RFC defines a new configuration option that allows the router to accept any packet sent to a VRRP address, regardless of whether the VRRP Primary is the address owner. The Pingable VRRP Interface feature, when enabled, allows the VRRP primary to respond to both fragmented and unfragmented ICMP echo requests packets destined to a VRRP address (or addresses). A virtual router in backup state discards these. For any packet destined to a VRRP address (or addresses), the VRRP primary responds with VRRP address as the source IPv4 address and VRMAC as the source MAC address. A configuration option controls whether the router responds to Echo Requests sent to a VRRP IP address. Dell EMC Networking firmware includes a separate configuration option that controls whether the router responds to ICMP Echo Requests. When Echo Replies are disabled using that option, the VRRP primary does not respond to Echo Requests, even if this new option is enabled. VRRP Route/Interface Tracking The VRRP Route/Interface Tracking feature extends the capability of the Virtual Router Redundancy Protocol (VRRP) to allow tracking of specific route/interface IP states, within the router, that can alter the priority level of a virtual router for a VRRP group. Exception to this is, if that VRRP group is the IP address owner, and, in that case, its priority is fixed at 255 and cannot be reduced through the tracking process. VRRP Route/Interface Tracking provides a way to ensure the best VRRP router is primary for the group by altering VRRP priorities to the status of tracked objects, such as IP interface or IP route states. In the process of altering the VRRP priorities the priority must not go below 1 or above the configured priority. NOTE: Note that the primary-only switches on a priority change if preempt is enabled.
