I’m looking into switching from 1gig Ethernet in the network to at least 2.5gig for my core switch. I’d love to be able to do intervlan routing with a layer 3 switch but am unsure whether it’s worth my time and effort.

Should I instead just setup my OPNsense with LAGG of 3-4x 1gig ports and just continue routing VLAN traffic with it?

I know it’s not optimal, but I’m also looking to do things relatively within budget. I don’t want to spend $500+ on a 2.5/10gig layer 3 switch… especially but if that’s my options I’ll consider it.
