Brian,
That's only true if you want to truly implement transparent LAN
services over DOCSIS. Separating the CPE data flow works with any
DOCSIS 1.0 or better modem since all of the tricky parts are in the
CMTS. We took a municipal cable network through 3 different CMTSs (3Com
and then a
One thing to be mindful of is that BSoD support may not be prevelant
in the installed modem base of your MSO. Replacing those modems would
be costly for someone.

We ended up using something like this to separate out the traffic at
layer 2 for each ISP:

Look at section 5.1.2 Multiple ISP L2VPNs
Basically the modems get DHCP & their config from the cable operator but
the CPEs
Hi Scott,
Thanks for the feedback,
yes this is how I understand it also, however I find it strange that the
Cisco platform designated as the future LNS will not accommodate the
DOCSIS 3.0requirements - not much collaboration. There is no roadmap for
introcducing PPTP on the ASR1K that I can s
Hey Michael,
Thanks for the feedback.
From the scenarios below, I think that option 3 would be more feasible,
i.e BSoD L2VPN, via pw. Our max expected number of sessions would not
exceed 10k, so probably not an hw limiting issue for us.
For option 4, we cannot accommodate this, as we are mov
Hi iptech
As others have said, early Cisco CMTS could do full bridging and/or PPPoE
termination, but newer gear is typically L3 style only.
For wholesale, the cableco could do one of these :
* L2 solution : Change your customers to configured as DOCSIS BSoD L2VPN,
and deliver you one dot1q VLAN
to elaborate on Valdis' reply, stick a fork in pptp, it is done.

Hey Ricky,
Yes that is the exact setup, the cableco bring the customer to us via
L2TP, and now want to do PPTP only.
I will keep digging on the ARRIS, which I have been told is a C4 system.
Although their website doesnt show much tech specs.
They are pushing for the L3 option since their CM
I've actually run into this specific problem and the issue your running
into is that at no time was PPPoE part of the DOCSIS specification. It
was supported on several CMTSs because the Cisco UBR shares much of its
OS with more mainline Cisco routers wh

As I recall from my reading of "the standard", there's nothing in there to
prevent any tunneling on top of the DOC
