Usage Information
The VRRP group only becomes active and sends VRRP packets when a link-local virtual IP address is congured.
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
congured 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 congured 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: Congure 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 dened by RFC 3768, Virtual Router
Redundancy Protocol.
3 Enter the keyword 3 to specify VRRP version 3 as dened by RFC 5798, Virtual Router
Redundancy Protocol.
both Enter the keyword both for in-service migration from VRRP version 2 to VRRP version 3.
Defaults 2
Command Modes VRRP
Supported Modes Full–Switch
Command History
This guide is platform-specic. For command information about other platforms, see the relevant Dell 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.
