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 class=""></o:p></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;" class=""><o:p class=""> </o:p></div><div style="margin: 0cm 0cm 0.0001pt;
