Information
The VRRP group only becomes active and sends VRRP packets when a virtual IP address is
configured. When you delete the virtual address, the VRRP group stops sending VRRP packets.
Starting in release 8.4.1.0, you can configure a VRRP group on an interface in a non-default VRF
instance.
E-Series ExaScale only: You can configure up to 16 VRRP groups per VLAN and up to 511 groups
on all VLANs.
E-Series ExaScale and TeraScale only: Starting in release 8.4.2.1, you can configure up to 255
VRRP groups per interface if VRF microcode is not loaded, and up to 15 groups if VRF microcode is
loaded.
E-Series ExaScale and TeraScale only: Starting in release 8.4.2.1, the VRID used by the VRRP
protocol changes according to whether VRF microcode is loaded or not:
• 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.
The following example shows how the actual VRID used by a VRRP group is displayed:
• Below the command line - when VRF microcode is loaded and you enter the vrrp-group or
vrrp-ipv6-group command in VRRP-group configuration mode.
•In show vrrp command output.
Important: You must configure the same VRID on neighboring routers (Dell Force10 or
non-Dell Force10) in the same VRRP group in order for all routers to interoperate.
Example FTOS(conf)#ip vrf orange 2
FTOS(conf)#interface GigabitEthernet 3/0
FTOS(conf-if-gi-3/0)#ip vrf forwarding orange
FTOS(conf-if-gi-3/0)#ip address 1.1.1.1/24
FTOS(conf-if-gi-3/0)#vrrp-group 10
% Info: The VRID used by the VRRP group 10 in VRF 2 is 162.
FTOS(conf-if-gi-3/0-vrid-162)#virtual-ip 1.1.1.10
FTOS(conf-if-gi-3/0-vrid-162)#exit
FTOS(conf-if-gi-3/0)#no shutdown
FTOS#show vrrp
------------------
Version 8.4.2.1 When VRF microcode is loaded in CAM, the range of valid VRID values on the
E-Series changed to 1-15.
Version 8.4.1.0 Support was added for configuring a VRRP group on an interface in a non-default
VRF instance.
Version 7.6.1.0 Introduced on S-Series
Version 7.5.1.0 Introduced on C-Series
pre-Version 6.2.1.1 Introduced on E-Series
