Configuration Task List
Complete these tasks to configure VRRP for IPv4:
Enabling Users to Ping
Virtual IP Addresses
You can configure whether the master switch responds to the received ICMP echo
requests, that is, whether the virtual IP address of a standby group can be
successfully pinged.
Follow these steps to enable a user to successfully ping the virtual IP addresses of
standby groups:
c
CAUTION: Configure this function before creating a standby group. Otherwise,
your configuration will fail.
Configuring the
Association Between
Virtual IP Address and
MAC Address
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
When an IP address owner exists in a standby group, if you associate the virtual IP
address with the virtual MAC address, two MAC addresses are associated with an
