Thanks. Senthil.

In the quadruple (Src, Dst, Tunnel, LSP-id) you mentioned, the Src can be
provided either by Extended Tunnel ID field or Tunnel Sender Address field.

Can I use one of the two fields as a FEC for a host address since there
isn't a FEC element in RSVP-TE?

BTW, I read that guys of fast reroute or route protection are redefining the
Tunnel Sender Address.

Regards,
Bin
