Greetings all,
I am new to Mikrotik and am enjoying the features of the routerboard and the OS.

We have created a core router using a PC router and the 2.8 software. We also use six RB230's with the 4 port NIC.

We have set up OSPF and it seems to run just fine until it comes to neighbor relations. The core router will only form a relationship with one of the three interfaces installed. It will route to all interfaces but it is not using the most direct path.
I have all interfaces and networks installed properly and I had the system working great until we power cycled the PC router. Now it refuses to acknowledge the other devices.
Here is a brief overview of the connections...

Router1
/ | \
/ | \
RB1 - RB2 - RB3
| | |
RB4 - RB5 - RB6

the interfaces are all 172.16.x.x subnetted /29 to accomodate wireless backhauls and we have public addresses assigned to one interface of the RB's.
There seems to be no issue with ping or traffic flow around the network other than the failure to use the best route.
Priorities have been set per the doc (unless I misread) 255 as highest 1 as lowest. Router1 seems to favor forming adjacnecy with RB3 only on power up. the cost to each link is set to 12 router 1 pri=255, rb 1-3 pri=50, rb4-6 pri = 10.

Does anyone see the what I am missing on this config?
Thank you in advance for any help!
