Pfiou, back in front of my home computer since too long !

Let's play with BGP and make some policy-based routing :akko_fistup: :akko_fistup: :akko_fistup:

I wanted to avoid to have to do this, because I'm not sure of the logic to have here. But it seems I can't avoid playing with PBR (https://en.wikipedia.org/wiki/Policy-based_routing), not because of URPF (https://en.wikipedia.org/wiki/Reverse-path_forwarding#Unicast_RPF), I've found a workaround this, but because of the OVH internal ping monitoring, which is brokken with my routing policy, and I'm starting to be tired of this routing issues.

I also hope to fix my high ping issue, I've some nodes with a ping higher of what they should have. That's probably an internal routing issue, it should be better with appropriate policies.

Also making PBR with "ip rule" will fix the issue to get all the ebgp routes grabbed by bird displayed when making an "ip route show", I'll not need anymore to add a " | grep -v bird" :neocat_laugh_sweat:
