Aging time is the protocol packet sending interval (15 seconds by default) ×3. Shut

3.2.27 VRRP

Normally the host in one broadcasting domain will be set with a default gateway working
as the next hop of routing packet. When this default gateway can not work normally, the
host in this broadcasting domain can not communicate with the hosts in other networks
any more. To avoid this sort of single-point failure, multiple router interfaces can be set in
one broadcasting domain and implement VRRP on these routers (Virtual Router
Redundancy Protocol).
VRRP put multiple router interfaces belonging to one broadcasting domain into one
group to form a virtual router. It also allocates an IP address to the virtual router as its
interface address. This interface address can either be one router interface address or
the third party's address. This virtual address will take effect only when it is in the same
network segment as real interface address.
If router interface address is used, this router with this IP address will act as the master
router, and other routers work as the slave ones. If the third party's address is used,
