Hi Folks,
Here is my int bundle 1 config, I have a DHCP server for MTAs and another one for CPE hosts.
interface Bundle1
ip address x.x.x.x 255.255.255.0 secondary
ip address x.x.x.x 255.255.255.0 secondary
ip address x.x.x.x 255.255.255.128 secondary
ip address x.x.x.x 255.255.255.192 secondary
ip address x.x.x.x 255.255.255.0
ip access-group 103 in
ip access-group 104 out
no cable arp filter request-send
no cable arp filter reply-accept
no cable arp
cable source-verify dhcp
cable source-verify leasequery-filter upstream 2 5
cable dhcp-parse option-43
cable dhcp-giaddr policy
cable helper-address 10.1.1.51 cable-modem
cable helper-address 10.1.1.233 host
cable helper-address 10.1.1.100 mta
end
I see leasequeries being sent to 10.1.1.223 for host CPE and it working fine. CPEs which did not get IP via DHCP server 10.1.1.233 are blocked.
However, there is no lease query being sent to 10.1.1.100 DHCP server for MTAs.
On our Casa and Arris CMTSs both CPE and MTA DHCP server are queired.
Does the uBR not query MTA IPs, if so suits me as I won't need to build another modified ISC DHCP server.
MTA IPs are not blocked. All our MTA IPs are given out by DHCP anyway.
Thanks,
Q.
