The document discusses default routes in computer networking, detailing how packets are routed when no specific route exists. It also explains Enhanced Interior Gateway Routing Protocol (EIGRP), a Cisco-proprietary protocol allowing efficient router communication, and compares it to its predecessor, IGRP. Lastly, it covers Open Shortest Path First (OSPF), a link state routing protocol used within a single autonomous system.
How Different Cisco Routing Protocal Work
- 9. 1.In computer networking, the default route is a setting on a computer defining the packet forwarding rule to use when no specific route can be determined for a given Internet Protocol (IP) destination address. All packets for destinations not established in the routing table are sent via the default route.
- 11. 1.EIGRP (Enhanced Interior Gateway Routing Protocol) is a network protocol that lets routers exchange information more efficiently than with earlier network protocols. EIGRP is a Cisco-proprietary routing protocol for TCP/IP. It's actually based on Cisco's proprietary IGRP routing protocol, with many enhancements built into it. Because it has its roots in IGRP, the configuration is similar to IGRP; however, it has many link state characteristics that were added to it to allow EIGRP to scale to enterprise network sizes. To know these characteristics read our previous article.
- 12. 1.Open Shortest Path First (OSPF) is a routing protocol for Internet Protocol (IP) networks. It uses a link state routing algorithm and falls into the group of interior routing protocols, operating within a single autonomous system (AS).
