VRRP Session State Inheritance

This feature introduces support for VRRP session state inheritance. VRRP groups configured on the various subnets of a VLAN can inherit the state and configuration of one of the groups, which is known as the active VRRP group. When VRRP session state inheritance is enabled, only the active VRRP group, from which the other VRRP groups are inheriting the state, sends out frequent VRRP advertisements and processes incoming VRRP advertisements. The groups that are inheriting the state do not process any incoming VRRP advertisement because the state is always inherited from the active VRRP group. However, the groups that are inheriting the state do send out VRRP advertisements once every 2 to 3 minutes to facilitate MAC address learning on the switches placed between the VRRP routers.
