Hi Support, I have been goin through the forum for some time but have not been able to solve this problem.
Any assistance or guidance will be appreciated.
We have network with 1 core router  and multiple CCR-1009 routers deployed at sites which does the OSPF routing and MPLS/VPLS for pppoe users.
OSPF we are using PTP from 1072.
The OSPF routers are connected to CSS326 switches with vlans for pppoe users. Problem is at the PPPOE Server Router  all VPLS links flap randomly together. It drops for 3-5 seconds and then all users get connected. But causing packet drops to customers and inconvinience if on calls or IPTV.
I have also gone through the forum and modified the mtu configs, but there is no change.. every hour 3-4 times it flaps.
Attached is the diagram, if someone can shed some light.
