Why each option
VRRP (Virtual Router Redundancy Protocol) is a first-hop redundancy protocol that supports both IPv4 and IPv6 networks.
VRRP primarily provides active/standby redundancy and does not inherently support load balancing across multiple active routers without additional mechanisms.
HSRP and VRRP are competing protocols for first-hop redundancy and are typically not configured together on the same switch for the same VLAN due to potential conflicts.
VRRP is standardized by the IETF for both IPv4 (RFC 3768) and IPv6 (RFC 5798), providing redundant default gateway services for hosts operating with either IP version.
Standard VRRP, as defined in its core RFCs, uses plain-text authentication or no authentication, lacking native support for encrypted authentication.
