Before you do less than full routes everywhere, first see what performance is like on the new routers.

But I'm still dealing with more immediate issues. We are taking a mix of full or partial routes from our providers. The issue seems to be when one line gets cut, it takes a bit for our old routers to recalculate the tables. Should I just take default routes? That way there is a lot less math needed when a line goes down. I'm assuming inbound BGP will still be optimized for shorted path. How will that work for the two IX's we connect to? Are they smart enough to calculate best path even if the traffic comes from outside the IX. -- Best regards, Mark mailto:m...@mailmt.com Myakka Communications www.Myakka.com ------ Thursday, April 20, 2023, 11:37:35 AM, you wrote: We did not have to do that.
