Section: 6

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

Corrected Text
--------------
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.

Notes
-----
In the case of facility-based FRR the PLR must set the "local protection available" flag if it has the bypass tunnel available and the local forwarding state is set up.
