Is EIGRP better than OSPF?

Scalability of the OSPF is higher than EIGRP because EIGRP is complicated and vendor-specific and incapable of migrating from one vendor to the other. Conversely, OSPF is an open standard and simple protocol through which the network can be scaled easily.

Does EIGRP converge faster than OSPF?

The network convergence time is faster than OSPF networks, because EIGRP network can learn the topology information and updates more rapidly. As a result, data packets in EIGRP network reach faster to the destination compared to OSPF network. The packet loss in the EIGRP network is less than in OSPF network.

How does EIGRP show feasible successor?

Finally, the command show ip eigrp topology all-links can be used to show the entire topology table including successor, feasible successor, and non-successor routes.

What is difference between OSPF and Ibgp?

The main difference between OSPF and BGP is that OSPF is an intra-domain routing protocol using link state routing, and the routing operation is performed inside an autonomous system while BGP is the inter-domain routing protocol that uses path vector routing, with the routing operations performed between two …

Which is the fastest routing protocol?

EIGRP
EIGRP is still the fastest protocol among all three. OSPF has a slightly longer initialization time compare to RIP and both OSPF and RIP has much longer initialization time than EIGRP.

Why do we use EIGRP?

EIGRP is a simple protocol to understand and deploy. It’s IPv6-ready, scales effectively in a well-designed network, and provides extremely quick convergence times. Other EIGRP advantages include: Easy transition to IPv6 with multi-address family support for both IPv4 and IPv6 networks.

Why OSPF is faster than RIP?

OSPF allows a router to build a shortest path tree with a router as the root. Because the link-state information provides richer information than does this in vector, OSPF typically converges faster than RIP when there is a failure in the network.

What does a router do if it has no EIGRP feasible successor?

When there are no feasible successors, a route goes into Active state and a route recomputation occurs. A route recomputation commences with a router sending a query packet to all neighbors. While in Active state, a router cannot change the next- hop neighbor it is using to forward packets.

What are three features of EIGRP?

The characteristics of EIGRP follow:

• Hybrid routing protocol (distance vector that has link-state protocol characteristics).
• Uses IP protocol 88.
• Classless protocol (supports VLSMs).
• Default composite metric uses bandwidth and delay.
• You can factor load and reliability into the metric.

Is OSPF still used?

OSPF is the most widely used but it is not the only choice. With that said, it is the most standardized IGP and that allows for optimal vendor interoperability. OSPF is primarily used for internal routing because it’s a link-state routing protocol.

Is OSPF TCP or UDP?

OSPF Packets Because OSPF does not use UDP or TCP, the OSPF protocol is fairly elaborate and must reproduce many of the features of a transport protocol to move OSPF messages between routers. There can be one of five OSPF packet types inside the IP packet, all of which share a common OSPF header.

Which layer is OSPF?

Application Layer
OSPF and BGP belong to the Application Layer.

What are successor and feasible successor in EIGRP?

Two terms that you will often encounter in the EIGRP world are the successor and feasible successor. Here are the definitions of these two terms: successor – the route with the best metric to reach a particular network. This route will be placed in the routing table.

What’s the difference between EIGRP and OSPF multicast addresses?

EIGRP Multicast address is 224.0.0.10 & OSPF Multicast addresses are 224.0.0.5 & 224.0.0.6. EIGRP uses a feasible successor as a backup path for the destination networks. So, the Convergence time is very less as compared with OSPF. Now, let’s recap all the differences between EIGRP and OSPF. Convergence Time is very less.

Why does EIGRP have faster convergence time than OSPF?

The EIGRP does not send full periodic routing updates, that is the reason it has fast convergence time. While, EIGRP is not aware of entire network connections, so it relies on its neighbour’s advertisement.

What is the difference between a successor and a feasible successor?

successor – the route with the best metric to reach a particular network. This route will be placed in the routing table. feasible successor – alternative routes to a particular network that can be used immediately if the currently best route (the successor) fails, without causing a routing loop. These routes are stored in the EIGRP topology table.
