I use bgp confederation. The problem with BGP med is that the priority of as path len is higher than BGP med, which means some upstream with longer as path would never be selected. Even though it has the best ping. Douglas Fischer <fischerdouglas@gmail.com> 于 2023年10月10日周二 上午2:59写道：
It makes a lot sense! On a scenario of an Off-Path RR, aigp works perfectly.
But... You are probably using this to ebgp, right? Why not set med as aigp, and then test med?

Hi all,
I plan to use bgp_aigp instead of bgp_med to find the optimal route based on incremental pings per node. For example, if the delay between one node and another node is 40, then bgp_aigp increases by 40 after passing this ibgp.
void bgp_aigp [O] This attribute contains accumulated IGP metric, which is a total distance to the destination through multiple autonomous systems. Currently, the attribute is not accessible from filters.
But it seems I can't modify this value?
