1. A method comprising:
receiving, at an outer router of a switching device, a plurality of data packets from a plurality of source devices;
sending, from the outer router of the switching device, the plurality of data packets to one or more input ports of an inner router of the switching device;
routing, by the inner router of the switching device, a first set of one or more data packets of the plurality of data packets to a first output port of the outer router via a first output port of the inner router based on a first assigned security domain and a second set of one or more data packets of the plurality of data packets to a second output port of the outer router via a second output port of the inner router based on a second assigned security domain;
transmitting, at the first output port of the outer router, the first set of data packets received from the inner router to a first destination device; and
transmitting, at the second output port of the outer router, the second set of data packets received from the inner router to a second destination device.
