FortiGate-7000E VRRP HA

FortiGate-7000E supports the Virtual Router Redundancy Protocol (VRRP), allowing you to configure VRRP HA between FortiGate-7000E data interfaces. You can also add a FortiGate-7000E data interface to a VRRP domain with other VRRP routers.

To set up a FortiGate-7000E VRRP to provide HA for internet connectivity:

1. Add a virtual VRRP router to the internal interface to the FortiGate-7000E(s) and routers to be in the VRRP domain.
2. Set the VRRP IP address of the domain to the internal network default gateway IP address.
3. Give one of the VRRP domain members the highest priority so it becomes the primary (or master) router and give the others lower priorities so they become backup routers.

During normal operation, the primary VRRP router sends outgoing VRRP routing advertisements. Both the primary and backup VRRP routers listen for incoming VRRP advertisements from other routers in the VRRP domain. If the primary router fails, the new primary router takes over the role of the default gateway for the internal network and starts sending and receiving VRRP advertisements.

On the GUI you can go to Network > Interfaces and right click on the column header and add VRRP to the Selected Columns list to see the VRRP status of the data interfaces that are operating as VRRP routers.

You can use the following command to find information about VRRP state synchronization:

diagnose test application vrrpd {1 | 2 | 3 | 4 | 5}

1 resynchronize all FPMs from the primary FPM.

2 send a synchronize request from the current FPM.

3 show statistics.

4 clear all statistics.

5 clear packet age.
