IP Routing: OSPF Configuration Guide, Cisco IOS Release 15M&T Americas Headquarters Cisco Systems, Inc. West Tasman Drive San Jose, CA OSPF Configuration Step by Step Guide. This tutorial is the third part of this article. OSPF adjacency process goes through the seven states; OSPF State down, OSPF State Init, OSPF State two ways, OSPF State Exstart, OSPF State Exchange, OSPF State Loading and OSPF State full. This part explains these states with DR BDR selection process in detail with examples. The Open Shortest Path First (OSPF) protocol, defined in RFC , is an Interior Gateway Protocol used to distribute routing information within a single Autonomous System. This paper examines how OSPF works and how it can be used to design and build large and complicated networks. Router(config-if)# ip ospf priority Default priority on Cisco routers is 1. A priority of 0 will prevent the router from being elected DR or BDR. Note: The DR election process is not preemptive. Thus, if a router with a higher priority is added to the network, it will not automatically supplant an existing DR. This note contains details about how the protocol forms adjacency, exchange LSAs, and everything you need to know about OSPF. Most of the notes are self compiled, but all information are pulled from "OSPF and ISIS: Choosing an IGP for Large-Scale Network by Jeff Doyle". • Share a common protocol header. • Routing protocol packets are sent with type of service (TOS) of 0. • Five types of OSPF routing protocol packets. Hello - packet type 1 Database description - packet type .Open Shortest Path First (OSPF) is an open-standard Link State routing protocol. . In Cisco IOS software, OSPF-enabled routers send Hello packets every Any Internet Protocol (IP) addresses and phone numbers used in this document are not intended to be actual addresses and phone numbers. Any examples. Then configure the console, virtual terminal lines password (both “cisco”) and Step 1: Use the router ospf command in global configuration mode to enable. The Open Shortest Path First (OSPF) protocol, defined in RFC , is an This paper examines how OSPF works and how it can be used to design and build. After creating 2-way neighbor relationship neighboring routers will start exchanging network related information. • At this stage they will decide who will send. routing information, using the Open Shortest Path First (OSPF) routing protocol. router in an OSPF area contains an identical link-state database, which is a list.
