Example Supported Releases OS10# show route-map map1 pbr-statistics 10.3.0E or later Virtual Router Redundancy Protocol VRRP allows you to form virtual routers from groups of physical routers on your local area network (LAN). 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. NOTE: When an IPv6 VRRP group and OSPFv3 are configured on the same interface, OSPFv3 does not converge on that interface. For OSPFv3 convergence to happen on that interface, configure a static IPv6 neighbor entry on the VLAN interface with the peer link-local IPv6 address and MAC address. To configure a static IPv6 neighbor entry with the peer link-local IPv6 address and MAC address, use the ipv6 neighbor command. Configuration notes All Dell EMC PowerSwitches except MX-Series, S4200-Series, S5200 Series, and Z9332F-ON: Priority 255 is not supported. 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.
