Abstract: In some examples, a method includes selecting, by a first virtual routing node of a single-chassis network device having a plurality of forwarding components and a plurality of fabric links coupling respective pairs of the plurality of forwarding components at respective fabric interfaces of the plurality of forwarding components, a fabric interface of a forwarding component of the plurality of forwarding components that has an egress interface toward a network destination and that is associated with the first virtual routing node; advertising, to the second virtual routing node, the fabric interface as a next hop for the network destination and a label for use in establishing a transport label switched path (LSP); and computing, by the second virtual routing node, a path for the transport LSP to include the fabric interface, and establishing the transport LSP along the computed path.
