Classification: CPC H | IPC H

Claim 8:
9. A non-transitory computer-readable medium storing a set of instructions, the set of instructions comprising:
one or more instructions that, when executed by one or more processors of a network device, cause the network device to:
determine, based on a routing table, a first routing path, based on a first cost metric, associated with a first security classification from the network device to another network device;
determine, based on the routing table, a second routing path, based on a second cost metric, associated with a second security classification from the network device to the other network device;
determine, based on the routing table, a third routing path, based on a third cost metric, associated with a third security classification from the network device to the other network device,
wherein the first cost metric, the second cost metric, and the third cost metric are different, and
wherein the first cost metric, the second cost metric, or the third cost metric is one or more of:
an interior gateway protocol (IGP) cost metric, or
a traffic engineering (TE) cost metric;

receive network traffic that is destined for the other network device and that is associated with a particular security classification, of the first security classification, the second security classification, or the third security classification; and
forward the network traffic based on a particular routing path, of the first routing path, the second routing path, or the third routing path, that is associated with the other network device and the particular security classification.
