I'm having a dig through my email archives to see if I still have the original test results but essentially we have to tunnel the DHCP requests, in order to correctly relay and receive a properly formed response, for our customers. I just mentioned this to a colleague and there may have been a few instances where we did not apply the workaround, yet the relay seemed to function correctly. Perhaps a difference between the different DSLAM manufacturers though this seems unlikely. We have been and are able to demonstrate, time and again that if the request is not tunneled to our PE, the end user LAN side equipment will not obtain a valid lease, from their central DHCP servers. Something we do not need to do with our EAD or EFM connected sites which have an identical configuration. Would be interesting to hear if other operators echo this or if indeed it seems to be just an oddity with our particular setup. -- Alistair Cockeram
