[j-nsp] Bypass LSP functionality question

[David Ball]

  Just looking for confirmation of a suspicion here.

  If I have an LSP configured with link-protection on every interface
along the way (creating many-to-one Bypass LSPs, as opposed to 1:1
detours), no secondary standby path defined, and a protected interface
fails, the ingress node will have no ability to perform a
make-before-break, right?  Because the Path Tear messages will be sent
both upstream and downstream from the failed interface?  The bypass
will only help me up until the upstream nodes process the Path Tears
and a new LSP is signalled from the ingress node....or am I missing
something?

  More familiar with detours, so just checking myself wrt bypasses....

Cheers,

David
