Task 1
Configure OSPF so that there is no hello packets exchanged on point-to-point link between R1 and R3. LSAs should not be refreshed every 30 minutes either.

R1 Configuration:
Note!
The 'ip ospf demand-circuit' is configured on one end of the connection. It is going to re-establish OSPF adjacency and negotiate the required features.
Verification:
Note!
The neighbor adjacency is built again.
