You need to implement a First Hop Redundancy Protocol (FHRP) in a dual stack (IPv4 and IPV6) environment that utilizes devices from multiple different vendors. Which protocol best meets these needs?

HSRP (Hot Standby Router Protocol) is a Cisco proprietary FHRP, which limits its use in multi-vendor environments.

GLBP (Gateway Load Balancing Protocol) is a Cisco proprietary FHRP and only supports IPv4, making it unsuitable for dual-stack environments.

VRRPv1 is an open standard but only supports IPv4, which does not meet the requirement for a dual-stack (IPv4 and IPv6) environment.

VRRPv2 is an open standard protocol, allowing interoperability across different vendors in a multi-vendor environment. While VRRPv2 natively supports IPv4, the VRRP protocol family (which includes VRRPv3) fully supports IPv6, making VRRP the best choice among the given options for a dual-stack, multi-vendor FHRP.
