I'm working on my VMUG Advantage home lab, now with NSX!
My home router is a Sophos UTM, so it supports OSPF.
DLR <-- area A --> ESG <-- area B --> Sophos UTM
The DLR and ESG are exchanging routes, as are the ESG and UTM. How do I get the UTM and DLR to know that they need to reach each other through the ESG?
Looks like "route redistribution" from OSPF to OSPF is grayed out.
Thanks.
So we have two areas in the configuration . Firstly you need to make sure Interface to Area mapping is correct . Going via your topology it would be like this
DLR Transit (Area A)
ESXG Intenral(AreaA)
ESXG External(Area B) and UTM Internal Internal (Area B) -I would configure this as the backbone area -0
Once after that we need to update dLR which subnets need redistribution -so select Connected and learner protocol OSPF -

I have those as that except Area A = 23 and Area B = 28
Is the backbone area special in some way?
Changing it to the backbone area worked.
