Hello John,

In case of RSVP-TE, when the tunnel egress node receives the Path message
with SESSION_ATTRIBUTE object, the objects "Flags" field indicating "SE Style desired" 
flag bit set, then it SHOULD use the SE Style when responding with a Resv message.
Else, if the egress receives the Path message without Session Attribute 
object or Session Attribute Object with SE Style desired flag bit reset
then the egress should respond with  FF Style. 

In case of RSVP, it is based on the Receiver end Real Time Applications, 
where it is possible to change the existing reservation from FF to SE based on the
situation dynamically.

Refer: draft-ieft-mpls-rsvp-lsp-tunnel-07.txt, pg:47.

Thanks and regards,

Hello,

I have a question about reservation style in RSVP:

How does the receiver decide the reservation style?
Since the sender has no effect for the style.


Thanks,

John
