Priscilla;
Couldn't it be argued that the *act* of routing is actually a layer 3
activity, however the routing protocols actually reside at the application
layer. My reasoning for this, is if you look at the various routing
protocols, their function is to exchange information, and it is a different
process that actually forwards the packets. For example, you can configure
a cisco router with static routes to build its routing table *or* you can
configure OSPF, RIP, EIGRP, etc. Which results in new process running on
the router to manage the information exchange, yet the actual routing of the
packets are still managed by the same process that static routes uses. I am
not necessarily disagreeing with you, just trying to start some conversation
on the subject.
Thanks

Network layer. Routing is a fundamental component of the network layer.
