Comment 5 for bug 2056799

ok, I think I understand your concern now. Now the BGP driver (with default exposing mechanism) is based on kernel routing, so it requires routes on the kernel and vrf leaking to do so. That said, I think there are 2 solutions for this:
- We have the ovn driver, which instead of using kernel routing, uses ovn routing, so in that case eth0 can be completely isolated from the BGP nics.
- never tried this, but you could have vrf leaking to another vrf, and make all your advertisement in an specific vrf (instead of the default one). It may require some (I hope minimal) changes into the code base, but would be nice addition
