The Virtual Private Network Fast Re-route technology is based on the general networking with CE dual homing deployment.To enable fast convergence in case of active PE fault,that can apply VPN FRR to the remote PE and select the remote CE routes needing protection based on the route matching policy.The conclusion is that the VPN FRR is a simple,reliable,and easy-to-deploy technology that can effectively shorten the down time of end-to-end services in case the PE equipment in the CE dual homing network breaks off.
