Remember r2 has no IP address. That's the key to the question and I don't
think the question requires you to put an IP on r2 interface connecting to
port 2. I see it as 2 Vlans assigned the same subnet. The only way is to
configure a trunk on r2 interface and create 2 subinterfaces belonging to
vlan1 and vlan2 and then bridge these two.
Just thinking aloud I guess.

Once you assign an IP address to a VLAN you can start thinking of the L3
switch as a many-ported router. The switch can route between the default
vlan (vlan 1) and vlan 10 as follows:
R4 140.10.1.4 (vlan 10)
R6 140.10.1.6 (vlan 10)
int vlan 10 140.10.1.7 (vlan 10)
**switch routes between vlan 10 and vlan1**
int vlan 1 140.11.12.7 (vlan 1)
R2 140.11.12.2 (vlan 1)
Here's the relevant link in the 3550 documentation.
