Hi

'ifname' represents an interface associated with the route (i.e. one to
which the route aims), not the iface to which the route is announced by
RIP. When route is accepted for protocol, it is accepted for all
interfaces of the protocol (unless split horizon applies).

It would be a good idea to have separate import/export filters per
interface, but that is not supported now.

If you want better control, you could configure two protocol instances,
one for each interface. Such setup has some limitations and may require
some tweaking, but should work.
