Creating a virtual forwarder
Virtual MAC addresses enable traffic distribution across the routers in a VRRP group. To enable the
routers in the VRRP group to forward the packets, be sure to create virtual forwarders (VFs) on the routers.
Each VF associates with a virtual MAC address in the VRRP group and forwards packets sent to this
virtual MAC address.
