Thank you for your answer, but a netns is different from a VRF. The
namespace is a total isolation container, unsuitable for my needs.
AFAIK, a single process cannot have sockets in different namespaces,
while this is totally possible with a VRF.
That being said, there is a similar 'ip vrf exec' command in the latest
(5.x) branch of iproute2, unfortunately it doesn't run properly on my
default Debian 9.9 kernel - seems it needs some CGROUP extensions that
are not part of the default build. Will have to experiment some more.
