1、对于VLAN ID不等于1的情况下,其目标MAC地址为Cisco 私有的PVST+ MAC 01:00:0c:cc:cc:cd。 2、如果VLAN ID为VLAN 1,则会发送两个版本的BPDU: 3、1.一个为带上802.1Q的VLAN ID=1的BPDU包,其目标MAC地址为PVST+ MAC 01:00:0c:cc:cc:cd。 4、2.另外一个为不带VLAN标签的数据包目标MAC是01:8...
Since it is a single spanning-tree instance, there will be a single root bridge for all of the VLANs in the LAN. In this example, let’s say it’s SW1. All of the traffic will then be forwarded to SW1. Our multiple spanning-tree modes, IEEE 802.1s MSTP, PVST+, and RPVST+, ...
选项:(1)标准的IEEE 802.1d MAC (2)Cisco 私有的PVST+ MAC。
Rapid-PVST can be enabled or disabled on individual VLANs. Multiple Spanning Tree Protocol (MSTP) MST extends Rapid Spanning Tree Protocol (RSTP) to support multiple spanning tree instances on a network, but is still compatible with RSTP. By default, Arista switches use MSTP. MST supports ...
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...
The BPDUs used to exchange MSTP information are always sent untagged; the VLAN and spanning tree instance data is encoded inside the BPDU. Per-Vlan Rapid Spanning Tree (PVRST)— This feature is the IEEE 802.1w (RSTP) standard implemented per VLAN, and is also known as ...

In this intermediate training, CBT Nuggets trainer Knox Hutchinson covers the knowledge network administrators need to manage, administer and troubleshoot the spanning tree protocol on Juniper devices, ensuring an efficient and accurate link tree. Contin
剖析PVST+ 它是Cisco的私有协议,在原IEEE-802.1D标准的基础上加上特定扩展属性修改而来。它也是所有Cisco Catalyst交换机系列的默认生成树协议。相比标准的RSTP或MSTP,其优势是为每一个VLAN维护了一个独立的拓扑结构,并作单独计算。这样的话,针对冗余链路我们可以通过调整不同VLAN的生成树优先级从而实现二层帧上的负...
tree plus (rapid-PVST+) protocol based on the IEEE 802.1w standard. For information about the Multiple Spanning Tree Protocol (MSTP) and how to map multiple VLANs to the same spanning-tree instance, see Chapter 19, “Configuring MSTP.” For information about other spanning-tree features such...
