Agreed. Breaking about once a month or possibly even more frequently than that is what we started to see with one of our v3.30 BGP routers. This was after flawless performance for many, many months. This is why we initially felt it might be a hardware issue.
MikroTik Support response was simply to upgrade to current version (v4.11), so we did. That was about 50-60days ago I think? Since then the router hasn't had any trouble, so we're feeling pretty good about it. If it happens again or the hardware is/was the issue and it ultimately fails; we have an exact matching router racked up right beneath it ready to go. Eventually we may have Butch help us setup VRRP or some other method to tie the two routers together and keep both routers running all the time. We bring in multiple upstream GigE feeds from diverse geographical locations into our network, so losing a BGP router doesn't necessarily mean the network goes down...we just lose that particular peering point.

Things breaking once in a while is not an issue.. Things breaking once every month or few weeks is not going to be acceptable from our users.. Trying to determine if this is a 'feature' or a short term 'bug'. Cisco's and Junipers, get a premium even in the used market place, but the primary reason for it is stability... Any other that can chime in with their experiences ? Many thanks in advance.
