When an OSPF interface is enabled, it identifies itself as being an =
interface of a certain network type: Broadcast if it is connected to a =
fast ethernet or ethernet, point-to-point if it is E-1, but, "sh ip ospf =
interface" shows:
FastEthernet11/1 is up, line protocol is up
  Internet Address X.X.29.129/30, Area 0
  Process ID 8888, Router ID X.X.0.133, Network Type POINT_TO_POINT, =
Cost: 1
  Transmit Delay is 1 sec, State POINT_TO_POINT,
  Timer intervals configured, Hello 10, Dead 40, Wait 40, Retransmit 5
    Hello due in 00:00:09
  Index 5/5, flood queue length 0
  Next 0x0(0)/0x0(0)
  Last flood scan length is 1, maximum is 40
  Last flood scan time is 0 msec, maximum is 4 msec
  Neighbor Count is 1, Adjacent neighbor count is 1
    Adjacent with neighbor X.X.0.134
  Suppress hello for 0 neighbor(s)

Why it shows the network type "POINT-TO-POINT" instead of =
"BROADCAST"??What changes the network type?I'll appreciate any idea.
