I have the following lab setup:
Frame Relay hub with 2 spokes.
2 PVC's each from the hub to each spoke.
Multipoint sub-interfaces configured (2 at the hub and one at each spoke).
Frame Relay map statements configured at each spoke with 'broadcast'.
ospf network type is 'broadcast'.
For DR/BDR election I have configured the hub with pri 255 and the spokes are default '1'.
On the hub when I 'sh ip ospf ne' one spoke shows up as FULL/DROTHER and the other as FULL/BDR which is correct.
However, when I goto the 'FULL/DROTHER' spoke router and 'sh ip ospf int se 0.100' it claims that it is in the STATE BDR also. I can force the spoke to be DROTHER by setting the priority to 0.
Can anyone confirm that what I am seeing is normal or abnormal. If abnormal I will post configs.
Hey there. You need to make the spokes DR-ineligible. To do this make sure both spokes have an OSPF priority of 0, and make the hub a non-zero priority (OK to leave as default 1). If possible, clear the OSPF process and you should see the following:
Hub - two OSPF neighbors as DROTHERS
Spoke - one OSPF neighbor (the hub) as DR
Hope this makes sense.
