As with any network build, you have to make compromises. There are many
boxes I have not bought because they can't do something we consider basic.

Luckily, I've not been in a situation (yet) where I've not had an
alternative. But if that day would come, I'd make the hard choice.

In the 2000's, l3vpn's were more popular than l2vpn's.

For networks that sold a ton of l3vpn's, you'd have had to consider how
many l3vpn's you want to sell vs. how many Internet routes you want in
an Internet VRF.

Assuming some platforms still have such a restriction, it's too much
admin. for me. But again, that's just me, since several others have made
this work for them.

Fair enough.
