Virtual active gateway

A virtual active gateway is created by configuring the same IPv4 address in both the interface-VLAN context and the active-gateway context.

Virtual active gateway enables the user to configure the same IPv4 address as both the interface VLAN (SVIs) address as well as the active gateway address. A virtual active gateway is useful when the primary purpose of the SVI is to provide just a first hop gateway service to its clients and does not need a separate set of IPv4 addresses on each device and a virtual IPv4 address to serve the gateway functionality.
