has bound to the S-PMSI.
