Ospf DR & BDR 1

[kpari05]

hello,
here's a sample output of the command "show ip ospf neibhbor detail" :

Neighbor 10.139.24.254, interface address 10.135.16.1
In the area 0.0.10.1 via interface Serial0/0.1
Neighbor priority is 0, State is FULL, 6 state changes
DR is 0.0.0.0 BDR is 0.0.0.0
Options is 0x52
LLS Options is 0x1 (LR)
Dead timer due in 00:00:33
Neighbor is up for 9w6d
Index 1/1, retransmission queue length 0, number of retransmission 6
First 0x0(0)/0x0(0) Next 0x0(0)/0x0(0)
Last retransmission scan length is 1, maximum is 1
Last retransmission scan time is 0 msec, maximum is 0 msec
-
Looking at the above output.....does it mean that this network being a point-to-point frame relay connection has no DR/BDR election ? [because they're both showing 0.0.0.0] ?

thanks

Correct. OSPF will always form an adjacency with the neighbor on the other side of a point-to-point interface such as point-to-point serial lines. There is no concept of DR or BDR in this situation.

thanks for the confirmation
