I got it working now - The configs are below...
Just oine problem (I don't know if this is related to my Fastethernet on
R5), but...the interface resets as soon as I do changes on it, and after
that only a reload of R5 and R6 will make it work again!
Any ideas why this is happening?
Also...If I wan't to run IPX normally routed on the 2 Vlan's I reckon I just
have to give the network statement on the subinterfaces on R6!
Anyway...thanks for valuable input!

I tried your scenario last time, with a router in a stick to bridge
between VLANs. I got a working config to bridge between
the two VLAN, at the time either "bridge 1 protocol ieee" or
"bridge 1 protocol vlan-bridge" doesn`t have any different result.
Both commands still bridge the two VLANs.
I didn`t investigate any further what are differences if any with
a "vlan-bridge" command. Hope that someone would tell us
what this command for.
