What is an RSTP edge port?

What is an RSTP edge port?

Edge ports. In RSTP, a designated port on the network edge is called an edge port. An edge port directly connects to a terminal and does not connect to any other routers. An edge port does not receive configuration BPDUs, and therefore does not participate in the RSTP calculation.

What port does RSTP use?

RSTP can be described by three port states: Discarding, Learning, and Forwarding….STP vs RSTP Port States.

STP RSTP Description
Disabled Discarding The port only listens for BDPUs. There is no forwarding, processing, or learning of MAC addresses.

What is difference between RSTP and MSTP?

RSTP provides rapid convergence of the spanning tree. MSTP, which uses RSTP to provide rapid convergence, enables VLANs to be grouped into a spanning-tree instance, provides for multiple forwarding paths for data traffic, and enables load balancing.

Is RSTP enabled by default Juniper?

Juniper Networks products use Rapid Spanning Tree Protocol (RSTP) on the network side of devices by default to provide quicker convergence time than the base Spanning Tree Protocol (STP) does.

What is an edge port?

Edge ports are ports of a bridge that connect to workstations or computers. Edge ports do not register any incoming BPDU activities. Edge ports assume Designated port roles. Port flapping does not cause any topology change events on Edge ports since 802.1W does not consider Edge ports in the spanning tree calculations.

What is edge port?

A port is considered as an edge port when it is directly connected to the user terminal or server, instead of any other switches or shared network segments. The edge port will not cause a loop upon network topology changes.


STP is the short form for Spanning Tree Protocol & RSTP (Rapid Spanning Tree Protocol), MSTP (Multiple Spanning Tree Protocol) are all advanced/ improved implementations of STP. In this article, we will try to understand the basic concepts of Spanning Tree Protocols and their implementation.

How do I configure MSTP?

To configure the Multiple Spanning Tree Protocol:

  1. Enable MSTP as the version of spanning-tree protocol to be configured:
  2. (Optional) Enable provider bridge participation in the MSTP instance:
  3. Configure the interfaces that participate in the MSTP instance.
  4. Configure the bridge priority:
  5. Configure hello BPDU timers.

How do I enable RSTP?

To enable RSTP globally for all Layer 2 interfaces, use the following commands.

  1. Command Line Example.
  2. Command Line Example.
  3. ftos#show spanning-tree rstp brief. ftos#show spanning-tree rstp.
