If you have a large network, it would make sense to do this is a phased approach where you select a handful of sites, configure them for OSPF and have them redistriute into EIGRP and then progressively remove EIGRP routing from the network.

Protocol (EIGRP) Routing Information protocol (RIP) and Open Shortest Path First (OSPF)have been considered as the pre-eminent routing protocols for real-time applications In this paper, we have analyzed and simulated a proposed
Routing Protocols (such as BGP, OSPF, RIP, EIGRP, etc…) are designed to help routers advertise adjacent networks and since the internet is a network of networks, BGP helps to propagate these networks to all BGP Routers across the world.
Routing protocols such as RIP and EIGRP are Distance Vector routing protocols. These are called Distance Vector protocols because they base routing decisions on the “distance” of the remote destination in terms of the number of network layer hops that the packet will have to traverse. OSPF and IS-IS are Link State routing protocols. They are called Link State protocols because they base

OSPF [5] [7] [9] is a routing protocol which was defined as version 2 in RFC 2328; used to allow routers to dynamically learn routes from other routes and to advertise routes to other
The purpose of routing protocols is to learn of available routes that exist on the enterprise network, build routing tables and make routing decisions. Some of the most common routing protocols include RIP, IGRP, EIGRP, OSPF, IS-IS and BGP. There are two primary routing protocol types although many different routing protocols defined with those two types. Link state and distance vector
The behaviour of routing protocols EIGRP, OSPF, BGP is studied. The performance of each routing protocol is different from each other. Each of them has different architecture, adaptability, routing algorithms, processing delays and convergence capabilities. Among different routing protocols, EIGRP and OSPF have been considered as the pre-eminent routing protocols for the real -time application
To redistribute all OSPF routes into EIGRP: RouterB(config)# router eigrp 15 routes, a default metric of 20 will be applied to routes of all routing protocols except for BGP. Redistributed BGP routes will have a default metric of 1 applied by OSPF. By default, OSPF will only redistribute classful routes into the OSPF domain. To configure OSPF to accept subnetted networks during
interior gateway routing protocols EIGRP and OSPF, section 3 compares the two routing protocols against a number of criteria to identify strengths and weaknesses and section 4 proposes a number of considerations for implementing these protocols based upon the identified strengths and weaknesses of each. Section 5 concludes the paper and proposes future work which could be performed. II
Just do BGP to receive 0/0, advertise a public prefix (with filters), redistribute into OSPF at the edge router (or L3 switch). I don’t trust firewall code to do “fancy routing” well, so I draw the line at informing them — no redistribution, area boundaries, etc. on the firewalls.

Border Gateway Protocol (BGP) BGP is a standardized exterior gateway protocol (EGP), as opposed to RIP, OSPF, and EIGRP which are interior gateway protocols (IGP’s). BGP Version 4 (BGPv4) is the current standard deployment. BGP is considered a “Path Vector” routing protocol. BGP was not built to route within an Autonomous System (AS), but rather to route between AS’s. BGP maintains a

In order for a floating static route to kick in, first the primary route would need to be withdrawn from the routing table which means that the EIGRP or OSPF algorithm have detected the change and have completed their recomputation of the new set of shortest paths. You see, in this case, the floating static route would not be faster than the routing protocol itself.
The next part of the book details specific information on deploying each interior gateway protocol (IGP)—including EIGRP, OSPF, and IS-IS—in real-world network environments. Part III covers advanced topics in network design, including border gateway protocol (BGP), high-availability, routing protocol security, and virtual private networks (VPN). Appendixes cover the fundamentals of each

6/03/2018 · Hi Ashfaq, This may not be a simple task if you have a very large network. If you have a large network, it would make sense to do this is a phased approach where you select a handful of sites, configure them for OSPF and have them redistriute into EIGRP and then progressively remove EIGRP routing from the network.

Border Gateway Protocol (BGP) BGP is a standardized exterior gateway protocol (EGP), as opposed to RIP, OSPF, and EIGRP which are interior gateway protocols (IGP’s). BGP Version 4 (BGPv4) is the current standard deployment. BGP is considered a “Path Vector” routing protocol. BGP was not built to route within an Autonomous System (AS), but rather to route between AS’s. BGP maintains a

In order for a floating static route to kick in, first the primary route would need to be withdrawn from the routing table which means that the EIGRP or OSPF algorithm have detected the change and have completed their recomputation of the new set of shortest paths. You see, in this case, the floating static route would not be faster than the routing protocol itself.
