The WR7802-XT provides the VRRP (Virtual Router Redundant Protocol) feature, which allows the host to
continuously direct traffic to the default gateway without changing the default gateway configuration.
In a VRRP domain, the VRRP device should have the same Virtual Router ID, Virtual IP and Advertisement
Interval time and choose one of the VRRP devices as the VRRP Master. The other becomes the VRRP Backup
that takes over the VRRP Master immediately.
VRRP
Virtual Router ID
This is a virtual ID range from 1~255. The device within the same VRRP domain
should have the same Virtual Router ID.
Virtual IP
This is the virtual IP of the VRRP domain. This is the Gateway IP of the clients.
Priority
VRRP priority is 0 to 255. The greater the number, the higher the priority. In a
VRRP domain, the VRRP device should have the same Virtual Router ID and
Virtual IP and choose who should be the VRRP Master. The device with the
highest priority is selected as the VRRP Master. The priority setting can be
manually changed and the range is 1 to 254. Priority 0 is reserved for special
uses and priority 255 for the Virtual owner.
Adv. Interval
This field indicates how often the VRRP devices exchange the VRRP settings.
The time unit is seconds and the default setting is 1 second. In a VRRP domain,
the VRRP devices should have the same Adv. Interval as well.
