Yes that is correct, but the display of spanning-tree is showing the STP state blocking vs the RSTP state discarding for the link. The display showing STP states would imply the switch may be using STP vs RSTP, even though it says RSTP earlier in the display. After decades o...
STP vs. RSTP vs. MSTP STPcanfall into two meanings: In a narrow sense, STP refers to the STP protocol defined in IEEE 802.1D. In a broad sense, STP refers to the STP protocol defined in IEEE 802.1D, Rapid Spanning Tree Protocol (RSTP) defined in IEEE 802.1w, and Multiple Spanning ...

CycloneSTP is an implementation of STP (Spanning Tree Protocol) and RSTP (Rapid Spanning Tree Protocol) algorithms suitable for resource-constrained microcontrollers. STP and RSTP are network protocols that can be implemented on Ethernet bridges to ensure loop-free LAN topologies. Spanning Tree ...
另外一个问题是:Cisco为每一个VLAN维护一个STP实例,而Juniper由于RSTP为所有VLAN统一维护一个STP实例,这种情况同样会造成端口阻塞不一致,从而导致网络迁移中出现故障。 如下图所示:在某些情况下,因为运行不同的协议,导致Cisco的spanning-tree生成树计算结果与Juniper的计算结果不一致,Cisco切断了左边端口,而Juniper切断了...

Single Spanning Tree vs Multiple Spanning Trees With IEEE 802.1D STP and 802.1w RSTP standards, all of the VLANs will have one spanning-tree instance. Therefore, some will be taking suboptimal paths just like in the example topology below: Since it is a single spanning-tree instance, there ...
3C与Cisco交换机互联spanning-tree的问题 2009年03月20日星期五11:48 1、STP协议-厂商支持情况 H3C交换机支持的生成树协议类型 H3C交换机支持的生成树协议有三种类型,分别是STP(IEEE802.1D)、RSTP(IEEE 802.1W)和MSTP(IEEE802.1S),这三种类型的生成树协议均按照标 准协议的规定实现,采用标准的生成树协议报文格式...
STP Modes for a Traditional Bridge Traditional bridges operate in: PVST mode, which creates a spanning tree instance for a bridge. PVRST mode, which supports RSTP enhancements for each spanning tree instance. To use PVRST with a traditional bridge, you must create a bridge corresp...
The original STP is standardized as IEEE 802.1D. Several variations to the original STP improve performance and add capacity. Arista switches support these STP versions: Rapid Spanning Tree (RSTP) Multiple Spanning Tree (MSTP) Rapid Per-VLAN Spanning Tree (Rapid-PVST) The Overview contains the ...
