The definitive resource for the NRS II exams—three complete courses in a book

Alcatel-Lucent is a world leader in designing and developing scalable systems for service providers. If you are a network designer or operator who uses Alcatel-Lucent's 7750 family of service routers, prepare for certification as an A-L network routing specialist with this complete self-study course. You'll get thorough preparation for the NRS II exams while you learn to build state-of-the-art, scalable IP/MPLS-based service networks.

The book provides you with an in-depth understanding of the protocols and technologies involved in building an IP/MPLS network while teaching you how to avoid pitfalls and employ the most successful techniques available. Topics covered include interior routing protocols, multiprotocol label switching (MPLS), Layer2/Layer3 services and IPv6. The included CD features practice exam questions, sample lab exercises, and more.

• Prepares network professionals for Alcatel-Lucent Service Routing Certification (SRC) exams 4A0-101, 4A0-103, 4A0-104 and NRSII4A0
• Covers content from Alcatel-Lucent's SRC courses on Interior Routing Protocols, Multiprotocol Label Switching, and Services Architecture
• Specific topics include MPLS (RSVP-TE and LDP), services architecture, Layer2/Layer 3 services (VPWS/VPLS/VPRN/IES/service inter-working/IPv6 tunneling), and OSPF and IS-IS for traffic engineering and IPv6.
• CD includes practice exam questions, lab exercises and solutions.

This Self-Study Guide is the authoritative resource for network professionals preparing for the Alcatel-Lucent NRS II certification exams.
