None in my mind. The legacy network operator was unfamiliar with actual best practice enterprise/carrier networking policies that he thought that for BGP to work on a two internet feed network, both internet connections have to be delivered to the same location. I thought since he has more insight into Mikrotik, that he knew about a bug with Mikrotik that made the argument true. Feedback from NANOG list members that also run Mikrotik has proven that there is no problem with running current rev levels of the Mikrotik RouterOS and BGP with internet feeds at two different locations.
