Building Scalable Cisco Internetworks

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.

Implement EIGRP operations.

• Explain the functions and operations of EIGRP (e.g., DUAL).
• Configure EIGRP routing. (e.g., Stub Routing, authentication, etc.)
• Verify or troubleshoot EIGRP routing configurations.

Implement multiarea OSPF operations.

• Explain the functions and operations of multiarea OSPF.
• Configure multiarea OSPF routing. (e.g., Stub, NSSA, authentication, etc.)
• Verify or troubleshoot multiarea OSPF routing configurations.

Describe integrated IS-IS.

• Describe the features and benefits of integrated IS-IS.
• Configure and verify integrated IS-IS.

Implement Cisco IOS routing features.

• Describe, configure or verify route redistribution between IP routing IGPs. (e.g., route-maps, default routes, etc.)
• Describe, configure or verify route filtering (i.e., distribute-lists and passive interfaces).
• Describe and configure DHCP services (e.g., Server, Client, IP helper address, etc.).

Implement BGP for enterprise ISP connectivity

• Describe the functions and operations of BGP.
• Configure or verify BGP operation in a non-transit AS (e.g., authentication).
