RIPv2 Summary

The characteristics of RIPv2 follow: - Distance-vector protocol. - Use UDP port 520. - Makes Automatic summarization on network Class boundary. - Classless protocol (supports VLSMs). - Have the power to shut the Auto-summarization And make a configured manual Summarization. - Supports VLSMs. - Metric is router hop count. - Maximum hop count is 15; infinite (unreachable) routes have a metric of 16. - Periodic route updates sent every 30 seconds to multicast address 224.0.0.9. - 25 routes per RIP message (24 if authentication is used). - Invalid route marked after 180 sec. - Flush timer is 280 sec. - Hold-down timer 180 sec. - Supports authentication. - Implements split horizon with poison reverse. - Implements triggered updates. - Subnet mask included in route entry. - Administrative distance for RIPv2 is 120. - Used in small, flat networks or at the edge of larger networks. RIPv2 Convergence The steps for RIPv2 convergence are as follows: 1- When the local router sees a connected route...

EIGRP Summary

                          EIGRP Summary The characteristics of EIGRP follow: -         Hybrid routing protocol (distance vector that has link-state protocol characteristics). -         Use DUAL, first proposed by E. W. Dijkstra and C. S. Scholten, to perform distributed shortest-path routing while maintaining freedom from loops at every instant. Although many researchers have contributed to the development of DUAL, the most prominent work is that of J. J. Garcia-Luna-Aceves. -         Cisco Proprietary created in 1994. -         First released in IOS 9.21 -         Uses IP protocol 88. -         Makes Automatic summarization on network Class boundar...
