5K subscribers on a single port/handover VLAN for any modern BNG should not be a problem... Assuming you're sticking with IPoE/DHCP and you really want to split subscribers over multiple BNGs, I'd do something like this: 1. Present the backhaul VLAN to your N BNGs. You will need to use

With have the same gateway IP universal across routers - I can't really help with that, and if you've got a 'hack' that is working, perhaps stick with that. In regards to sharing load between mikrotiks, assuming you are using DHCP server (IPoE, since you specified no PPPoE) - my solution

I would love to use fq_codel, but right now we just use Mikrotik's red. The biggest hassle is that NBN shape down at 10ms which is pretty hard on the shaping software! Does make me wonder if we should ditch the Mikrotiks and use an open source solution. Damian On 9/13/21 10:33 PM, Dave

Wow. You live in such a different world than I. I would really like to better understand problems such as these, but where you are worried about arp at this low level, I worry about good queue and subscriber bandwidth management like that in this: https://github.com/rchac/LibreQoS (leveraging

2021-09-13 Thread Damian Ivereigh
Hi guys, We have built all our ISP infrastructure based on the NBN style doubled tagging of services - in other words each subscriber circuit comes through on it's own ctag. This makes separating everything really easy because we pipe each vlan through to different BNG's. However we are now
