Yakov,

I've modified the Errata to suggest extending the text slightly as follows:

   Section 6 says:

   Whenever the PLR has a backup path available, the PLR MUST set
   the "local protection available" flag.

   It should say:

   Whenever the PLR has a backup path available, the PLR MUST set
   the "local protection available" flag.  For example, if the PLR
   has determined to use a bypass tunnel and set up the necessary
   local forwarding state to be able to use it as a backup path,
   then that PLR has a backup path available.

Assuming that's ok with the WG, Adrian or I can approve it.

Regards,
Alia
