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.
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.
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.

microcode is loaded.
Version 8.4.2.1 The range of valid VRID values on the E-Series when VRF microcode is loaded in
CAM changed to 1-15.
