Can I ping from VLAN to OSPF

[adamlee1811]

I have configured VLAN and OSPF with the diagram below. Between VLANs, I can ping each other but I can't ping to R2 in OSPF. So I wonder if VLAN can ping other autonomous regions?

Yes, as long as OSPF is configured correctly for area 0 and all the local vlans (10, 20, and 30) are added to the OSPF area 0, you should be able to ping end-to-end without any issues.

OK, so I must add SW into OSPF area 0 right ?

Not necessarily the switch, the subnets for vlan 10, 20, and 30 wherever they are located, they need to be added to the OSPF domain.

If the switches are layer-2 only, then most likely the subnets for the vlans are located on r1, r2, and r3.
