Link connection between two Virtual Router on SRX220

Hi all,

My scenario is seperate SRX220 to two Virtual Router :

Host 1 --> ge-0/0/1.0   ---SRX220---  ge-0/0/2.0 <-- Host 2

From Host 1 traffic can reach to Host 2 and reverse. But with series SRX220, logical lt- interface do not support, so do have any solution to connect two VRs? 

Can i use physical connection between two VRS by using two ports for each VR? What interface can support?

Or, Rib Groups can route traffic between them?

The other scenario is create one VR and route traffic between VR and master routing-instance.

Is it in the same solution?

Many thanks!
