Hi Phillip,
[terry@CCR2.NSW] /ip dhcp-server network> export # sep/06/2016 13:03:15 by RouterOS 6.36.2 # software id = CG4T-VJTQ # /ip dhcp-server network add address=180.181.80.0/20 gateway=180.181.80.1 netmask=20 ntp-server=180.181.127.1 [terry@CCR2.NSW] /ip dhcp-server network>
As above, the netmask stays nice and short, 4000 ip addresses per NBN CVC. "proxy-arp" will happily handle the issue of getting from AVC to AVC. A '/32' on an ethernet port for the WAN ip address is very much a dead end on all CPE I have tested. Also, of note, the ipv6 set up and M/C load from this deployment has also been far leaner. (ipv6 is trivial, add address to sub-interface with advertise=yes, add DHCPv6 with a Pool set up just for the sub-interface, voila: static ipv6 addresses and PD.) --- http://about.me/terry.sweetser On 06/09/16 12:33, Philip Loenneker wrote:
Hi Terry,
That's fantastic - I love seeing this kind of creative solution.
Just to clarify - are you copying the PPPoE IP addressing method by assigning a /32 to the CPE and specifying the network address as the gateway? So you would have a separate IP pool and DHCP server running on each interface.
I'd be very interested to see a more complete snip of the config if you are willing to share.
Does this seem to work on all CPEs, or do you only work with particular brands? I vaguely remember trying something like this a while back, but only Mikrotik CPEs seemed happy with it.
