| 发明名称 | Virtual link aggregation extension (vLAG+) enabled in a trill-based fabric network | ||
| 摘要 | In one embodiment, a method for providing virtual link aggregation (vLAG) in a transparent interconnection of lots of links (TRILL)-enabled network, includes creating a virtual routing bridge logically connected to a first physical routing bridge and a second physical routing bridge to form a vLAG group at an edge of the TRILL-enabled network; determining a first distribution tree linking the first physical routing bridge to every other routing bridge in the TRILL-enabled network in a non-repeating fashion, ending with the second physical routing bridge; determining a second distribution tree linking the second physical routing bridge to every other routing bridge in the TRILL-enabled network in a non-repeating fashion, ending with the first physical routing bridge; receiving a multicast packet at the virtual routing bridge from one of the physical routing bridges; and distributing the multicast packet according to either the first or the second distribution tree thereby preventing looping. | ||

| 主权项 | 1. A method for providing virtual link aggregation (vLAG) in a transparent interconnection of lots of links (TRILL)-enabled network, the method comprising: creating a virtual routing bridge logically connected to a first physical routing bridge and a second physical routing bridge to form a vLAG group at an edge of the TRILL-enabled network; determining a first distribution tree linking the first physical routing bridge to every other routing bridge in the TRILL-enabled network in a non-repeating fashion, ending with the second physical routing bridge; determining a second distribution tree linking the second physical routing bridge to every other routing bridge in the TRILL-enabled network in a non-repeating fashion, ending with the first physical routing bridge; receiving a multicast packet at the virtual routing bridge from one of the physical routing bridges; and distributing the multicast packet according to either the first or the second distribution tree thereby preventing looping. | ||
