Re: 10G CPE w/VXLAN - vendors?

[Ryan Hamel <ryan () rkhtech org>]

I fully agree here too. That's why I proposed a "smarter" CPE to replace the standard appliances deployed on site, 
where the only thing changing is the configuration on the device itself, not product being handed off.

I think you’re probably overthinking this a bit.



Why do you need to extend your vxlan/evpn to the customer premise? There are a number of 1G/10G even 100G CPE demarc 
devices out there that push/pop tags, even q-in-q, or 802.1ad. Assuming you have some type of aggregation node you 
bring these back to, tie those tags to the appropriate EVPN instance at the aggregation point. Don’t extend anything 
but a management tag and an S-tag essentially to the device at the customer premise.



You can even put that management tagged vlan in it’s own L3 segment, or a larger L3 network and impose security. This 
way you’re not exposing your whole service infrastructure to a bad actor that might unplug your cpe device and plug 
into your network directly.

The reason customers ask that their site be part of the customer's Metro-E backbone is so that they can enjoy link 
redundancy without paying for it.

Operators will generally have east and west links coming out of a Metro-E site. Customers who single-home into this 
device only have their last mile as the risk. But if the operator drops a Metro-E node into the customer's site, and 
cables it per standard, the customer has the benefit of last mile redundancy, because the internal fibre/copper patch 
to the operator's Metro-E switch does not really count as a (risky) last mile.

Sales people like to do this to engender themselves with the customer.

Customers like to do this to get a free meal.

Don't do it, because customer's always assume that that Metro-E node that is in their building "belongs to them".
