This works fine, (except for P2MP LSPs).

You also need to make sure that all links in the primary LSP has
link-protection on the interface.

And of course, there must be an alternate way to set up the bypass.

You don't need to configure the bypass LSP. It is set up
automatically.  The bypass command seems to allow you to set
constraints on your bypass LSP, put I have never used this, so I can't
help you with this one.
