Abstract
Embodiments of the invention relate to controllable virtual link aggregation Internet Protocol (IP) forwarding. One embodiment includes forming a first virtual link aggregation (vLAG) between a first pair of switches for a first system that implements virtual router redundancy protocol (VRRP). A second vLAG is formed between a second pair of switches for a second system that implements VRRP. A VRRP role is forwarded by each switch of the first pair of switches and the second pair of switches to one another. The VRRP role is synchronized between each of the first pair of switches and the second pair of switches. VRRP packets are forwarded to particular switch ports of the first pair of switches and the second pair of switches.
