Least Disruptive AF Assignments in TRILL LAN Adjacencies

摘要

A methodology is described for achieving efficient forwarder appointments. Such efficient appointment may provide an equal load on each participating routing bridge in the TRILL LAN. Load may be viewed as the number of VLANs for which a given node is an appointed forwarder. Furthermore, efficient appointment may be executed with a minimum of traffic disruption. Minimal disruption may be ensured by forwarder appointments by moving a minimum number of VLANs to ensure an equal load on each participating routing bridge.

1. A method comprising:
adding a first node to a TRILL LAN, the TRILL LAN comprising a first number of nodes and a first number of VLANs from an enabled VLAN set; and reassigning a plurality of VLANs from the first number of VLANs to the first node from the first number of nodes, wherein the plurality of VLANs is equal to a determined number of VLANs enabled by a designated routing bridge divided by a determined number of nodes prior to adding the first node.
