CCIE SP - OSPF Lab - Topology 1 - Initial + Full Configs

OSPF (Open Shortest Path First) is a foundational IGP (Interior Gateway Protocol) in Service Provider (SP) networks, offering fast convergence, hierarchical design, and efficient route distribution. Unlike simpler distance-vector protocols, OSPF’s link-state mechanism ensures each router has a complete network topology, leading to optimal path selection. In SP environments, multi-area OSPF design is crucial for scalability, reducing routing overhead and improving stability.

Additionally, OSPF supports MPLS integration, providing IP reachability for label distribution protocols like LDP and RSVP-TE.

With advanced features like LSA filtering, route summarization, and fast SPF calculations, OSPF remains a key component of high-performance carrier-grade networks.

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.
