Abstract:
1. A method comprising: configuring a plurality of multi-topology routing (“MTR”) topologies in a network by adding one or more respective Internet Protocol (“IP”) Security Protocol (“IPSec”) routes to each of the plurality of MTR topologies; receiving network traffic of a first type at a first node in the network, the network traffic being destined for a second node in the network; selecting an MTR topology of the plurality of MTR topologies based on the type of the received traffic, the selected MTR topology to be used for transport of the traffic in the network from the first node to the second node; forwarding the traffic from the first node to the second node in the network over the selected MTR topology using at least one of the one or more respective IPSec routes added to that selected MTR topology; wherein the method is performed by one or more computing devices.
