Virtual Router Redundancy Protocol (VRRP)

IETF-standard FHRP (RFC 5798 for VRRPv3) with one master and backups sharing a virtual IP that may be a real interface address.

Definition

VRRP uses IP protocol 112 and multicast 224.0.0.18, with virtual MAC 0000.5e00.01XX. Default priority is 100 (255 for the address owner), advertisements every 1 second, and preemption is enabled by default. VRRPv3 supports IPv6 and centisecond timers. Junos and most vendors support VRRP.

Example

vrrp 10 address-family ipv4 / address 10.10.10.1 primary

Exam tip

In VRRP the active router is called master; in HSRP it is active.
