- two wans
- lots of vlans
- 32vcpu hypervisor with gpu passthrough
- 25gbps san running off the nas
Everything I do is mostly with VMs, the hypervisor is diskless pxe booting off the SAN. I’ve been cleaning up my lab, it used to be a plank of wood https://discuss.online/post/44690398
There is a nanokvm hanging off the hypervisor (rs232,atx header, hid) which makes remote rebuilds quite painless. I love my inexpensive nanokvm.

What does your homelab look like?

Well, yeah. VLANs work at layer 2. What you are routing is the subnet you assigned to each one.
I just have never heard the term “cross routing” in my 30 years of networking.
Fair enough - how would you describe it?
I would just say routing.
It’s most common to associate a vlan with a subnet for sanity, so i think “routing vlans” would be understood.
