The Building Scalable Cisco Internetworks (BSCI 642-901)
is a qualifying exam for the Cisco Certified Network Professional CCNP,
Cisco Certified Design Professional CCDP, and Cisco Certified Internetwork
Professional CCIP certifications. The BSCI 642-901 exam will certify that
the successful candidate has important knowledge and skills necessary to use
advanced IP addressing and routing in implementing scalability for Cisco ISR
routers connected to LANs and WANs. The exam covers topics on Advanced IP
Addressing, Routing Principles, Multicast Routing, IPv6, Manipulating
Routing Updates, Configuring basic BGP, Configuring EIGRP, OSPF, and IS-IS.
The following information provides general guidelines for the content
likely to be included on the exam. However, other related topics may also
appear on any specific delivery of the exam. In order to better reflect the
contents of the exam and for clarity purposes the guidelines below may
change at any time without notice.
Exam Topics:
