[c-nsp] PPPoE Migration to DHCP

[Pshem Kowalczyk]

Hi,

We have not encountered any particular issues running both technologies at
the same time. Some things to consider though:
- IP addressing
   for DHCP Cisco recommends running an external DHCP server,
   for PPPoE you can get away with running pools on the BNG
- Session state detection
  PPPoE has build-in keepalives, DHCP uses lease renewal. In our experience
xDSL circuits are better off with PPPoE,
- in redundant BNG setup - how the IPoE/DHCP sessions are steered to one
BNG or the other

kind regards
Pshem

​Thanks

Pshem for your kind reply.

Actually it is a future implemetation i guess as we are ISP and we would
deploy triple service maybe in the near or far future but that is not yet
confirmed. PPPoE is work well with us at the moment but i am just asking
for you guys view.

I think much of the questions answered by your one line below,  PPPoE/DHCP
should co exist for the benefit of both technlogies.

Any chance you would share your view on BRAS config for both co exist

Hi,

What's the specific question? We run both PPPoE and IPoE/DHCP in our
network maintaining feature parity between both technologies. Except for
the different ways to configure the BRAS/BNG the rest of the software stack
is pretty much the same.

kind regards

Hi

Any chance someone have implent and experienced dhcp in their ISP with
volume based charging of the customer based on how much they use over time.

It would be more interesting if someone migrate from pppoe to dhcp.

Hope this makes sense.

Let me know any hints or links that you might think it is useful.

Thanks.
