Mikrotik OSPF ABR understanding

Tue Jan 22, 2013 8:14 am

I have MT connected to backbone, but when i look in ABR status i can see next:
>routing ospf area-border-router print detail 
 0 instance=IRKI routerid=20.0.64.0 state=intra-area gateway=172.20.64.110 
   interface=vlan_68_inet cost=10 area=IRKI


Why routerid=20.0.64.0 with non backbone area are ABR?
20.0.64.0 is simply CISCO router who redistribute only connected networks
2 name="IRKI" instance=IRKI type=default area-id=20.0.64.0
Why backbone neighbours in ASBR table?
