EIGRP default route not redistributed when VRF active

Hi there

problem should be simple to resolve. However, i could not succeed. I have a FlexVPN setup with hub & spoke design. I had to change the configuration from a nonVRF Design into a fullVRF (all interfaces belong to a vrf) design. Since then, the default route is not advertised to spoke routers anymore. Here are some outputs:

 I tried a whole class B range (as all our devices reside within) as well, but it didnt help. On the spoke side:

The thing is, it worked before is VRF'ed the hub router. But in my understanding i did everything correct. I hope someone else is spotting my mistake quickly. If you need more output, pls advise.

Help is much appreciated.

OK i just found this post:

It explains that you have to set a metric when redistributing static routes while using vrf's. As soon as i added a metric, the networks came up immediately.
