VRRP Tab
Configuration > Networking > VRRP
This tab summarizes the configuration and state for appliances deployed withVirtual Router Redundancy Protocol (VRRP).
In an out-of-path deployment, one method for redirecting traffic to the EdgeConnect appliance is to configure VRRP on a common virtual interface. Possible scenarios are:
When no spare router port is available, a single appliance uses VRRP to peer with a router (or Layer 3 switch). This is appropriate for an out-of-path deployment in which no redundancy is needed.
A pair of active, redundant appliances use VRRP to share a common, virtual IP address at their site. This deployment assigns one appliance a higher priority than the other, thereby making it theMasterappliance, and the other theBackup.

VRRP Tab Settings
| Field | Description |
|---|---|
| Admin | Options are up (enable) anddown(disable). |
| Advertisement Timer | Default is1秒. |
| Group ID | Value assigned to the two peers. Depending on the deployment, the group can consist of an appliance and a router (or L3 switch), or two appliances. The valid range is 1 to 255. |
| Interface | Interface that VRRP is using for peering. |
| 年代egment | Name of the segment, if enabled. |
| IP Address Owner | An EdgeConnect appliance cannot use one of its own IP addresses as the VRRP IP, so this will always beNo. |
| Master IP | Current VRRP Master’s Interface or local IP address. |
| Master State Transitions | Number of times the VRRP instance went from Master to Backup and vice versa. A high number of transitions indicates a problematic VRRP configuration or environment. In this case, check the configuration of all local appliances and routers, and then review the log files. |
| Preemption | Leave this selected/enabled so that after a failure, the appliance with the highest priority comes back online and again assumes primary responsibility. |
| Priority | The greater the number, the higher the priority. The appliance with the higher priority is the VRRP Master. |
| 年代tate Uptime | Time elapsed since the VRRP instance entered the state it is in. |
| 年代tate | The VRRP instance has three options: Backup– Instance is in VRRP backup state. Init– Instance is initializing, it is disabled, or the interface is down. Master– Instance is the current VRRP master. |
| Virtual IP | IP address of the VRRP instance. VRRP instances can run between two or more appliances, or an appliance and a router. |
| Virtual MAC address | MAC Address that the VRRP instance is using. On an NX Appliance, this is in 00-00-5E-00-01-{VRID} format. On virtual appliances, the VRRP instance uses the interface’s assigned MAC Address (for example, the MAC address that the hypervisor assigned towan0). |
