This makes OSPF with message digest authentication an excellent choice for updating dynamic routing information over insecure networks. Connectionless and Connection-Oriented Communications page 43 Active Defense — A Comprehensive Guide to Network Security We can now get our information from Point A to Point B, regardless of whether the systems are located on the same logical network. ” This is where the transport layer comes in. The transport layer is where we begin to set down the rules of communication etiquette.

Again, both systems have a valid copy of the new network layout. Because we are dealing with strictly firsthand information, there are none of the pesky count-to-infinity problems that we experienced with distance vector. Our router tables are accurate, and our network is functioning with a minimal amount of updating. This allows link state to traverse a larger number of network segments. The maximum is 127 hops, but this can be fewer, depending on the implementation. Security with Link State Routing Most link state routing protocols support some level of authenticating the source of dynamic route updates.

Router B would then delete the copy of Router C’s LSP frame that it has been maintaining and forward this information along to Router A. Both routers now have a valid copy of the new network layout and realize that Network 4 is no longer reachable. If Router C is not brought down gracefully but again dies a fiery death, there would be a short delay before Router B realizes that Router C is no longer acknowledging packets sent to it. At this point Router B would realize that Router C is offline.
