There are deployments where the Layer 3 interface on which OSPF operates is a Layer 2 interface bundle. Existing OSPF advertisements only support advertising link attributes of the Layer 3 interface. If entities external to OSPF wish to control traffic flows on the individual physical links which comprise the Layer 2 interface bundle link attribute information about the bundle members is required. This document introduces the ability for OSPF to advertise the link attributes of layer 2 (L2) Bundle members.
