642-901 BSCI
Building Scalable Cisco Internetworks

Exam Description

The Building Scalable Cisco Internetworks (BSCI 642-901) is a qualifying exam for the Cisco Certified Network Professional CCNP®, Cisco Certified Internetwork Professional CCIP®, and Cisco Certified Design Professional CCDP® 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

Implement RIP operations

• Explain the functions and operations of EIGRP (eg.. rip versions)
• Configure RIP routing ( eg.. Offset-list , passive interface, distribute-list)
• Verify or troubleshoot RIP routing configurations.

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).
• Configure BGP path selection. (i.e., Local Preference, AS Path, Weight or MED attributes).

Implement multicast forwarding

• Describe IP Multicast (e.g., Layer-3 to Layer-2 mapping, IGMP, etc.).
• Describe, configure, or verify IP multicast routing (i.e., PIM Sparse-Dense Mode).

Implement IPv6

• Describe IPv6 addressing operations.
• Describe IPv6 interoperation with IPv4.
• Describe, configure or verify OSPF routing with IPv6 addressing.
