Dear All,
I need a help. I would like CMs and EMTAs in seperate subbundles:
interface Bundle2
no ip address
no cable arp filter request-send
no cable arp filter reply-accept
no cable arp
!
interface Bundle2.1
description CM-SUBBUNDLE
ip address 10.50.184.1 255.255.252.0
cable source-verify
cable dhcp-giaddr primary
cable helper-address 172.23.0.239
!
interface Bundle2.2
description MTA-SUBBUNDLE
ip address 10.143.184.1 255.255.252.0
no cable proxy-arp
cable helper-address 172.23.0.239
The CM is online.
The dhcp reply is:
Jul 5 17:24:55 dhcp-cm dhcpd: DHCPDISCOVER from 50:39:55:ab:76:b6 via 10.50.184.1
Jul 5 17:24:55 dhcp-cm dhcpd: DHCPOFFER on 10.143.184.97 to 50:39:55:ab:76:b6 via 10.50.184.1
If I put everything in a single subbundle it works....
Any suggestion would be greatly appreciated.
BR.

The way that this can be done is via dhcp, in dhcp you have to assign the modem/emta to the subnet you want. You also will need 2 dhcp servers 1 for cablemodems and one for hosts (CPE)
in your modem dhcp server you create a dhcp shared-network with both modem subnets in it, then using some criteria assign the modems to the correct subnet.
then on your host dhcp server you create two shared networks, one with the modem subnet and the subnet for cpes, and one for mta modems subnet and a subnet for the mtas
it may be possible to do on one server, but the config would be very unwieldy.
Many many thanks! I was banging my head with a single DHCP server...
