Routers
- While a switch can keep track of MAC addresses to which it connects, but a fault all of those devices connected to a switch, they belong to the same IPv4 or IPv6 network. The device used to interconnect those networks is a router. And when we first configure a router and tell it what networks it's connected to, that router adds those directly connected networks to its IP routing table. And in networks with more than one router, those routers can exchange routing information using a routing protocol such as OSPF. But to make things easy to visualize, consider this topology with a single router. In this example, the router is directly connected to three networks. Interface Gig 2 is directly connected to the 10.1.1.0 network, and that network has 24 bits in it's subnet mask. Interface Gig 3 is directly connected to the 192.168.1.0 network, and that network also has 24 bits in its subnet mask. But what about that 0.0.0.0…
