Operation Manual – VRRPH3C S5500-EI Series Ethernet Switches Chapter 1 VRRP Configuration1-11When an IP address owner exists in a standby group, if you associate the virtual IPaddress with the virtual MAC address, two MAC addresses are associated with an IPaddress. In this case, you can associate the virtual IP address of the standby group withthe real MAC address, so that the packets from a host are forwarded to the IP addressowner according the real MAC address.Follow these steps to configure the association between MAC address and virtual IPaddress:To do… Use the command… RemarksEnter system view system-view —Configure the associationbetween virtual IPaddress and MACaddressvrrp method { real-mac |virtual-mac }OptionalThe virtual MAC addressis associated with thevirtual IP address bydefault.Caution:You should configure this function before creating a standby group. Otherwise, youcannot modify the mapping between the virtual IP address and the MAC address.1.2.4 Creating Standby Group and Configuring Virtual IP AddressYou need to configure a virtual IP address for a standby group when creating thestandby group. A VRRP standby group is created automatically when you specify thefirst virtual IP address for the standby group. If you specify a virtual IP address for thestandby group later, the virtual IP address is only added to the virtual IP address list ofthe VRRP standby group.I. Configuration prerequisitesBefore creating standby group and configuring virtual IP address, you should firstconfigure the IP address of the interface and ensure that the virtual IP address to beconfigured is in the same network segment as the IP address of the interface.II. Configuration procedureFollow these steps to create standby group and configure virtual IP address:
