Usage
Information
The VRRP group only becomes active and sends VRRP packets when you configure a link-local virtual IP
address. When you delete the virtual address, the VRRP group stops sending VRRP packets.
When you do not load the VRF microcode in the CAM, the VRID for a VRRP group is the same as the
VRID number configured with the vrrp-group or vrrp-ipv6-group commands.
When you load the VRF microcode in the CAM, the VRID for a VRRP group equals 16 times the vrrp-
group or vrrp-ipv6-group vrid number, plus the ip vrf vrf-id number. For example, if
you load the VRF microcode and you configure the VRRP group as 10 in VRF 2, the VRID 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: For all routers to interoperate, configure the same VRID on neighboring routers (Dell EMC
Networking or non- Networking) in the same VRRP group.
