Is spanning tree a Layer 3?
Introduction. Spanning Tree Protocol (STP) is a Layer 2 protocol that runs on bridges and switches. The specification for STP is IEEE 802.1D.
Is spanning-tree a Layer 2?
Spanning Tree Protocol (STP) is a Layer 2 link management protocol that provides path redundancy while preventing loops in the network. For a Layer 2 Ethernet network to function properly, only one active path can exist between any two stations.
What are some topological problems with a spanning tree network?
Another common topological problem with spanning tree networks involves the way that Layer 2 and 3 redundancy mechanisms sometimes interact. Suppose I have a network core consisting of two Layer 3 switches. On each segment I want these core switches to act as redundant default gateways.
What is the Spanning Tree Protocol in Layer 2?
Spanning Tree Protocol. Spanning Tree Protocol (STP) is a Layer 2 link management protocol that provides path redundancy while preventing loops in the network. For a Layer 2 Ethernet network to function properly, only one active path can exist between any two stations. Multiple active paths among end stations cause loops in the network.
Can a switch stack be the spanning tree primary root?
Do not configure an access switch as the spanning-tree primary root. You cannot have a switch stack containing a mix of Catalyst 3850 and Catalyst 3650 switches. Spanning Tree Protocol (STP) is a Layer 2 link management protocol that provides path redundancy while preventing loops in the network.
What happens to a spanning tree in catalyst?
If a network segment in the spanning tree fails and a redundant path exists, the spanning-tree algorithm recalculates the spanning-tree topology and activates the standby path. Switches send and receive spanning-tree frames, called bridge protocol data units (BPDUs), at regular intervals.
