Yes

Implications if the forwarding address is set to .2 ? .10 avoids an extra
hop.
Implications if the forwarding address is 0.0.0.0 ? Extra hop + icmp
redirect ? I would have to run some debugs to see if .1 is sending
redirects. But by hearing you there seems to be more ?
Also .2 belongs to the 137.20.20.0/24 network which is part of the ospf
cloud. So I don't see how .2 can be reachable by another protocol.

Hehe, here I have no clue, would you shed some light ? I guess you are
seeing deeper than me ...
