Hi,
Why when I have below config: ge-0/0/44 { description test; unit 0 { family ethernet-switching { vlan { members vlan103; } storm-control default; unit 103 { description test; family inet { address 10.46.163.1/29; vlan103 { description test; vlan-id 103; l3-interface vlan.103; I cannot ping from EX4300 10.46.163.1 and I cannot ping 10.46.163.1 from server connected to ge-0/0/44 But when I add below: irb { unit 103 { family inet { address 10.46.163.1/29; and delete : vlan103 { description SGI; vlan-id 103; l3-interface vlan.103 ping works correctly. On EX3300, EX4200 and EX2200 I not need setup irb interface, why I need on EX4300 ?
