priority (Protocols VRRP)
Statement introduced before Junos OS Release 7.4.
Statement introduced in Junos OS 11.3 for the QFX Series.
Statement introduced in Junos OS Release 14.1x53-D20 for the OCX Series.
Statement introduced in Junos OS Release 18.1R1 for the SRX Series devices.
Configure a Virtual Router Redundancy Protocol (VRRP) device’s priority for becoming the master default device. The device with the highest priority within the group becomes the master. VRRP is designed to eliminate the single point of failure inherent in the static default routed environment. VRRP specifies an election protocol that dynamically assigns responsibility for a virtual router to one of the VRRP routers on a LAN. The VRRP router controlling the IP address(es) associated with a virtual router is called the Master, and forwards packets sent to these IP addresses. The election process provides dynamic fail-over in the forwarding responsibility when the Master become unavailable. Any of the virtual router's IP addresses on a LAN can then be used as the default first hop router by end-hosts. The advantage gained from using VRRP is a higher availability default path without requiring configuration of dynamic routing or router discovery protocols on every end-host.
Range: 0 through 255
Default: 100. If two or more devices have the highest priority in the VRRP group, the device with the VRRP interface that has the highest IP address becomes the master, and the others serve as backups.
