Abstract: A device receives network information associated with a network and server information associated with one or more server devices, wherein the network is associated with a network device and the one or more server devices. The device generates, based on the network information and the server information, an encapsulation profile for a tunnel encapsulation path and a route profile for the tunnel encapsulation path. The device provides, to the network device, the encapsulation profile for the tunnel encapsulation path and the route profile for the tunnel encapsulation path, and provides, to the one or more server devices, the encapsulation profile for the tunnel encapsulation path. The tunnel encapsulation path is provided between the network device and the one or more server devices, via the network, based on the encapsulation profile for the tunnel encapsulation path and the route profile for the tunnel encapsulation path.

Abstract: A network device receives a packet with a multicast nexthop identifier, and creates a mask that includes addresses of egress packet forwarding engines, of the network device, to which to provide the packet. The network device divides the mask into two portions, generates two copies of the packet, provides a first portion of the mask in a first copy of the packet, and provides a second portion of the mask in a second copy of the packet. The network device also forwards the first copy of the packet to an address of a first egress packet forwarding engine provided in the first portion of the mask, and forwards the second copy of the packet to an address of a second egress packet forwarding engine provided in the second portion of the mask.
