BGP path selection

RouterOS Forwarding Protocols
1

Hello!

I try to find out, why shorter AS path is not used.
We have CCR1016-12G, with 6.0rc11.
peer options:

     tcp-md5-key="" nexthop-choice=default multihop=no route-reflect=no hold-time=3m 
     ttl=default in-filter="" out-filter=as-elkdata-out address-families=ip,ipv6 
     default-originate=never remove-private-as=no as-override=no passive=no use-bfd=no

instance options:

      redistribute-connected=no 
      redistribute-static=no redistribute-rip=no redistribute-ospf=no 
      redistribute-other-bgp=no out-filter=as-elkdata-out client-to-client-reflection=no 
      ignore-as-path-len=no routing-table=""

Any suggestions?

You need to show the routes you have a problem with

do

/ip route print detail where dst-address in x.x.x.x/x

I censored output little bit, hopefully this is not problem. There is lots longer prefixes, they all are only announced by 3327

Does both peers use the same BGP instance?

No. I can see where it goes. So, only way to get best AS path is by using same instance? Any workarounds for this?
