hello everyone !!!
i've have successfully configured LACP etherchannel on both layer 3 switches, i have assigned them both ip address of every vlan, i've enabled IP ROUTING and NO SWITCH PORT on the interfaces connected to the router. I have also configured OSPF but i still cannot PING from the Admin laptop (VLAN Gestion) to other VLANs but the opposite works...does anyone know what might be the problem ?
please i need HELP !!!
