VRRP Application Example
4.2.6.4 WAN Failover
WAN failover refers to failover between Ethernet WAN interface and cellular interface. When service
transmission can’t be carried out normally due to malfunction of a certain interface or lack of bandwidth,
the rate of flow can be switched to backup interface quickly. Then the backup interface will carry out
service transmission and share network flow so as to improve reliability of communication of data
equipment.
When link state of main interface is switched from up to down, system will have the pre-set delay works
instead of switching to link of backup interface immediately. Only if the state of main interface is still
down after delay, will the system switch to link of backup interface. Otherwise, system will remain
unchanged.
