What are living root bridges locally known as?

What are living root bridges locally known as?

Long before the availability of modern construction materials, the Khasi devised an ingenious way to traverse the turbulent waterways and link isolated villages: living root bridges, locally known as jing kieng jri.

Which state is famous for root bridge?

Meghalaya

What is the purpose of a root bridge?

The root bridge serves as a reference point for all spanning-tree calculations to determine which redundant paths to block. An election process determines which switch becomes the root bridge.

How do you calculate the root bridge?

The root bridge is selected by manually configuring its bridge priority to a low value. 32768 is the default value out of a range from 0 to 61440. If all switches in a single spanning tree have the same bridge priority, the switch with the lowest MAC address will become the root bridge.

Which switch is the current root bridge?

SW-1

What is bridge priority?

The bridge priority determines which bridge is elected as the root bridge. If two bridges have the same path cost to the root bridge, the bridge priority determines which bridge becomes the designated bridge for a LAN segment.

Which switch is the root?

The switch with the highest switch priority (the lowest numerical priority value) is elected as the root switch. If all of the switches are configured with the default priority (32768) for a VLAN with ID 1 (that is, a bridge priority of 32769), then the switch with the lowest MAC address becomes the root switch.

What two items make up a bridge ID?

• Explanation: The three components that are combined to form a bridge ID are bridge priority, extended system ID, and MAC address.
• Explanation: Switches learn MAC addresses at the learning and forwarding port states.
• Explanation: Only one switch can be the root bridge for a VLAN.

Which three components are combined to form a bridge ID?

Explanation: The three components that are combined to form a bridge ID are bridge priority, extended system ID, and MAC address.

What are two network design features?

Which two network design features require Spanning Tree Protocol (STP) to ensure correct network operation? (Choose two.)

• static default routes.
• implementing VLANs to contain broadcasts.
• redundant links between Layer 2 switches.
• link-state dynamic routing that provides redundant routes.

What is the value used to determine which port on a non root bridge?

Explanation: STP establishes one root port on each non-root bridge. The root port is the lowest-cost path from the non-root bridge to the root bridge, indicating the direction of the best path to the root bridge. This is primarily based on the path cost to the root bridge.

How is STP cost calculated?

SW3 receives BPDUs on its 10 Mbit interface (cost 100) and on its 1000 Mbit interface (cost 4). It will use its 1000 Mbit interface as its root port (shortest path to the root bridge is 19+19+4=42). SW3 will forward BPDUs to SW4. The root path cost field will be 100….Spanning-Tree Cost Calculation.

Bandwidth	Cost
100 Mbit	19
1000 Mbit	4

What is the property of STP root port?

Root Port selection is based on the port having lowest cost to the Root Bridge (CAT1). For PVST (Per VLAN Spanning Tree) path cost will depend on bandwidth of links and cost value is as shown below for most commonly used links. Also it is important to understand how path cost calculate.
