First Claim
Patent Images
1. A device, comprising:
- a first routing instance; and
a second routing instance,wherein the first routing instance is implemented at least partially in hardware to;
receive, from the second routing instance, forwarding information identifying a next-hop;
receive, via a component of the first routing instance, network traffic;
determine, based on the network traffic and the forwarding information, an interface to a component of the second routing instance; and
provide, to the component of the second routing instance, the network traffic via the interface,the second routing instance to provide the network traffic to the next-hop.

Abstract
A first routing instance may receive, from a second routing instance, forwarding information identifying a next-hop. The first routing instance may receive, via a component of the first routing instance, network traffic. The first routing instance may determine, based on the network traffic and the forwarding information, an interface to a component of the second routing instance. The first routing instance may provide, to the component of the second routing instance, the network traffic via the interface. The second routing instance may provide the network traffic to the next-hop.

8. A non-transitory computer-readable medium storing instructions, the instructions comprising:
one or more instructions that, when executed by a first routing instance, implemented at least partially in hardware, cause the first routing instance to; receive, from a second routing instance, forwarding information identifying a first next-hop, the forwarding information identifying a component, and an interface to the component, of the second routing instance as a second next-hop; receive network traffic, the network traffic being associated with the first next-hop; determine, based on the network traffic and the forwarding information, the interface to the component of the second routing instance; and provide, to the component of the second routing instance, the network traffic via the interface, the component of the second routing instance to forward the network traffic to the first next-hop. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A method, comprising:
-
receiving, by a first routing instance of a device, forwarding information, the forwarding information being provided by a second routing instance of the device; receiving, by a component of the first routing instance of the device, network traffic; determining, by the first routing instance of the device, an interface to a component of the second routing instance; and providing, by the first routing instance of the device, the network traffic to the component of the second routing instance via the interface, the second routing instance to forward the network traffic to another device connected to the device. - View Dependent Claims (16, 17, 18, 19, 20)
