   Dear Alexey,   
      
   08 Jan 22 09:29, you wrote to me:

   What do you mean by "properly configured"? You mean the out-of-the-box   
   configuration still does not allow this?   
      
   A Cisco router would not allow the same L2 network on two different L3   
   interfaces IMHO, even if one of the prefixes is more specific. If it would,   
   how should it know whether the destination is behind a gateway or can be   
   reached by ARP/NDP?
