OSPF Network Types - Point to point
OSPF Network Types - Point-to-point
1. Broadcast (Broadcast multi-access network) - Default for Ethernet interfaces.
2. Non-broadcast (Non-Broadcast Multi-Access (NBMA) network) - Exampple is a frame relay network which does not support multicast and broadcast.
3. Point-to-point - Can be configured regardless of the underlying technology (even on Ethernet interfaces).
4. Point-to-multipoint - Useful with frame relay networks that support “pseudo-broadcast”.
5. Point-to-multipoint Non-broadcast - Can be used in frame relay networks where pseudo-broadcast is not supported.
CONFIGURE:
R1:
conf t
interface Serial0/0
ip address 10.10.12.1 255.255.255.0
!
router ospf 1
network 10.10.12.0 0.0.0.255 area 0
end

R2:
conf t
interface Serial0/0
ip address 10.10.12.2 255.255.255.0
!
router ospf 1
network 10.10.12.0 0.0.0.255 area 0

VERIFY:
show ip ospf neighbor
show interfaces s0/0 !To check layer 2 encapsulation.
show ip ospf interface !To check the network type.
