The issue of Router 1 failing to establish an OSPF peering with Router 2, and the increase in CPU and memory usage can be attributed to a mismatch in MTU (Maximum Transmission Unit) sizes. In OSPF, for a successful adjacency to be formed, the MTU size on the interfaces that are trying to form this adjacency must match. In this case, changing the MTU to 1524 on Router 1 will make it compatible with Router 2, allowing OSPF peering to be established and customer traffic to pass through successfully.References: Implementing and Operating Cisco Service Provider Network Core Technologies (SPCOR) - Cisco

The issue of the OSPF domain receiving only the 172.17.1.0/24 route and not the default route 0.0.0.0/0 can be resolved by configuring OSPF to propagate default routes. Let’s take a look at the options:

• Option A: The configuration includes the following commands:
• router ospf 1
• default-information originate
• end

This configuration generates a default route into the OSPF domain, which is missing in this scenario.

To secure REST APIs, a network administrator should ensure that user sessions are authenticated and that the appropriate privilege level is provided for each user. This means that each API request should come with authentication credentials, and the server should validate these credentials for every request. This approach helps to maintain the stateless nature of REST APIs and ensures that only authorized users can access or modify resources. References: Best practices for securing REST APIs include using HTTPS, token-based authentication, and proper validation of input parameters to prevent common security vulnerabilities.
