Support high availability within a Layer 2 domain, switches are normally interconnected using redundant links, while computing nodes have dual-homed connection to the switches. This session will cover the spanning tree protocol (STP) that builds a loop-free logical topology when you have redundant paths in the network. It also covers port channels and virtual port-channels (vPCs) that bind several interfaces to provide fault-tolerance and high-speed links between switches, routers, and computing nodes.

Key Topics:

• Rapid PVST+ Overview – 0:44
• Security STP Edge Port with BPDU Guard – 19:28
• Disabling STP with BPDU Filter – 24:16
• Protecting STP Topology with Root Guard – 27:11
• Problem with Unidirectional Links – 31:13
• Protecting Against Loops – 36:10
• Port Channels – 38:39
• Port Channels and LACP – 46:39
• Port-Channel Load Balancing – 50:01
• Virtual Port Channels – 52:09
• vPC Building Blocks – 58:29
• vPC at Multiple Layers – 1:10:14
• vPC Peer-Gateway – 1:12:24
• vPC Peer-Switch – 1:15:53
