Description

Configure the interval, in milliseconds, between Virtual Router Redundancy Protocol (VRRP) advertisement packets.

All routers in the VRRP group must use the same advertisement interval.

Options

milliseconds—Interval between advertisement packets.

  • Range:

    • 10 through 40,950 milliseconds for VRRPv3.
    • 100-999 milliseconds for VRRP.
    Note:

    When configuring VRRPv2, we recommend using advertise-interval instead of fast-interval.

  • Note:

    When configuring VRRP for IPv4, if you have chosen not to enable VRRPv3, you cannot set a value less than 100 for fast-interval. Commit check fails if a value less than 100 is configured.

  • Default: 1 second

Required Privilege Level

interface—To view this statement in the configuration.

interface-control—To add this statement to the configuration.

Release Information

Statement introduced before Junos OS Release 7.4.
