OSPF with Multiple Paths - Point-Point

enterboy1984

scenario - 5 routers full mesh - all share the same cost "bandwidth" running OSPF. 

is it normal to see a traceroute from 3 to 7  as per below doing loadbalancing?

3     6

   5

4     7

I dont think this is right so i'm adding a lower cost to prefer for routers from each corner to flow thru 5 and. The network layout is point to point.. 
Is the traceroute above normal for OSPF loadbalancing. To me doesnt seem right.. .but wanted to check as havent been able to find the right answer out there.

Hi

The loadbalance is ok but it depends of the location of the destination. Could you please share a diagram to see where the destination is located? I prefer partial mesh on the topologies.

I'm attempting to replicate an ISP prior to exchange BGP advertisements between customers and ASNs.

internal peering in ISP 1 is the one im referring to. all BGP neighbors are w/ loopback IPs.
