Re: Dynamic cost?

Hello Mike,

There is no concept of latency by peer in any main stream routing protocol because latency can be influenced by traffic load, which would create a real mess trying to understand the traffic flow. If you know one link is always lower latency than the next you simply set the cost manually at startup.

The Babel routing protocol does actually have such a concept; it's not currently implemented in Bird, however. See https://tools.ietf.org/html/draft-jonglez-babel-rtt-extension-01 for details. -Toke
