Static routing is a form of routing that occurs when a router uses a manually-configured routing entry, rather than information from a dynamic routing traffic. In many cases, static routes are manually configured by a network administrator by adding in entries into a routing table, though this ...
The “show ip route”command is one of the most important commands related to routing on Cisco IOS devices in order to show the routing table of the router. It gives you detailed information about the networks that are known to the router, either directly connected to the router, statically ...
The router will add all new routes in the routing table before updating existing routes. If the update has better information for any existing route, the router will replace the old entry with new route information. If the update has worse information for any existing route, the router will ...
If multiple routes to a destination exist, OSPF adds only the fastest route to the routing table. If two or more routes have an equal cost, it adds all of them to the routing table. It uses them to load balance. For example, R2 has two equal-cost routes for the network 30.0.0.0/8...
When the message reaches a multicast group member, the receivers (R1, R2, and R3) create an entry in its member table or update the correspondent entry if the message already exists, and then broadcast the message to their neighbors in a JOIN REPLY message, as shown in Fig. 24b. Every ...
Introduction Clos topologies have gained prominence in today's networking, primarily as a result of the paradigm shift towards a centralized data-center architecture that is poised to deliver a majority of computation and storage services in the future. Such networks are called commonly a fat tree/...
As explained earlier, the metric for the routing table entry is the OSPF-calculated cost, not a hop count (as is the case for RIP). To calculate the IP routing table entries from the SPF tree, OSPF analyzes the set SPF{} that results from calculating the SPF tree. The analysis ...

A routing table lookup algorithm is described that, for a first outbound packet, performs a first route lookup into the routing table with a first search key that includes the first packet's destination address and a first network interface identifier, and, for a second outbound packet, performs...
