foreword
VRRP (Virtual Router Redundancy Protocol) and MSTP (Multiple Spanning Tree Protocol) are two different protocols, VRRP is a protocol used to achieve gateway redundancy, and MSTP is a protocol used to provide network redundancy and fault tolerance .
Although they are different protocols, they can be used together in a network to provide greater reliability and fault tolerance. In this case, VRRP can be used to achieve gateway redundancy, ensuring that there is always a gateway device available in the network, while MSTP can be used to provide network redundancy, ensuring that there is no single point of failure in the network.
Specifically, if a combination of VRRP and MSTP is used in the network, the two protocols can be configured on different devices. Among them, the VRRP protocol can be configured between multiple devices to provide gateway redundancy. The MSTP protocol can be configured between all devices to provide network redundancy.
In this configuration, if the gateway of one device fails, the VRRP protocol will automatically select the gateway device of another device as the active gateway and take over the traffic. At the same time, the MSTP protocol can recalculate the network topology among other devices and reconfigure the network to ensure that there is no single point of failure in the network.
The combination of VRRP and MSTP can provide higher reliability and fault tolerance, so that the network can better respond to faults and recover from faults.
