Is there any solution for different CMTS's to use simultaneously the same public subnet ?
I am currently using CASA CMTS and Motorola BSR 64K.
Constantly i am facing a problem where every time i add a new CMTS or migrate a client from one CMTS to another the client is forced to change it's public ip address and doing so we have to add for each CMTS a different subnet.
Is this a thing that can be done at the dhcp server or CMTS configuration or should i configure a particular file to the modem ?
Any lead will help

Docsis enables you to use l2vpn setup in your configuration file of cable modem. That way you can aggregate vlan on a different router. I think is called BSoD Docsis. Take a look at it. This should solve your probem. If you have any additional questions please contact me on: jobacare@gmail.com
You could do some trickery with static IPs and dynamic routing protocols (basically, if you have a static IP on a CMTS, you create a host route for it, and that will be advertised up the network). BSOD won't quite work in this sense as you usually need a different VLAN tag for each modem. So short of going to a layer2 CMTS (which the carrier class ones are not), then the easiest thing to do would be to split your network up.
Double post sorry
