The mpath diff is against 4.3 stable on given date. I was not even able to patch 4.3 release. OSPF and BGP does not came into play here yet, because to assign the same/different costs to different routes to the same destination I need to have routing table with 2 (or more) routes to the same destination. The current kernel does not allow this. Could you specify how you got this: > I have two default routes. One is IP address "A". The other is > IP address "B". (The other issues as to what gw route specific packet are not important) Thank you, Oleg --- "Vladimir B.
