Routing Problem

RouterOS General
1

Please, help me.
I have MK router with 6 peers. One of them connect me to netwok 200.x.x.0/23 directly (trought a cisco router into my AS). The problem is that the MK router show me that:

DST-ADDRESS PREFSRC G GATEWAY DISTANCE INTERFACE

1319 Db 200.x.x.0/23 r CISCO_MY_AS 200 red_acceso
1320 ADb 200.x.x.0/23 r IP_PROVIDER 30 provider


where

CISCO_MY_AS is a router into my network, in the same datacenter. This router run iBGP against the MK router.
IP_PROVIDER is the peer of one of my providers connected directly to MK.
The point is, I need to route this network (200.x.x.0/23) trought CISCO_MY_AS peer.

Do you undetstand my problem ?

Thanks a lot.

This is good for your education: http://wiki.mikrotik.com/wiki/BGP_Best_Path_Selection_Algorithm

And this is a solution to your problem: http://wiki.mikrotik.com/wiki/BGP_Case_Studies_1 (search for “routing filters”)

Good luck,
