Hi all

Some parts of my research require some knowledge of RSVP-TE and MPLS. I
have a simple question and I appreciate if you can give me some idea or
link so that I can read the right draft or RFC.

My questions is

If there is an existing LSP established by RSVP-TE. Now, some segments
of the link have to be changed as shown as follows:

a---> b--->c to a--->b--->d

my question is that is there anyway we don't have to tear down the old
path, I mean the label from a-->b doesn't have to be changed? Is that
something allowed in RSVP-TE? 

Thank you very much,
