RB1100AH ethernet bypass not working after shutdown

Tested with 6.15 and 6.19 - after "/system shutdown" the ethernet bypass is not activated, power has to be physically disconnected. I can hear the relay clicks on power up/down and while rebooting, but not when system is halted (even though ethernet ports are disabled, no more link).

Re: BGP session over 31 bit subnet

I've had similar issues with OSPF as well, between Mikrotik and Vyatta. The only common method supported by both is the old school /30 (wasting precious IPv4 addresses) - /31 works with Vyatta but not Mikrotik, /32 works with Mikrotik but not Vyatta.

so why are they not fully supported?
