STP networking and calculated topology In Figure 1-3, DeviceA, DeviceB, and DeviceC are deployed on the network, with priorities 0, 1, and 2, respectively. The path costs between DeviceA and DeviceB, DeviceA and DeviceC, and DeviceB and DeviceC are 5, 10, and 4, respectively. ...
Figure 8-50Networking diagram for a typical LAN On the network shown inFigure 8-50, the following situations may occur: Broadcast storms render the network unavailable. Loops lead to broadcast storms, which causes network breakdown. Broadcast storms InFigure 8-50, assume that STP is not enabled...

If you are running STP for a VLAN-aware bridge in the default mode (RSTP) and you have a multiple spanning tree instance (MSTI 0, also known as a common spanning tree, or CST), you can set the tree priority for a bridge. The bridge with the lowest priority is theroot...
Layer 2 LAN protocols, such as Ethernet, do not include a mechanism to recognize and eliminate endlessly looping frames. Some Layer 3 protocols implement a TTL mechanism that limits the number of times a Layer 3 networking device can retransmit a packet. Layer 2 devices do not have this mecha...
To enable proper BPDU exchange across the network, be sure to allow all VLANs participating in the PVST domain on the link between the RSTP and PVST domains. When using RSTP together with an existing PVST network, you need to define the root bridge on the PVST domain. Eith...
