requests, that is, whether the virtual IP address of a standby group can be successfully

Follow these steps to enable a user to successfully ping the virtual IP addresses of

standby groups:

Enter system view

Enable users to ping

virtual IP address of the

standby group

Configure this function before creating a standby group. Otherwise, your configuration

After the virtual IP address of a standup group is associated with a MAC address, the

master switch takes the configured MAC address as the source MAC address of the

packets to be sent, so that the hosts in the internal network can learn the association

between the IP address and the MAC address and thus forward the packets to be

forwarded to the other network segments to the master switch properly.

There are two types of association between virtual IP address and MAC address:

Virtual IP address is associated with virtual router MAC address

By default, a MAC address is created for a standby group after the standby group is

created, and the virtual IP address is associated with the virtual MAC address. With

such association adopted, the hosts in the internal network need not update the

association between IP address and MAC address when the master switch changes.

Virtual IP address is associated with real MAC address of the interface
