Routing protocol use Timers (Intervals) to keep all routers in a domain updated. Through the use of these timers, a routing protocol is able to maintain a stable neighbor relationship and ensure routes are propagated correctly. OSPF routing devices constantly track the status of their neighbors by sending and receiving Hello Packets to confirm whether each neighbor still is functioning normally. We can use these OSPF Intervals (OSPF Timers) to adjust the network convergence time in an OSPF network. Types of OSPF Timers: OSPF uses two types of OSPF Intervals (Timers): Tells the router after how long should it Read More …

Open Shortest Path First (OSPF)
Introduction OSPF is an open source Routing protocol that handles routing for IP traffic standardized in IETF RFC2328. OSPF is classified as an Interior Gateway Protocol (IGP). This means that it distributes routing information between routers belonging to a single Autonomous System. The OSPF protocol is based on link-state or SPF technology. It was designed mainly for the TCP/IP internet environment. Main focus was to produce a protocol that responds quickly to topology changes, with small amounts of control traffic. OSPF is a dynamic routing protocol. It quickly detects topological changes in the AS (such as router interface failures) and Read More …
