above i have two L3 switches.
ESW1 has vlan 10 and 20
ESW2 has vlan 10 and 30 (the same ten)
when i configure OSPF on both ESW1 and ESW2 it doesn't neighbor. I want OSPF to advertise vlan 20 to ESW2 and vlan 30 to ESW1
I did create a SVI for Vlan 20 on ESW2 and 30 on ESW3 so they could talk.
I just want to know if its possible to have OSPF advertising the unique Vlans to each other in area 0.

if its possible to have OSPF advertising the unique Vlans
: no, ospf does not advertise vlans. I guess you may mean "... to have OSPF advertising the unique subnets". That should definitely be possible. Please post your config of ESW1 and ESW2 so we can check what might be wrong. BTW your 3rd paragraph mentions ESW2 and ESW3, I suppose that is a typo?
