Okay - that's what the other people told too and seems to be the right way.

... But is is getting more complicated. In fact I'm only using one vrf and
the default instance and want to export routes from the default instance
into the vrf.

Would you have an example how to accomplish an export from the default
instance into a vrf for me, please?

Thanks,
Gunther
