Fusion Router can have SD-WAN functionality also enabled

[subin_k@hcl.com]

Hi Team,

I am working on a customer scenario and trying to proposed SD-Access Solution, after reading several articles, i understand fusion router is required depending upon the situation if need to have communication between VRF and GRT or between host connected to SD-access environment and host connected to traditional Environment.

Now the question is if Fusion router is required, can i also enable sd-wan functionality also on the same device, if the device supports. Also this a supported/recommended design

As of today, Fusion router is a mandatory requirement. its needed perform VRF route leaking between user VRFs and Shared-Services (like DHCP, DNS etc), which may be in the Global routing table (GRT) or another VRF.

I have not tried ever using Fusion as SD-WAN device. I would recommend you to also put this question on SD-WAN community page as well.

Subin K,

A Fusion device just needs to support VRF-Lite and speak the same routing protocol as the border is using for the VRF handoff. As long as the SD-WAN router can do this, then it is just a matter of routing between the traditional and SD-WAN environments.

Cisco is working on an orchestrated handoff between SD-Access and SD-WAN (Viptela) using cEdge as both the SD-Access Border and SD-WAN edge. This would eliminate the need for the fusion, but such an orchestration is not there yet. This was presented in the most recent Cisco Live event that ended last week. Within 2 weeks the sessions and videos from that even will be posted on ciscolive.com in the On-Demand library (free for all to access), at which time you can get the content and/or watch the video. The session you want is BRKCRS-2818.

Hi Scott,

This was a useful information, any idea by when this feature would be coming in and we don't have to consider any fusion router going forward
