<p class="MsoNormal"><span style="font-family:"Verdana",sans-serif">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.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Verdana",sans-serif"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Verdana",sans-serif">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.<o:p></o:p></span></p>

</div>
<p class="MsoNormal"><span lang="EN-CA">Hello, all.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-CA">I�m having difficulty finding vendors, never mind products, that fit my need.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-CA"> <o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-CA">We have a small but growing number of L2 (bridged) customers that have diverse fiber paths available, and, naturally, want to make use of them.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-CA">We have a solution for this: we extend the edge of our EVPN VXLAN fabric right to the customer premise. The customer-prem device needs 4x10G SFP+ cages (2 redundant paths, plus LAG to customer), and the switches we currently
use, Arista 7020Rs, are quite expensive if I�m deploying one one per customer. (Nice switches, but overkill here � I don�t need 40/100G, and I don�t need 24 SFP+ ports. And they still take forever to ship.)<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-CA"> <o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-CA">We use RFC7438 �6.3 �vlan-aware-bundle� mode, not �6.1 �vlan-based� mode, which limits our choices somewhat. I might be willing to entertain spinning up a separate VXLAN mesh using RFC7438 �6.1 (�vlan-based�) and static
VTEPs if it saves me a lot of pain.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-CA"> <o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-CA">However, I�m having trouble finding small & cheap<b><i>er</i></b> 1U (or even desktop/wallmount) devices that have 4 SFP+ cages, and can do VXLAN, in the first place.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-CA">Who even makes CPE gear with SFP+ ports? (Other than Mikrotik CRS309-1G-8S+IN / CRS317-1G-16S+RM, which are nice, but our policy requires vendor support contracts, so� no-go.)<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-CA"> <o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-CA">Vendors? Model#s, if you happen to know any?<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-CA"> <o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-CA">Reply here or privately, whatever floats your boat � any pointers appreciated!<o:p></o:p></span></p>
