This chapter covers the following topics:
• The processing of packets through Cisco devices using router processor (RP) switching paths or application-specific integrated circuits (ASICs)—process switching, fast switching, Cisco Express Forwarding (CEF) switching, flow-based Multilayer Switching (MLS), and CEF-based MLS.
• Basic design concepts applied to the Data Center, which include Layer 3 links, VLANs, switched virtual interfaces (SVIs), and autostate.
• Load distribution on Layer 2 and Layer 3 links with VLAN load balancing, the Gateway Load Balancing Protocol (GLBP), and equal-cost path load balancing.
• Use of internal redundancy features such as Router Processor Redundancy (RPR), ...
