VRRP standard mode
In VRRP standard mode, only the master in the VRRP group can provide gateway service. When the master fails, the backup routers elect a new master to take over for nonstop gateway service.
Figure 30: VRRP networking
As shown in Figure 30, Router A, Router B, and Router C form a virtual router, which has its own IP address. Hosts on the subnet use the virtual router as the default gateway.
The router with the highest priority among the three routers is elected as the master, and the other two are backups.
