A configuration BPDU is generated in one of the following scenarios: Once the ports are enabled with STP, the designated ports send configuration BPDUs at intervals specified by the Hello timer. When a root port receives configuration BPDUs, the device where the root port resides sends a copy...
A configuration BPDU is at least 35 bytes long and includes the parameters such as the BID, root path cost, and PID. A bridge processes a received configuration BPDU only if either the sender BID or PID is different from that on the local bridge receive port. If both fields are the ...
STP model is a three-step process involving the following:1- SegmentationThis is the first step of the STP marketing technique. The marketing team identifies which sub-groups or groups of consumers are within their target market.It can be done by geographic location, demographics, lifestyle, ...
It also provides multiple redundant paths for data forwarding to implement the load-balance mechanism of the VLAN data. 1.1.1 MSTP Concepts There are 4 MST regions in Figure 1-1. Each region consists of four switches, all of which run MSTP. The following introduces the concept of MSTP with...
Spanning tree builds the tree structure attempting to use the fastest links it has available for the active paths. STP uses the following steps to select its paths:1. Lowest root bridge ID (BIP)2. Lowest path cost to the root (path cost is configurable on some type of switch/bridge)3. ...
The following are some common scenarios for Layer 2 forwarding loops: STP disabled on a switch A misconfigured load balancer that transmits traffic out multiple ports with the same MAC address A misconfigured virtual switch that bridges two physical ports (Virtual switchestypically do not participate...
The following relation must be observed while configuring the timers: 2 * (Forward-time - 1) >= Max-age Related Commandsshow spanning-tree bridge - Displays spanning-tree configuration of the bridge forward time show spanning-tree detail - Displays detailed spanning-tree information show spann...

The following sequence of events demonstrate the MAC database instability issue: 1.PC1 sends a broadcast frame to S2. S2 receives the broadcast frame on F0/11. When S2 receives the broadcast frame, it updates its MAC address table to record that PC1 is available on port F0/11. ...
