Folks,
I have a very simple design I configured it many times before but now
suddenly it is not working ,
I have two 3550 switches and I'm just trying to have them working as one
contain only vlan 2 (as edge switch) and the other one have another vlan
(vlan 3) but acting as Layer3 which routes between the two vlans , u
will find below the configurations of the two switches and as a test I
tried to ping from the down switch to the up switch vlan 3 interface but
no ping at all which lead to If I connected two PCs to these two
different vlans , I can't ping too
