As you can see, an internetwork based around a true link
state protocol such as OSPF is considerably more complex to design
and operate than one based on a distance vector protocol. As with
all things in life, there are tradeoffs. With a distance vector
routing protocol, the internetwork can be designed, deployed, and
troubleshot fairly easily; within larger networks, however, problems
occur with the size of routing table updates and speed of
convergence. With link state routing, an internetwork is more
complex to design and troubleshoot, and uses more router processor
time, but it does converge quickly. |
