Layer 3 VLAN design for Aggregation to Core Routing

[bbextreme]

I am new to Extreme, coming from the Cisco world. I have read that there are no "routed" ports on EXOS/Switch Engine but you create a vlan and assign only that vlan to the ports. I have a lab where I have 2 cores, 2 aggs, and 2 access layer switches. I want L3 links for OSPF between core and agg switches. How would you go about this? Does this make sense:

vlan100 core1-core2 10.1.0.0/30
vlan101 core1-agg1 10.1.1.0/30
vlan102 core1-agg2 10.1.1.4/30
vlan201 core2-agg1 10.1.2.0/30
vlan202 core2-agg2 10.1.2.4/30

And then core1 might look like this:

core1:

create vlan core description core-routing
configure vlan core tag 100
configure vlan core add ports 12 untagged
configure vlan core ipaddress 10.1.0.1/30
create vlan core1-agg1 description core-routing
configure vlan core1-agg1 tag 101
configure vlan core1-agg1 add ports 1 untagged
configure vlan core1-agg1 ipaddress 10.1.1.1/30
create vlan core1-agg2 description core-routing
configure vlan core1-agg2 tag 102
configure vlan core1-agg2 add ports 2 untagged
configure vlan core1-agg2 ipaddress 10.1.1.5/30

That seems fine. Remember to "enable ipforwarding" to make all VLANs routable. You can do this per VLAN as well if you like, but that command enables forwarding on all VLANs at the same time. I guess you have the commands for the OSPF part, but here is one starting point: https://extreme-networks.my.site.com/ExtrArticleDetail?an=000082190
