<p class="MsoNormal">Hi all,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We have used a couple of different DHCP servers for NBN IPoE sessions over the last few years, all talking to a RADIUS back end to look up the static IP address information based on circuit-ID (AVC). Initially we used a Mikrotik router,
but with a change in RADIUS server we need the DHCP server to use the circuit-ID as the AAA username, and the Mikrotik only uses the MAC address. I found that the DHCP server in our Cisco ASR could send the circuit-ID as the AAA username, but it has a “feature”
where AAA-based DHCP sessions have a maximum life (defined by Cisco AVPair session-duration, which has to exist and can’t be zero) after which the DHCP lease is forced to be released and has to be renewed from scratch. This causes a brief outage to the service
while they have no IP address, and causes some of our clients to failover to an alternate connection. After a chat with Cisco, I was told that it was by design and would not be changed or allowed to be overridden.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Our RADIUS server is FreeRADIUS, but it’s integrated with a customer management system, and it doesn’t allow us to use DEFAULT as the username and pick up the circuit-ID as an additional check.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Does anyone have any suggestions of a DHCP server that leverages RADIUS and can use circuit-ID as the AAA username, but is otherwise standard and allows unlimited renewals?<o:p></o:p></p>
