Q:

What is the difference between the types of routes allowed by default into IS-IS and OSPF areas?

Answer

By default, all routes are advertised into all OSPF areas. This includes interarea OSPF routes and external routes that have been injected into OSPF. By default, IS-IS does not advertise interarea or external routes into an area, but injects a default route.

Q:

Why are multiple protocols used, such as a package, addressing, delivery, and transportation, instead of using one protocol defining everything?

Answer

Using multiple protocols is modular and allows changes to one protocol without affecting the others. For example, if the addressing protocol is dependent on the delivery protocol, changes to one would imply changes need to be made to the other.
