I have 4 routers in my lab. FR1 is the frame relay switch (2621), R1(2621), R2(2651) & R3(2651) are all connected in a mesh using sub interfaces - R1 has pvc to R2&R3 and so on. Without OSPF I can ping all points successfully. With OSPF I can also ping all the loopbacks built onto the routers. OSPF seems to work but when I do:
#show ip ospf neighbor
the neighbours show as FULL but with 0 priority - and checking the detail each router has 0.0.0.0 as their DR.
I'm about to try changing the priorities, but given the fact I did a write erase before building the lab this evening, what could cause the priorities to move from the default of 1 to 0?
Thanks in advance.
