Abstract
In one embodiment, techniques are provided to generate a Border Gateway Protocol-Link State (BGP-LS) advertisement message comprising information configured to indicate topological information associated with a Layer 0 (L0) network, where the topological information includes information for connectivity within the L0 network that is available to a Layer 3 (L3) network. The advertisement message is sent to a node in the L3 network. The message sent from the L0 network is received at the node in the L3 network. The topological information in the message is analyzed in order to determine connections available to the L3 network, yet within the L0 network. A connection request is sent from the node in the L3 network to the L0 network and connections between the nodes in L3 network are established using available connections in the L0 network.
