Abstract: Various embodiments of the invention allow for rapid communication in virtual link trunking (VLT) networks in which network traffic flows over not all-homed VLT peer devices, while honoring Equal Cost Multi Path (ECMP) decisions and normal route decisions about next hops.

In embodiments, instead of a VLAN interface-IP addresses a routing MAC address is used when forming the sub-LAG.
