From what I know each router has to have its own certificate signed by the CA (certificate authority). In each certificate the subject field uniquely identifies the equipment (in your case router) it is meant for. I don't think there is a way for the CA to issue a certificate usable on multiple devices
Thanks for your response. I was able to perform this however there are some drawbacks since you are using the same certificate signed by the CA, there will be no identity between the devices involved. Aside from that, there is an alarm being generated but is not traffic affecting.
