I am now officially studying for the CCNP Service Provider Track, is a really cool certification with a lot of stuff about OSPF, IS-IS, BGP, and IOS XR. Because IOS XR is something new for me, the best way to digest it, is just setting up a small lab and play with it. I will be using the IOS XR image CSR1000v, running on VMWare workstation. I will not speak about how to set it up, because there are a ton of places on the internet speaking about it, just google it
The blueprint of the OSPF V2 in the exam 642-883 SPROUTE is:
1.1 Describe multi-area OSPFv2 operations
1.2 Implement multi-area OSPFv2 IOS-XR
1.3 Implement different OSPF areas (stubby, totally stubby, NSSA) on IOS-XR
1.4 Implement OSPF neighbor authentication on IOS-XR
1.5 Troubleshoot OSPF IOS-XR configuration errors
