Fundamental Spanning-Tree Concepts The first important choice to make in the design of a data center network is the spanning-tree choice. It is beyond the scope of this document to describe the spanning-tree algorithms in detail. At the time of this writing, the choice is between these two algorithms: EX Series. Policy Orchestration, Network Management, Security, Quality of Service, High Availability, High Availability at Layer 2, Spanning Tree Protocol (STP), Virtual Chassis, Multichassis Link Aggregation Group (MC-LAG), High availability at Layer 3, Expanded Core and Aggregation Versus Collapsed Core and Aggregation in the Campus, Conclusion Hi all, I have installed 3 APs in a wireless Mesh network (2 x Root APs and 1 x Mesh AP) at a client site. It seems that whenever my Mesh AP fails over to another parent Root AP, spanning-Tree's loopguard kicks in on the switches trunk connected to the Mesh AP for the native VLAN and CCTV VLAN (cameras are connected to the switch) .

Spanning Tree Protocol / STP is a big topic on the CCNA exam. Many people struggle with STP so in this video, we try to break it down as much as possible. Spanning Tree follows a strict set of rules which when learnt, will allow you to answer any STP questions you get.

This video focus on the standard 802.1d (and PVST+) which is the original STP standard.

Election Process

1. Elect a Root Bridge
Switch with the lowest BID

2. Place all Root Bridge interfaces in to a Forwarding state

3. Each Non-Root switch elects a Root Port
Lowest cost
Lowest neighbour BID
Lowest neighbour port priority
Lowest neighbour port number

4. Elect a Designated Port
Lowest root cost
Lowest BID
Lowest neighbour port priority
Lowest neighbour port number

5. All other ports are placed in to a Blocking State

How Spanning Tree Protocol (STP) eliminates layer 2 loops a shared link. Ports on a point-to-point link are able to move to forwarding state quickly. 48 Port states Operational STP RSTP Enabled Blocking Discarding Enabled Listening Discarding Design considerations This document presents a list of recommendations that help to implement a safe network with regard to bridging for Cisco Catalyst switches that run Catalyst OS (CatOS) and Cisco IOS Software. This document discusses some of the common reasons that Spanning Tree Protocol (STP) can fail and the information for which to look to identify the source of the problem. When the peer-link is configured, it is set to spanning tree port type network by default. This also means that, by default, Bridge Assurance is also enabled. Do not disabled Bridge Assurance on the peer-link. You may disable Bridge Assurance on the vPC member ports. These ports won't take part in spanning tree. EoMPLS is used for point-to-point configurations, while VPLS is used in point-to-multi-point scenarios or meshed environments. If the only solution available to the customer is to obtain native IP between the data centers, there are several ways to extend a VLAN across the sites.

Introduction. Ever since the introduction of spanning-tree into the data center, network engineers have had to be cognizant of many design considerations and constraints that are typically associated with managing and maintaining a loop free topology. To overcome some of the challenges of spanning-tree Cisco introduced technologies like VSS (virtual switching system) and stackwise. Key switch configuration elements and considerations 1. Spanning tree configuration. If you chose the backup link or parallel Layer 2 design, then you've extended your Layer 2 domain from the core network into the closet. That means your closet switch is participating in the global spanning tree domain and needs to be configured appropriately. The minimum spanning tree of a planar point set can be maintained fully dynamically for any signature of size n in expected time O(log n) per update. P roof . As shown by Mulmuley, by Schwarzkopf, and by Devillers et al. [ 51 ], we can maintain the Delaunay triangulation in this time bound. spanning-tree mode For example, to enable Real Time Streaming Protocol on a switch, the administrator would run the following command: spanning-tree mode rstp. In addition to enabling STP, an administrator must select a root bridge to serve as the network's central STP reference point.

By taking advantage of the point-to-point link's characteristics, 802.1w can move a port into forwarding state much faster than before. The link type is derived from the duplex mode of the port. A link connected via a full-duplex port is considered to be point to point, whereas one that is connected via a half duplex is considered to be shared.
