Yes, 'sh ip ospf interface' will tell you the identify of both the DR and BDR on that interface.

Hi Carl,

Yes you are very right infact this command will also show you the router id of DR and BDR as well as interface ip address.

Have a look a this output

Router# show ip ospf interface ethernet 0

Ethernet 0 is up, line protocol is up

Internet Address 192.168.254.202, Mask 255.255.255.0, Area 0.0.0.0

AS 201, Router ID 192.77.99.1, Network Type BROADCAST, Cost: 10

Transmit Delay is 1 sec, State OTHER, Priority 1

Designated Router id 192.168.254.10, Interface address 192.168.254.10

Backup Designated router id 192.168.254.28, Interface addr 192.168.254.28

Also look at this link for output of some other ospf related commands

HTH, if yes please rate the post.
