High Availability
IP40 (R1), the address owner, acts as the master, and IP40 (R2) acts as backup.The four end
hosts in the LAN are configured to use 192.168.1.1/24 as the default router.
The primary function of the VRRP is to send the traffic that originates from H1, H2, H3, and H4
(addressed to the Internet) to IP40 (R1), default router. VRRP specifies a mechanism that IP40
(R2) uses to start acting as the default router when IP40 (R1) fails, and the hosts in the LAN do
not become isolated. As shown in the preceding figure, the branch office network uses a single
virtual router ID (V1).
If IP40 (R1) becomes unavailable, IP40 (R2) takes over VRID (V1) and its associated virtual IP
addresses. Packets sent to the Internet using 192.168.1.1 as the router are then forwarded by
IP40 (R2). When IP40 (R1) becomes active again, it takes over as the master and IP40 (R2)
reverts to backup.
