Ahmed Medhat (a.medhat.h@gmail.com) is using SFC for his doctorate and found that the shortest-path algorithm causes a failure when creating a Rendered Service Path.
This problem should be fixed in both beryllium master and in stable/lithium.
Creating a simple RSP with the following simplified config:
SFC [TcpProxy, TcpProxy]
SFP [transport=mac]
SFs [2SFs]
SFFs [2 SFFs, 1 SF each]
When creating the RSP via RCP, I get the following errors in the log:
