Chapter 13: Understanding How the VRRP Router Failover Mechanism Prevents Network Failures
Release Description
14.2R1 In Junos OS Release 14.2R1, in some cases, during an inherit session, there is a
small time frame during which two routers are in Master-Master state. In such
cases, the VRRP groups that inherit the state do send out VRRP advertisements
every 120 seconds.

The advantage of using VRRPv3 is that VRRPv3 supports both IPv4 and IPv6 address
families, whereas VRRPv2 supports only IPv4 addresses.
The following topics describe the Junos OS support for and interoperability of VRRPv3,
as well as some differences between VRRPv3 and its precursors:

Redundancy Protocol (VRRP) (for IPv4) and Internet draft draft-ietf-vrrp-ipv6-spec-08,

VRRPv3 is not supported on routers that use releases earlier than Junos OS Release 12.2
