Otherwise, your configurationwill fail.1.2.3 Configuring the Association Between Virtual IP Address and MACAddressAfter the virtual IP address of a standup group is associated with a MAC address, themaster switch takes the configured MAC address as the source MAC address of thepackets to be sent, so that the hosts in the internal network can learn the associationbetween the IP address and the MAC address and thus forward the packets to beforwarded to the other network segments to the master switch properly.There are two types of association between virtual IP address and MAC address:z Virtual IP address is associated with virtual router MAC addressBy default, a MAC address is created for a standby group after the standby group iscreated, and the virtual IP address is associated with the virtual MAC address. Withsuch association adopted, the hosts in the internal network need not update theassociation between IP address and MAC address when the master switch changes.
