Abstract
In one embodiment, a system includes a TRILL-enabled network that includes a first physical routing bridge (RB) and a second physical RB, logic adapted for creating a virtual RB logically connected to the first and second physical RBs to form a vLAG group at an edge of the network, logic adapted for determining a first distribution tree linking the first physical RB to every other RB in the network in a non-repeating fashion, ending with the second physical RB, and logic adapted for determining a second distribution tree linking the second physical RB to every other RB in the network in a non-repeating fashion, ending with the first physical RB, wherein when a multicast packet is received by the virtual RB from one of the physical RBs, the multicast packet is distributed according to either the first or the second distribution tree thereby preventing looping.
