9.9(0.0) Introduced on the FN IOM.
8.3.16.1 Introduced on the MXL 10/40GbE Switch IO Module.
Usage
Information
The VRRP group only becomes active and sends VRRP packets when a link-local virtual IP address is
configured. When you delete the virtual address, the VRRP group stops sending VRRP packets.
● When VRF microcode is not loaded in CAM, the VRID for a VRRP group is the same as the VRID
number configured with the vrrp-group or vrrp-ipv6-group command.
● When VRF microcode is loaded in CAM, the VRID for a VRRP group is equal to 16 times the vrrp-
group or vrrp-ipv6-group vrid number plus the ip vrf vrf-id number. For example, if
VRF microcode is loaded and VRRP group 10 is configured in VRF 2, the VRID used for the VRRP
group is (16 x 10) + 2, or 162. This VRID value is used in the lowest byte of the virtual MAC address of
the VRRP group and is also used for VRF routing.
NOTE: Configure the same VRID on neighboring routers (Dell Networking OS or non-Dell Networking
OS) in the same VRRP group in order for all routers to interoperate.
version
Set the VRRP protocol version for the IPv4 group.
Syntax
version {2 | 3 | both}
To return to the default setting, use the no version command.
Parameters
2 Enter the keyword 2 to specify VRRP version 2 as defined by RFC 3768, Virtual
Router Redundancy Protocol.
3 Enter the keyword 3 to specify VRRP version 3 as defined by RFC 5798, Virtual
Router Redundancy Protocol.
both Enter the keyword both for in-service migration from VRRP version 2 to VRRP
version 3.

Networking OS Command Line Reference Guide.
The following is a list of the Dell Networking OS version history for this command.
Version Description
9.9(0.0) Introduced on the FN IOM.
9.7(0.0) Introduced on the S6000-ON..
9.5(0.0) Introduced on the Z9000, S6000, S4820T, S4810, and MXL.
Usage
Information
You can use the both command to migrate from VRRPv2 to VRRPv3. When you set the VRRP protocol
version to both, the switch sends only VRRPv3 advertisements but can receive either VRRPv2 or
VRRPv3 packets. To migrate an IPv4 VRRP group from VRRPv2 to VRRPv3:
1. Set the switches with the lowest priority to both.
2. Set the switch with the highest priority to version 3.
3. Set all the switches from both to version 3.
NOTE: Do not run VRRP version 2 and version 3 in the same group for an extended period of time.
