Device 1 is on VLAN 2 (192.168.2.25) - plugged into Aruba switch (port ge 0/0/1)
Device 2 is on VLAN 3 (192.168.3.25) - plugged into Cisco switch (port fa 0/3)
Pings:
- from device 1 I cannot ping device 2 or Aruba switch
- from device 1 I can ping all three router interfaces and cisco switch
- from device 2 I cannot ping device 1 or Aruba switch
- from deviec 2 I can ping all three router interfaces and cisco switch
Not sure why I can't ping from device 1 to device 2, device 2 to device 1 or from either device to Aruba switch?
