multiple wan issue

Thu Sep 11, 2014 4:16 pm

hey guys,

here is the scenario

mikrotik with 5 interface.
the first 3 are connected with isp1 and has bgp on all 3, with separate peering ip
interface 4 is connected to isp2 with a /30 peering ip and not running any bgp or any routing protocol.
interface 5 connects to a switch and distributed.

the client wants to take a service from isp and distribute it among his clients.

lets say
isp1 59.152.91.130, 59.152.90.130 and 59.152.89.130 are the three peering ip
59.152.91.130 for internet
59.152.90.130 for caching
59.152.89.130 for internet-exchange(ix)

isp2 203.189.231.2 and the server that provides the service is 203.189.231.6

now, whenever his clients want to reach 203.189.231.6, they get routed through isp1 instead of isp2 even though the distance in isp2 is closer.
in routes, dst-add 0.0.0.0/0 is added with all 4 gateways and internet traffic goes through all of them except when they want to reach 203.189.231.6; thats when they go through isp1

what info do you need to help me?

client runs 5.26 on x86

But now the client complains that bandwidth drops randomly on his other connection. Considering he is doing bgp on his other connection and there is no static route on the other interface, I can't figure out where the problem is
