HSRP (Hot Standby Routing Protocol)

Hi Ramon,

You can only use configure HSRP / VRRP / GLBP on “routed” (L3) interfaces, not on switchports (L2 interfaces).

You have two options:

  1. Configure the standby commands on the VLAN interface, all switchports that are in the same VLAN will be able to reach the virtual IP address.

or

  1. Make a switchport a “routed” interface by using “no switchport” and configure the standby commands on this interface. In this case only devices that are connected to this interface will be able to reach the virtual IP address.

The reason you get the overlapping error is because you already configured the 192.168.1.0/24 subnet on the VLAN interface, you can’t configure the same subnet on multiple interfaces.

Does this help?
