The appliance triggers an alert if it detects an incompatibility between its attributes and those of the router. The appliance might be incompatible because of a specific attribute of a service group (such as GRE or Level-2). More rarely, in a multicast service group, an alert can be triggered when the "Auto" selection chooses a particular attribute with a particular router connected, but the attribute is incompatible with a subsequent router.
Following are the basic rules for the communication attributes within a SD-WAN Appliance.
For the Mask method, the appliance negotiates the “source IP address” mask. The appliance provides no mechanism to select “destination IP address” or the ports for either source or destination. The “source IP address” mask does not specifically identify any specific IP address or range. The protocol does not provide a means to specify a specific IP address. By default, because there is only a single appliance in the service group, a one-bit mask is used, to conserve router resources. (Release 6.0 used a larger mask.)
