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; in response to receiving a message specifying the fabric interface, storing, by the second virtual routing node to a context forwarding table of the second virtual node, the fabric interface as a next hop for the network destination; selecting, by the second virtual routing node and based on the context forwarding table and a context next hop in a first forwarding table pointing to the context forwarding table, the fabric interface for forwarding network packets destined for the network destination.
