Topic: FTTH with pppoe

[Jean-Philippe Pialasse]

Any of you have moved recently to fiber?
You might have seen that pppoe is probably used by your ISP, while not the most efficient approach.

They probably hide it with their own black box preventing you to so whatever you want with it.

From what I have seen in Canada, to get ride of their router / black box and having full speed, I had to:
- find the vlan they use (SME 11 accept thsi value on external interface)
- have a processor able to handle the load
- have a multi queue ethernet interface
- have pppoe handled in the kernel space rather than in the user space to handle cpu thread assigned with ethernet interface queue and handle the bandwidth (SME 11 now handle it this way)

What is you experience up to now with your provider ?

Hi Jean-Philippe,
Which is it ?
BELL, EBOX, Virgin, Videotron, ... ?
All, as you suggest ?

I am with Oricom, but as you might know most of fiber in Quebec/Canada is through bell using distributel.

Hi Jean-Philippe,
I help in an associative ISP (rezine.org) and the same (?) question was send by a futur « customer ». Question and answer in french because I don't want make a wrong translation :

TW : « Nous serions intéressés pour changer de fournisseur et Rézine semble totalement adapté à nos besoins.
Pourriez-vous me confirmer qu'il sera techniquement possible de connecter notre pare-feu à Internet en PPPoE via un transceiver ftth? »

OLB : « Nous fournissons généralement un routeur abonné avec OpenWRT qui porte l'IP publique mais il est également possible d'utiliser son propre routeur. La seule contrainte est que cet équipement fasse tourner un client DHCP sur une interface RJ45 connecté à l'ONT (équivalent du modem en xDSL). Il n'y a pas besoin de PPPoE comme en xDSL, c'est encore plus simple. Cette pratique est courante à Rézine et dans ce cas c'est bien l'équipement de l'abonné qui porte les adresses publiques (https://tickets.rezine.org/help/fr-fr/25-fibre-ftth/58-de-quoi-est-faite-mon-installation-ftth). »

Is that help ?
Bye

Great your ISP is getting ride of PPPOE which reduce the CPU overhead which increase a lot with higher bandwidth we see in fiber.

However here in Canada they tend to keep it.

Yet pppoe is used for accounting and to avoid ip conflicts on fiber links.
This is not the case for business connections using static ip configuration.
And yes, I had the unpleasant surprise of an ip conflict flip-flopping routes.

Does fiber provide a semi-static IP address like cable does? When my address changes occasionally, its easily tracked by my firewall and Cloudflare.

Really depends on provider and type of offer.

I was with cable for years with ip being kepts the same for months or years.


Bell in Canada for the FTTH and all the providers dpeending on Bell infra will get a pppoe and dynamic addressing. From my experience i will get a new ip on every reconection even if 3-4 times in the same hour. Also the ip could be in up to 5 different /10 or /12 ip blocks.

This not ideal on a lot of points.

Don't you have IPv6 address ?

nope
