CCNP Service Provider (350-501 SPCOR) study materials
The CCNP Service Provider v1.0 Learning Matrix for the 350-501 SPCOR training references a lot of Cisco Live presentations.
Unfortunatly almost all links are broken at the time of writing this post. I've been able to find all except one of the presentations from all over the internet from a mix of AD infested presentation sharing sites.
