Open Tutorial: OSPF Operations (0.5 days)
Synopsis
OSPF is a widely used IGP (interior gateway protocol) in both enterprise and service provider networks.
This tutorial will cover how link state protocols work in general, the different LSA types in OSPF, OSPF neighbor relationship, and OSPF best path selection. We will also discuss best practices around what routing information should be carried in OSPF.
Target audience
Technical staff who are involved in Internet technology standards, local and national network infrastructure planning & deployment, and day-to-day network operations.
Prerequisites
It is assumed that participants have a basic understanding of:
- Network operations, Internet technologies, OSI reference model and TCP/IP.
- Basic Linux command line (CLI) skills.
- The lab exercises use Cisco IOS configuration syntax.
We recommend the following Academy courses be completed before the start of the tutorial:
- Routing Fundamentals: https://academy.apnic.net/en/course/routing-fundamentals-course/
- Linux Basics virtual lab: https://academy.apnic.net/en/virtual-labs/
Other requirements
- Hardware: It is highly recommended that participants bring their own laptop computers with Wifi(b/g/n) and administrative access to system to practice the lessons learned during the workshops.
- Software: SSH Client, Telnet Client (PuTTy)
- Confirm Secure SHell (SSH) is allowed from the office or home network to access the lab infrastructure? Test ssh connectivity, try to connect to route-views.routeviews.org. For example from the CLI type: ssh [email protected]
Course outline
- Shortest Path First logic
- LSA types and LSDB
- Neighbour discovery
- Link State operation
- OSPF hierarchy/scaling
Notes
This Open Tutorial has a related lab component, covered in Open Lab: Routing/OSPF. For practical experience, participants are encouraged to join the associated Open Lab.
