Breaking a stack switches (with SVIs as gateway) - using HSRP

As an IT administrator, understanding how to break a stack of switches with an SVI (Switched Virtual Interface) as a gateway is critical. This process can be slightly complicated, but with the proper guidance, it can be done quickly and easily.

When breaking a stack of switches with an SVI as a gateway, it’s important to understand the basics of stack switching and the different types of stack architectures. A stack of switches typically consists of multiple switches that are connected together in a logical and physical manner. The switches in the stack work together to provide high availability, redundancy, and improved performance. Each switch in the stack has its own IP address and is managed as one unit.

The most common type of stack architecture is the distributed switch stack. This type of stack consists of multiple switches that are connected together using either a dedicated stack cable or a trunk port. Each switch in the stack can be managed individually, and the stack can be broken down into smaller stacks for easier management.

When creating an SVI as a gateway in a stack of switches, the SVI is created on the switch that will act as the gateway. All of the other switches in the stack will then route traffic to the SVI. To ensure that the SVI is correctly configured, the SVI should be configured with an IP address, a default route, and the correct switch or trunk port.

Once the SVI is configured correctly, the next step is to configure the HSRP (Hot Standby Router Protocol). This protocol is used to provide redundancy to the gateway by allowing multiple routers or switches to share the same IP address. The HSRP will assign a virtual IP address to each router or switch in the stack. The virtual IP address is used as the gateway address and is shared by all of the switches in the stack.

When breaking a stack of switches with an SVI as a gateway, it is important to ensure that the HSRP is configured correctly. Each router or switch should be configured with the same virtual IP address. The HSRP should also be configured with the same priority and authentication information. The HSRP should also be configured to use the SVI as the primary gateway.

Once the HSRP is configured correctly, the stack of switches can be broken down. To do this, each switch in the stack should be removed from the stack cable or trunk port. Once the switch has been removed, the switch can be connected to the SVI as the gateway. When the switch is connected to the SVI, the switch will begin to route traffic through the SVI as the gateway.

Breaking a stack of switches with an SVI as a gateway is not a difficult task, but it is important to understand the basics of stack switching and the different types of stack architectures. By understanding the basics of stack switching and configuring the HSRP correctly, an IT administrator can easily break a stack of switches with an SVI as a gateway.
