Hi All,

1). In RSVP-TE while ingress say LER1 sends a path message to egress say
LER2 through say LSR1,LSR2,LSR3.
when PATH_MESSAGE reaches egress and now egress will send the
RESV_MESSAGE to the ingress.
During the transmission of RESV_MESSAGE lets say LSR2 goes down.Here my
question is whether LSR3 can 
re-route the path or ingress LER1 has to send a new PATH_MESSAGE to
egress LER2 to create a new path for
re-routing after time-out ?

2). In RSVP while using Shared Explicit STYLE where do we store the
information of the users which are using that 
shared reservation ?

3). In RSVP there are three possible LABEL_REQUEST types,what are the
ranges of Lable values for each type ?

TIA,
