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 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

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

Ray,
Yes PITA indeed.
Our 7200 are G2, but we were still planning on moving away from them.
I presume you guys are staying on the 7200s meantime, to accomodate the
PPTP requirement?
Thanks,

Hello,
Is there anyone with clue from UCSF on-list? Or if someone knows how to
put me in contact with them, that would be great.
We are not able to query their DNS servers from our network. We've got

Thus far, their response has been to manua

I am querying them OK. I am in US AZ. I am also able to reach
manana.garlic.com.

Ditto on that from TWTC in Milwaukee, WI.

Looking for experiences regarding their DNS hosting services. Anyone
have a story to share? Off-list replies would be great.

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.

Hi all,
I am looking for literature on the (monetary) costs of misconfigurations in an
operational ISP network. Are there any such studies I can benefit from?
In a larger context, are there any thorough studies exploring the cost of
building and running a large ISP network?
Best,

Hi Murat,
I never saw any literature about this topic. But I think it is not too
difficult to calculate (or estimate).
A misconfiguration will, at least, impact on two points: network
outage and re-work. For the network outage, you have to use the SLAs
to calculate the cost (how much you lost fro

Hi Darius,
You are right. The lost of a customer due to those things. However, I
would classify this as an unknown situation (in terms of risk
analisys) because the others I mentioned are possible to calculate and
estimate (they are known). But it is very hard to estimate if a
customer will cancel

I was not aware of this limitation. Android and other Chrome devices do not
have issues like these. Wow.

Quantifying the business costs would be very complex.
