Same as Point-to-multicast but uses Unicast instead of broadcast.
Does not have DR/BRD.
Host routes are sent to the neighbors.
Sample config for Hub-and-Spoke Topology:
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Hub:
Interface s0/0
enc frame
no frame inv
ip add 10.10.10.1 255.255.255.0
frame map ip 10.10.10.2 102
frame map ip 10.10.10.3 103
ip ospf net point-to-multipoint non-broadcast
Router ospf 1
net 10.10.10.1 0.0.0.0 area 0
neighbor 10.10.10.2
neighbor 10.10.10.3
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Spoke-1:
Interface s0/0
enc frame
no frame inv
ip add 10.10.10.2 255.255.255.0
frame map ip 10.10.10.1 201
ip ospf net point-to-multipoint non-broadcast
Router ospf 1
net 10.10.10.2 0.0.0.0 area 0
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Spoke-2:
Interface s0/0
enc frame
no frame inv
ip add 10.10.10.3 255.255.255.0
frame map ip 10.10.10.1 201
ip ospf net point-to-multipoint non-broadcast
Router ospf 1
net 10.10.10.3 0.0.0.0 area 0
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Please note that we don't have the frame-relay broadcast keyword configured.
We don't have Spoke-to-Spoke mapping but they will be able to ping each
other fr interface via L3 routing.
