The VRRP port IP address and virtual IP address can be the same.

Hello everyone,

In most cases, at least three IP addresses are required for VRRP planning, one for each gateway port and the other for a virtual gateway.


However, if the customer requires or the address is insufficient, only two IP addresses are used.

Two gateway ports are used, and the virtual gateway uses the same IP addresse witch the gateway ports.

I was not aware if configuring like this will work. Have you tested this configuration.

The Virtual Router Redundancy Protocol (VRRP) is a computer networking protocol that provides for automatic assignment of available Internet Protocol (IP) routers to participating hosts. This increases the availability and reliability of routing paths via automatic default gateway selections on an IP subnetwork.

The protocol achieves this by creation of virtual routers, which are an abstract representation of multiple routers, i.e. master and backup routers, acting as a group. The default gateway of a participating host is assigned to the virtual router instead of a physical router. If the physical router that is routing packets on behalf of the virtual router fails, another physical router is selected to automatically replace it. The physical router that is forwarding packets at any given time is called the master router.
