Hello !
I'm new on this forum and a beginner in networking so sorry if I do something wrong !
I have this topology but I don't know why my switch 1 (the layer 2 on the center) keep this orange lights. Moreover, the computers in the same VLAN can't ping themselves through the layer 2 SWITCHs but trafic is going through layer 3 switch (For example, PC 1 CAN ping PC4 But the trafic doesn't go between the Layer 2). If i break the link between the switch layer 2 (on the center) and the multilayer switch, THEN trafic can go from PC 1 to PC4 normally.
I have one more question :
Do I have to create all the VLAN on ALL the switch or for example, VLAN 5 is useless on the right switch ?
I post you here behind all the commands I entered on the switch. Don't worry, my computers have a correct ip fitting with their VLAN.
Thank you very much for helping me !
