A new WAAS installation is planed. The customer has 3 sites with one WAAS on each. On each site, there is no core layer. The L3 device is the ISP router. So, the WAAS will be plugged via inline interfaces between the ISP router and a switch. The WAAS will received all L2 broadcast from the LAN. There is no L3 point-to-point dedicated network between the router and the switch.
Is this scenario could be an issue ?
