Command History Version 8.3.19.0 Version 8.4.2.1 Version 8.4.1.0 Version 8.3.7.0 Version 8.3.2.0 Introduced on S4820T The range of valid VRID values on the E-Series when VRF microcode is loaded in CAM changed to 1-15. Introduced on E-Series ExaScale, C-Series, and S-Series. Introduced on S4810 Introduced on E-Series TeraScale 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. 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.
