Are there any potential routing issues to watch out for when using mGRE interfaces on spokes. I need spoke-to-spoke connectivity. Obviously if I opt for p-pGRE interfaces then traffic from spoke-to-spoke will have to go via one of the hubs.
I understand there was a limitation in IOS whereby mGRE interfaces on spokes prevented it from learning many routes via the hub.
