Configuring Vrrp For Ipv4 - 3Com S7906E Configuration Manual

Reply: After receiving a request, the master sends a reply to the backup router to allocate a virtual
MAC address. Upon receiving the reply, the backup router creates a VF corresponding to the
virtual MAC address, and then the backup router becomes the owner of this VF.
Release: After a VF owner failed for a specified time, the router that takes over its responsibility will
send a release to notify the other routers in the VRRP group to delete the VF of the failed VF owner.
The format of the above four types of packets is similar to that of the advertisement in the VRRP
standard protocol mode. The difference is that a packet used in the load balancing mode is appended
with option fields, which carry information for load balancing.

Configuring the Association Between Virtual IP Address and MAC Address
After the virtual IP address of a VRRP group is associated with a MAC address, the master 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.
There are two types of association between virtual IP address and MAC address:
Virtual IP address is associated with virtual MAC address
