How is OSPF different from RIP?

The main difference between OSPF and RIP is that RIP only keeps track of the closest router for each destination address, while OSPF keeps track of a complete topological database of all connections in the local network.

Why a network running OSPF converges its routing tables faster than a network running RIP when a link goes down?

The most important is that OSPF converges much faster than RIP due to its calculation algorithm. This might not be significant in a small size network but in large enterprise networks, this will be a time out.

Which of the following is the most significant core difference between routing protocols OSPF and RIP?

The principal difference is that RIP falls in the category of distance vector routing protocol whereas OSPF is the example of link state routing. Another difference is that RIP uses bellman ford algorithm while OSPF uses Dijkstra algorithm. RIP and EIGRP are the examples of the Distance vector routing protocols.

What is the advantage of OSPF protocol?

The main advantage of a link state routing protocol like OSPF is that the complete knowledge of topology allows routers to calculate routes that satisfy particular criteria. This can be useful for traffic engineering purposes, where routes can be constrained to meet particular quality of service requirements.

What is difference between RIP v1 and v2?

RIP v1 is an older, no longer much used routing protocol. RIP v2 is a classless protocol and it supports classful, variable-length subnet masking (VLSM), CIDR, and route summarization. RIPv2 supports authentication of RIPv2 update messages (MD5 or plain-text).

Can you use RIP and OSPF together?

The operation of the RIP and OSPF routing protocols is interface dependent. Each interface and virtual sub-interface can have RIP and OSPF settings configured separately, and each interface can run both RIP and OSPF routers.

How does the speed of convergence affect the network?

Convergence time A larger network will converge more slowly than a smaller one. In case of a new route being advertised, triggered updates can speed up RIP’s convergence but to flush a route that previously existed takes longer due to the holddown timers in use. OSPF is an example of a fast-converging routing protocol.

Which algorithm is used by OSPF to compute the shortest path?

OSPF was designed as an interior gateway protocol (IGP), for use in an autonomous system such as a local area network (LAN). It implements Dijkstra’s algorithm, also known as the shortest path first (SPF) algorithm.

What is the highest priority among the following routing protocols?

Table 2-1 lists the default external priorities. When different routing protocols are configured with the same priority, the system selects the optimal route based on the internal priority….Route Priority.

Why OSPF is preferred over BGP?

Scale: BGP is more flexible and scalable than OSPF and it is also used on a larger network. Preferred path: OSPF is used to determine the fastest route while BGP puts emphasis on determining the best path. Protocol: In OSPF, internet protocol is used. While in BGP, transmission control protocol is used.

Why OSPF is better than RIP?

OSPF routing protocol has complete knowledge of network topology, allowing routers to calculate routes based on incoming requests. OSPF protocol has no limitations in hop count, unlike RIP protocol that has only 15 hops at most. So OSPF converges faster than RIP and has better load balancing.

What is the difference between Rip and OSPF protocol?

OSPF protocol has no limitations in hop count, unlike RIP protocol that has only 15 hops at most. So OSPF converges faster than RIP and has better load balancing. OSPF multicasts link-state updates and sends the updates only when there is a change in the network.

What are the networks in OSPF?

In OSPF, the networks are classified as areas, sub-areas, autonomous systems, and backbone areas.

What is osfospf protocol?

OSPF protocol best fits for complex networks that comprise multiple subnets working to ease network administration and optimize traffic. It effectively calculates the shortest path with minimum network traffic when the change occurs.

What is OpenOSPF routing protocol?

OSPF routing protocol collects link state information from routers in the network and determines the routing table information to forward packets. This occurs by creating a topology map for the network.
