Chapter Summary
A router is a multiport device that can connect
dissimilar LANs and WANs running at different
transmission speeds and using a variety of protocols
To determine the best paths across networks,
routers communicate with each other using routing
protocols
The networking industry has adopted the term
“brouter” to describe routers that take on some
characteristics of bridges
Gateways are combinations of networking hardware
and software that connect two dissimilar kinds of
networks
