Changing from hub to spoke

[Adrian4]

Hello,

We have a organisation with 30 or so sites. Currently they are all configured as hubs for a full mesh topology and we want to move to hub and spoke.

My question is, what is the impact of changing a site from a hub to a spoke? 

Obviously all non hub VPNs will drop but what about the spoke sites general connectivity? 

At the moment, all open internet traffic goes straight out to the internet from each site. Only internal traffic that needs to go to other sites gets passed along the SD-WAN. - Would that continue if we changed to spoke, or would it suddenly try to pass all its traffic through the hub?

Just trying to to identify any gotcha's before they happen 😛

thanks!

When you set it to spoke you have to select a hub. Then you can set another option to learn a default route from that hub if you want all traffic to use the autovpn. If you dont select that default route option your internet traffic wont use the autovpn

Spoke to spoke traffic changes to being routed via a hub.  It doesn't get dropped.

The behaviour would remain the same.
