Virtual Router Redundancy Protocol (VRRP) | 1143
Note: On E-Series routers, 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:
Figure 58-19. VRID used when VRF microcode is not loaded
• When VRF microcode is loaded in CAM, the VRID for a VRRP group is equal to 16 times the
vrrp-group vrid 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 that the actual VRID used by a VRRP group is displayed below the command line when you enter
the
vrrp-group or vrrp-ipv6-group command in VRRP-group configuration mode, and in show vrrp
command output:

Important: You must configure the same VRID on neighboring routers (Dell Force10 or non-Force10) in
the same VRRP group in order for all routers to interoperate.
FTOS(conf)#interface GigabitEthernet 3/0e

FTOS(conf-if-gi-3/0)#vrrp-group 111

The VRID used for the VRRP group
is the same as the VRID configured
with the vrrp-group command.

% Info: The VRID used by the VRRP group 10 in VRF 2 will be 162.

The VRID used for the VRRP group
is different from the VRID configured
with the vrrp-group command when
VRF microcode is loaded.
