Hello,
i have a prefix (for example x.x.x.x/24) and i have uplink from 2 provider (1. AS15412 / 2. AS3223) and as a note i do not have direct BGP session with them i bought uplink from their resellers and i have bgp session with their resellers. i announced x.x.x.x/24 to both uplink and set x3 prepend for first uplink (1. AS15412 ) and after prepend as number for this was 7 asn and for second uplink was 3 asn. so best path should be second uplink , is it right? but right now i see somewhere in world see my prefixes from second and some of them see prefix from first uplink and when i troubleshoot deeper i see AS15412 set localpref 140 and somewhere match this.
i ask my carriers and seems they do not support localpref or med . so i want know how can i force all path in world use my second uplink?
for example when i see my prefix from lg.he.net i saw it detects both path but choose first uplink as best path.
thanks,
