Virtual router redundancy protocol
VRRP allows you to form virtual routers from groups of physical routers on your LAN. These virtual routing platforms — master and backup
pairs — provide redundancy in case of hardware failure. VRRP also allows you to easily congure a virtual router as the default gateway to
all your hosts and avoids the single point of failure of a physical router.
VRRP advantages in ease of administration and network throughput and reliability:
• Provides a virtual default routing platform
• Provides load balancing
• Supports multiple logical IP subnets on a single LAN segment
• Enables simple trac routing without the single point of failure of a static default route
• Avoids issues with dynamic routing and discovery protocols
• Takes over a failed default router:
– Within a few seconds
– With a minimum of VRRP trac
– Without any interaction from hosts
