You may have surmised from the lack of response, the answer is no.
DLEP is a new Radio Aware Routing (RAR) protocol. There is some good news. Not only do you have the RFC 8175 as a requirements baseline, MIT Lincoln Laboratory has released a reference implementation on GitHub (https://github.com/mit-ll/LL-DLEP).
For an overview of the technology, Cisco has released an "At-A-Glance" (https://www.cisco.com/c/dam/en_us/solutions/industries/docs/gov/aag_dlep.pdf) and has provided a configuration guide, indicating the attributes most likely to vary. (https://www.cisco.com/c/en/us/td/docs/solutions/GGSG-Engineering/15-4-3M/config-guide/Configuration-Guide.html) or (https://www.cisco.com/c/en/us/td/docs/solutions/GGSG-Engineering/15-4-3M/config-guide/Configuration-Guide.pdf).
Note: The configuration guide covers all of the areas you want to simulate (OSPFv3, DLEP) and covers technologies you might want to compare against (EIGRP, R2CP or PPPoE).
I do not know if Riverbed has plans to develop models for this evolving wireless technology. You may need to develop your own model.
Thank you for your answer, yes you are right, my interpretation of missing answers was that the support for DLEP is not implemented.
I have seen the documents that you are referring to but the Github repository was new to me, thanks.
Basically, I want to assess the utility with the new protocols in a router-radio relay network. My idea is to do a baseline with our current setup with cisco routers (OSPFv2) and compare with new protocols (OSPFv3-DLEP). My idea is to do two user cases, one to measure the time for rerouting when one link fails and one with QoS for video when a link has a high bit error rate.
The setup could look like this
Router - Modem (DLEP) - Connection emulator (High BER or link fail) - Modem (DLEP) - Router
Thanks once again for your answer, I think I have some reading to do before setting up this lab.
