An example of how to configure the backup system for VRRP with a synchronization group.

1. Add the synchronization group configuration to the existing configuration for the 99 VRRP group on dp0p1p1.

   user@system# set interfaces dataplane dp0p1p1 vrrp vrrp-group 101 sync-group ALPHA
   user@system# set interfaces dataplane dp0p1p1 vrrp vrrp-group 101 sync-group ALPHA version 3

2. Display the VRRP configuration on dp0p1p1.

   user@system# show interfaces dataplane dp0p1p1 vrrp

   vrrp {
        vrrp-group 101 {
            interface {
            }
            priority 20
            sync-group ALPHA
            version 3
            virtual-address 172.16.0.24
        }
    }

3. Create the VRRP configuration node for dp0p1p2 on R2. This configuration enables VRRP on that interface. Assign the VRRP group.

   user@system# set interfaces dataplane dp0p1p2 vrrp vrrp-group 101
   user@system# set interfaces dataplane dp0p1p2 vrrp vrrp-group 101 version 3

4. Specify the virtual address of the VRRP group.

   user@system# set interfaces dataplane dp0p1p2 vrrp vrrp-group 101 virtual-address 172.16.30.24

5. Enable RFC 3768-compliant MAC address handling and create the VRRP interface.

   user@system# set interfaces dataplane dp0p1p2 vrrp vrrp-group 101 rfc-compatibility

6. Set the priority of this system to 20.

   user@system# set interfaces dataplane dp0p1p2 vrrp vrrp-group 101 priority 20

7. Add the VRRP group on dp0p1p2 to the synchronization group.

   user@system# set interfaces dataplane dp0p1p2 vrrp vrrp-group 101 sync-group ALPHA

8. Commit the configuration.

   user@system# commit

9. Optional: Display the configuration.

   user@system# show interfaces dataplane dp0p1p2 vrrp

   vrrp {
        vrrp-group 101 {
            priority 20
            rfc-compatibility
            sync-group ALPHA
            version 3
            virtual-address 172.16.30.24
        }
    }
