Answer:
Routing table and routing table population.
Explanation:
A router is an intermediate network device used to determine a good path for routing packets. It is a layer 3 device. Each interface of the router is a broadcast domain, that is, it represents a network.
It uses its routing table to find paths to a network. The router's routing table can populated (to add more routes) statically and dynamically.
To populate a routing table statically, use the format, "IP rout 'network address' 'subnet mask' 'next hop address'".
To populate dynamically, the protocols like RIP, OSPF, BGP, EIGRP etc, are used. The static routing is good for small networks because routing table population is manual while dynamic routing is good for large networks because it's routing table population is automatic.
