What IP address should be set as the system-ip address in the vManage template?
1. The IP provided by the wireless sim provider?
2. The IP to assign to the ENET interface of the CG522-E? ( for local management )
3. The IP to be used on a SD-WAN VPN ( for in-band management )? how can you assign the VPN as well?
Thanks in advance

Hi,
system IP is like router ID from traditional routing protocols. You can set whatever you want. This is just unique number per SD-WAN node, but just in IP format (a.b.c.d).
Normally, when you design your overlay network (i.e SD-WAN), you select IP-based numbering for each region/site/router.
For example, controllers use 1.x.y.z format where x is regions y is controller type , z is controller number
For routers, you use 1.a.b.c format where a is region, b is site, c is site router number.

So basically the CG builds a TLS tunnel with vManage over the Internet and the system-ip is like the loopback IP of the CG and just needs to be unique within the controller complex.
Thank you very much,

System-IP is not used for connectivity, that's why it can be arbitrary (but just unique). It is just used as parameter during negotiations.
Tunnel-enabled Transport (VPN0) interfaces are used for connectivity to controllers and other routers from local device.
