A process is implemented by a network device for enabling the provisioning of explicit trees in a network by reporting link aggregation group (LAG) configuration information to a path computation element (PCE). The network device implements a LAG module and an intermediate system-intermediate system (IS-IS) module that includes an IS-IS path control and reservation module (ISIS-PCR). The process includes reporting LAG configuration by the LAG module to the IS-IS module within the network device, sending a link state protocol data unit (PDU) (LSP) with the LAG configuration in a LAG sub type length value (TLV) by the ISIS-PCR, receiving, by the IS-IS module, an explicit tree that specifies at least one virtual local area network (VLAN) identifier (VID) to an aggregation link of the LAG assignment, and translating, by the ISIS-PCR module, the explicit tree into a LAG configuration, the LAG configuration specifying a conversation to aggregation link assignment.
