On the one hand, it brings SD-WAN migration closer to Cisco customers. On the other hand, two preliminary indicators —  one-on-one conversations and Cisco’s refusal to participate in an SD-WAN test —  suggest enterprises should expect reduced throughput if they enable the SD-WAN capabilities on their routers.

By including the SD-WAN code with IOS XE, Cisco will provide a migration path for the more than one million ISR/ASR edge routers in the field. There’s been a lot of conversation as to whether or not SD-WAN is going to kill the router performance.
