CCIE SP - OSPF Lab Topology 2 - Initial + Full Configs

Open Shortest Path First (OSPF) is a widely used link-state routing protocol that plays a crucial role in Service Provider (SP) networks for dynamic and efficient IP routing. Unlike distance-vector protocols, OSPF maintains a complete topology map, enabling fast convergence and optimal path selection.

In SP environments, OSPF is typically deployed as OSPFv2 for IPv4 and OSPFv3 for IPv6, with features like multi-area design, route summarization, and traffic engineering (TE) support to improve scalability. Service providers often integrate OSPF with MPLS, using it to distribute loop-free IP reachability while relying on LDP or RSVP-TE for label switching.

Understanding OSPF's behavior in large-scale networks, including LSA types, area types (Stub, NSSA), and SPF optimizations, is essential for building resilient and high-performance SP infrastructures.

The default username and password for images used in this course is as follows, however you will hear new passwords during the course if the instructor changes the credentials: 

** For Cisco XRv you are asked for a username and password in the loading process. You can add any username and password other than admin, root, sysadmin and other reserved usernames. Go with something like Alex/cisco e.g.

Then when completely loaded, you can use cisco/cisco or admin/admin.

***For XRv9K Full image you are asked for a username and password in the loading process. You then login using the username and password that you set.
