BGP problem with best route

RouterOS Forwarding Protocols
1

i have set bgp local pref in one prefix , but mikrotik still use other route as best:

[amix@router001] > /ip route print detail where dst-address=185.121.84.0/24
Flags: X - disabled, A - active, D - dynamic, C - connect, S - static, r - rip, b - bgp, o - ospf, m - mme, B - blackhole, U - unreachable, P - prohibit 
 0 ADb  dst-address=185.121.84.0/24 gateway=XXX gateway-status=XXX reachable via  retn-m9 distance=20 scope=40 target-scope=10 bgp-as-path="9002,31261,199975" bgp-weight=110 bgp-local-pref=110 bgp-origin=igp

       routerboard: yes

why its chosing active route such way?

with eBGP you want to use local pref ?

follow this:

○ Local-Pref
• Mostly used in iBGP networks, higher Local-Pref is better
○ AS-Path
• Mostly used in eBGP networks, shorter as-path is better

3

I want to set up best path for route manualy, how can i do this? i cannot modify as-path with route filters

4

that is for eBGP, or other option would be prepend

5

this is incoming route, i cannot add prepend to incoming routes

6

The very first step in the BGP best path algorithm before getting into attributes is checking next hop reachability…typically when weight and local pref are higher than another route but that route isn’t selected, there is a problem with reachability of the next hop for that route.

But both gateways are reacheble and all distances are the same

8

Both peers run on the same instance?
