Network Redundancy Pages
It is critical for industrial applications that network remains non-stop. The WR7802-XT supports STP, RSTP
and Redundant Ring technology with these web pages:
•

Network Redundancy | VRRP Page
If you are unsure as to whether to configure Redundant Gateway or VRRP (Virtual Router Redundant
Protocol) to provide a gateway failure backup mechanism, you may want to review the following information.
•
VRRP
requires all gateway participants to run VRRP protocol and it detects a gateway failure using IP
multicast.
•
Redundant Gateway
detects a gateway failure with Redundant Ring status and ICMP packets.
Since VRRP and Redundant Gateway use different protocols, you can use one or the other but not both.
