One more bug router/switch never can ping PC first, only after PC start ping. Too old bug.

I found solution.
SPB:
interface GigabitEthernet0/0/0.4
  arp broadcast enable

MSK:
interface GigabitEthernet0/0/1.4

 arp broadcast enable

Reason: "Because subinterfaces for VLAN tag termination discard broadcast packets after receiving the packets." Solution: "Just enable ARP broadcast on subinterfaces"
