the need for overflow/underflow, but I also haven't had any issues with 
the amount of resignaling that results.  YMMV.

Other important stuff is running adaptive LSPs (to get make-before-break 
SE reservations and avoid double counting), and optimize timers (to avoid 
relying on auto-bw to clean up after link failures).

This rabbit hole runs pretty deep...
