Explanation
VRRP (Virtual Router Redundancy Protocol) is a first-hop redundancy protocol that supports both IPv4 and IPv6 networks.
Common mistakes.
- A. VRRP primarily provides active/standby redundancy and does not inherently support load balancing across multiple active routers without additional mechanisms.
- B. 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.
- D. Standard VRRP, as defined in its core RFCs, uses plain-text authentication or no authentication, lacking native support for encrypted authentication.
