Designing Routed Networks with EIGRP and OSPF

This path is intended for anyone who is interested in developing the skills needed to successfully design networks that will support voice, video, and data communications.


Expected Duration
106 minutes

Default EIGRP and OSPF settings are great for small and many medium-sized networks. However, to build large-scale networks you need to take advantage of the various features and services provided by the routing protocols. Without these features, they may not behave as you intend them. This course covers the features provided by EIGRP and OSPF that allow them to run more efficiently in large networks. Features such as route summarization, default routes, filtering, passive interface, EIGRP Stub routers, and OSPF Stubby areas, are covered.


Routing Protocol Considerations

  • start the course
  • describe interior and exterior routing protocols
  • describe route summarization
  • describe originating default routes
  • describe route redistribution
  • describe the importance of avoiding transit traffic
  • describe defensive filtering
  • describe cases for passive interfaces
  • describe routing protocol fast convergence
  • describe coexistence of IPv4 and IPv6 IGP routing
  • describe routing protocol authentication

Expanding EIGRP Design

  • describe a single-homed site
  • implement a single-homed site
  • describe a dual-homed site
  • describe geographic dispersion of HQ
  • implement summarizing towards the core
  • describe OSPF areas
  • describe OSPF LSAs
  • describe OSPF summarization
  • describe OSPF path selection
  • describe OSPF stubby areas

Practice: OSPF Path Selection

  • implement OSPF path selection
