Abstract
Embodiments of the invention relate to virtual link aggregation. One embodiment includes forming one or more virtual links using physical links connecting a first networking element, a second networking element and a third networking element. A first trigger status indication is used for blocking network traffic for avoiding traffic loops occurring over the one or more virtual links.
Claims15
A method for avoiding a network traffic loop in an absence of a loop avoidance protocol, comprising:
- coupling a first networking element to a second networking element;
- coupling the first networking element to a third networking element;
- coupling the second networking element to the third networking element;
- establishing a virtual link between the first networking element and the second networking element;
- and
- managing network traffic to avoid the network traffic loop based on whether the virtual link is successfully established.
A system for avoiding a network traffic loop in an absence of a loop avoidance protocol, comprising:
- a first networking element;
- a second networking element coupled to the first networking element;
- a third networking element coupled to the first networking element and the second networking element;
- and
- a traffic management module configured for managing network traffic to avoid the network traffic loop based on whether a virtual link is successfully established between the first networking element and the second networking element.
