David, Using it like the way it is done in CR LDP has some advantages in some situations. I wonder why it has been prevented in RSVP. Is any work being proposed in this direction. Regards.

Instead, they require an LSR to compare the entire path of an ERO with the path of an FA-LSP, and use this to decide when an LSP should be tunneled through another. Personally, I would much rather use the CR-LDP mechanism, but that doesn't seem to be an option anymore. -- David |
