Training Program on OSPF Routing in Dhaka


Date: February, 2014
Open Shortest Path First (OSPF)

OSPF is an adaptive routing protocol for Internet Protocol (IP) networks. It uses a link state routing algorithm and falls into the group of interior routing protocols, operating within a single autonomous system (AS). OSPF is the most widely-used interior gateway protocol (IGP) in large ISP networks.

The Internet Protocol is the technological backbone of modern communication structures that includes simple file transfers, complexly distributed applications as well as integrated telephony. Sound knowledge of the underlying protocol mechanisms constitutes the basis for the successful use of the network infrastructure. The workshop IP Routing / OSPF gives an in-depth overview regarding the IP Protocol Suite, the different approaches in IP Routing as well as the function and configuration of OSPF. We believe, through training the participant understand the followings:
OSPF Router Types
• Internal Router
• Backbone Router
• Area Border Router (ABR)

The benefits of OSPF
Routing packets through an internetwork is a complex task. In a multi-protocol enterprise network with hundreds of possible routes, static routes will not suffice. In order to keep an accurate, up-to-date routing table in an enterprise network, you need a robust, efficient, scalable link state routing protocol. Open Shortest Path First protocol (OSPF) meets all of these requirements. The Internet Engineering Task Force (IETF) designed OSPF to be a scalable, efficient, and quickly converging routing protocol. Because the IETF designed OSPF, it is an open standard routing protocol and can run on routers from a variety of vendors, including Cisco, Lucent, and Nortel. As a result, if you oversee a large enterprise network supported by products from multiple vendors, you can use a single routing protocol. This approach will help ease the pains of network administration and troubleshooting.
