The Service Provider Routing and
Switching track enables you to demonstrate a thorough understanding of networking
technology in general and Juniper Networks service provider routing and switching
platforms. JNCIP-SP, the professional-level certification in this track, is designed
for networking professionals with advanced knowledge of routing and switching
implementations in Junos. The written exam verifies your basic understanding of
advanced routing technologies and related platform configuration and troubleshooting
skills.
This track contains four certifications:
- JNCIA-Junos: Junos, Associate. For details, see JNCIA-Junos.
- JNCIS-SP: Service Provider Routing and Switching, Specialist. For details, see JNCIS-SP.
- JNCIP-SP: Service Provider Routing and Switching, Professional. For details, see
the sections below.
- JNCIE-SP: Service Provider Routing and Switching, Expert. For details, see JNCIE-SP.
Exam Preparation
We recommend the following resources to help you prepare for your exam. However, these resources
