OSPF: how distance parameter is calculated ?

[Piotr]

Hi,

I have two ospf routers in the same vlan and subnet but with different 
metrics (20 vs 50). I'd like to prefer router with metric=20  but 
distance parameter is more prefered. How can i change distance parameter 
or just  ?

thanks for help
