Continuous Router for Open Networks

[mynkpl1998]

Hi, I am trying to create an open-network as shown below. It has two in-merges and a long highway. Traffic can enter from edge_0 and ends at edge_2. However, I want to re-route the vehicle from edge_2 to edge_0 as soon as they reach the end of the edge_2.

I tried to use ContinousRouter to re-route the vehicles. However, that throws me an error saying no edge is defined between node-1 and node-4. Hence, Is there any way to re-route vehicles to starting position in open-networks?

Thank you.
