Hi,
My CMTS config is attached. I want my CPEs to be able to communicate with devices which are in the same network as my gigaether interface. The subnet of my GigE interface is 172.16.1.0/24 and I want my CPEs to get IP addresses in the same range.
Below are the configs for GigE and Cable interfaces:
interface gigaether 15/0
ip address 172.16.1.46 255.255.255.0
no shutdown
no ip redirects
no ip unreachables
interface cable 3/0
cable bundle 1 master
ip address 192.168.6.1 255.255.255.0
ip address 192.168.5.1 255.255.255.0 secondary host
cable helper-address 172.16.1.45 cable-modem global
cable helper-address 172.16.1.45 host global
no shutdown
As soon as I try to change ip range for secondary host, I get the below error:
(config-if)#ip address 172.16.1.47 255.255.255.0 secondary host
% 172.16.1.0 overlaps with gigaether 15/0
What is the workaround to achieve this?
Thanks
I do not believe this is possible. The BSR64k is a layer3 device. Because of that, you cannot share IP ranges across Layer3 interfaces.
JB's right. it's a router, not a bridge cmts. by default they can get to it unless you have access lists to prevent it.
