PPPoE BRAS: Cisco 7206 vxr.
VOIP gateways: Micronet SP5002
We have a periodic problems with pppoe connection from multiple Micronet voip gateways to Cisco BRAS.
The problem appears when Cisco 7206vxr is up about 20 days. But in the same time, pppoe connection passes with the same login from Windows XP.
After reboot Cisco 7206vxr, Micronet gateways connect to Cisco by pppoe.
I can't determine problem, because micronet voip gateways is in the different vlans, and they are get down synchronously.
I made wireshark dumps:
