Abstract:
Routing of a traffic in a fabric network may be provided. A first traffic may be received at a first node. It may be determined that the first traffic is coming from a provider virtual network. In response to determining that the first traffic is coming from the provider virtual network, it may be determined that a first subnet associated with the first traffic is associated with a subscriber virtual network. In response to determining that the first subnet associated with the first traffic is associated with the subscriber virtual network, a first virtual network associated with the first traffic may be changed to the subscriber virtual network. A lookup for the first traffic may be changed to a first virtual routing and forwarding of the subscriber virtual network.
