These virtual routing platforms -master and backup pairs-provide redundancy during hardware failure. VRRP also allows you to easily configure a virtual router as the default gateway to all your hosts. It also avoids the single point of failure of a physical router. VRRP: • Provides a virtual default routing platform • Provides load balancing • Supports multiple logical IP subnets on a single LAN segment • Enables simple traffic 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 traffic ○ Without any interaction from hosts NOTE: The default behavior of VRRP is active-active. If you do not want the VRRP backup gateway to forward traffic on behalf of the active VRRP gateway in a non-VLT setup, use the no vrrp mode active-active command disable the VRRP active-active feature. Configuration VRRP specifies a master, or active, router that owns the next-hop IP and MAC address for end stations on a LAN. The master router is chosen from the virtual routers by an election process and forwards packets sent to the next-hop IP address. If the master router fails, VRRP begins the election process to choose a new master router which continues routing traffic. VRRP packets transmit with the virtual router MAC address as the source MAC address. The virtual router MAC address associated with a virtual router is in 00:00:5E:00:01:{VRID} format for IPv4 and 00:00:5E:00:02:{VRID} format for IPv6. The VRID is the virtual router identifier that allows up to 255 IPv4 and IPv6 VRRP routers on a network. The first four octets are unquenchable, the last two octets are 01:{VRID} for IPv4 and 02:{VRID} for IPv6. The final octet changes depending on the VRRP virtual router identifier. 734 Layer 3
