Prior to working on the expression for the OSPF
models, some considerations may be done regarding the network type.
From Figure (12), it is obvious that RIP performs better than OSPF
at the beginning (first convergence), but whenever a link failure happens, longer transmission time or more complicated topology, OSPF
offers a stability and reliability in the transmission that RIP cannot offer, where it can be seen from figure (13) the throughput with RIP plunged, and that because the limited number of hops, and the number of updates RIP usually takes and repeats (by default every 30 seconds), which will occupy the time and the path, leading to more dropped packets and decreasing in the throughput.

Extensive deployment of intradomain routing protocols such as OSPF
has drawn an ever increasing attention to Internet TE in recent years.
The second attack allows the flooding of what are known as Disguised LSAs, whereby a victim router would accept spoofed LSAs which it believed were generated by another router within the OSPF
With A* algorithm all routers in one topology area should share all of the network information, like in OSPF
or IS-IS that use SPF algorithm.
The utility maintains multiple links between its locations, but occasionally, due to OSPF
link-metric misconfigurations, traffic would choose a slower, less-efficient path over an available faster one.
Any advanced computer library collection specializing in programmer guides for network designers will want OSPF
and IS-IS: Choosing an IGP for Large-Scale Networks: it covers large-scale systems operating in the real world and is organized to help network engineers and architects compare OSPF
Verizon supports four routing protocols for its IP VPN service - Border Gateway Protocol (BGP), static routing, Enhanced Interior Gateway Routing Protocol (EIGRP) and Open Shortest Path First (OSPF
Additional key features: enforced enterprise-class routing, offering robust routing capabilities, including support for Routing Information Protocol (RIP) v1/2, Open Shortest Path First (OSPF
), and Border Gateway Protocol (BGP) v4; rate limiting per port; 802.1w rapid spanning tree; per VLAN spanning tree (PVST); and secure shell (SSH).
