Hi guys,see the image above,considering that the link between sw1 and DSW1 has failed,DSW1 and DSW2 are l3 switches with SVI's and the vlan 30 wants to communicate with a host on vlan 10,vlan 30 will send the data for the gateway wich is DSW1,and DSW1 will drop the packet because doesnot know the subnet of vlan 10 anymore,one link (L2 or L3) between DSW1 and DSW2 would solve this problem on this case,am i sure about all this?
