Question about Bridging in Hub and Spoke (IEWB LAB 20 2.2)

Hi GS,

I am trying to bridge between two Spokes using CRB on the Hub. On the Spokes, I have
assigned their IP on the main interface and also defined a "frame map ip" statement, but
for some reasons I just can't ping across from Spoke to Spoke. On the Hub, everything
looks fine, and the spanning tree is in forwarding state for both interfaces.

Now if I change my configuration on the Spokes and use IRB with the IP assigned on the
BVI interface, everything works fine and I can ping from Spoke to Spoke.

Can anyone explain me why the following configuration does not work?

Thanks for your feedback,
Eric
