Make the proper selection for your network.10. Use the arrow keys to highlight the RIP receive info option.11. Use the ENTER key to toggle the entry. RIP1 is the default, and the other choices are RIP2,RIP1/RIP2, and DON’T RCV.12. Use the arrow keys to highlight the RIP2 auth type option.13. Use the ENTER key to toggle the entry. NONE is the default, and the other choices arePASSWORD and MD5.14. If PASSWORD or MD5 is chosen, the next selection is the user defined choice of the passwordin the RIP2 auth string field. Use the arrow keys the highlight the RIP2 auth string field.15. The password, up to 16 characters in length, may be entered here.16. The +PORT- command can be used to go to the next available port, when there is a portconfigured. Use the SPACE bar to advance to the next port for configuration. Repeat the entireprocedure as above in order to configure the new selected port.IP OSPF ConfigurationOSPF (Open Shortest Path First) is a Link-State Protocol. OSPF distributes routing informationbetween routers belonging to a single Autonomous System (AS). In an Autonomous System,routers exchange routing information through a common routing protocol.An Autonomous System may contain one or more networks, but each network within the AS mayor may not support subnetting. Every OSPF routing domain must have a “Backbone”. An OSPFbackbone distributes routing information between areas in an OSPF routing domain. Thebackbone of an OSPF routing domain is an OSPF area possessing an area ID of 0.0.0.0. BecauseOSPF protocol only broadcasts link state updates when topology has changed, it is considered“quiet” when compared to RIP protocol, which has to periodically send a portion, or all of itsrouting table to its neighbors.Convergence (the time it takes to recalculate routing tables) under OSPF protocol is instantaneousand not periodic because of the use of IP Multicast to send the link-state updates. Updates are onlysent when routing changes occur instead of periodically, ensuring better use of availablebandwidth.OSPF employs “flooding” to exchange link-states with other routers. Any change in routinginformation is flooded to all routers in the network. The use of “areas” puts a boundary on theexplosion of link-state updates. All routers within an area will have the exact link-state database.
