[ibr-dtn] Bundle deletion upon receive receipt

Hello all,

I currently have a 3 node 2 hop DTN setup: A-B-C with epidemic routing. When a bundle from A is delivered to C, the bundle is not deleted from storage on A, but is deleted at B. This causes a continuous buildup of bundles at A. When I turned on requestReceptionReport(), nothing changed. Is this normal behaviour? Under what conditions will a bundle be deleted from buffer at A when it is delivered to C via multiple hops?

Thanks, Harsha
