Group load balancing for virtual router redundancy

摘要

Load balancing in a network section implementing VRRPv3 may be supported in a way that is easier to implement than that described in § 4.2 of RFC 5798. This may be done by (a) receiving, by a virtual router redundancy protocol (VRRP) router on a local area network (LAN), a group load balancing identifier (GLB ID) value; (b) sending, by the VRRP router, the GLB ID value to at least one peer VRRP router on the LAN, the VRRP router and the at least one peer VRRP router on the LAN defining a group of peer VRRP routers; and (c) responsive to receiving, by the VRRP router, a GLB ID value from a peer VRRP router on the LAN, (1) selecting a master for the group of peer VRRP routers, and (2) responsive to the VRRP router selecting itself as the master for the group of VRRP routers, (A) adjusting, by the VRRP router, a priority value of the VRRP router for the group of VRRP routers, and (B) sending, by the VRRP router, a notification to the at least one VRRP peer device, that the VRRP router is the master for the group of VRRP routers.
