VRRPv3

VRRPv3 (Virtual Router Redundancy Protocol version 3) provides first-hop gateway redundancy for IPv4 and IPv6 networks on NX-OS. VRRPv3 groups are configured per interface and address family on VLAN, Ethernet and port-channel interfaces as well as Ethernet/port-channel subinterfaces, and support primary and secondary virtual addresses, priority-based election, preemption with a minimum delay, millisecond advertisement timers, VRRPv2 compatibility, secondary address matching, object tracking with priority decrement and VRRS leader tags. The interface-level settings fhrp_delay_minimum and fhrp_delay_reload delay the start of the VRRPv3 state machine after an interface comes up or after a reload, and vrrs_pathways define VRRS pathways that follow the state of a VRRS leader group. VRRPv3 requires feature.vrrpv3 and is mutually exclusive with VRRP version 2 (feature.vrrp).
