EVPN-VXLAN Service Types
by Graham Johnston 07 Jul '22

07 Jul '22

Good day, NANOG. I'm at the front end of an expected implementation of EVPN-VXLAN as the primary method to shift a network that is largely based on traditional Ethernet switching and spanning-tree to one that attempts to route traffic as often as possible, and where we want to separate the physical topology from the logical services. We are selecting EVPN-VXLAN as it seems to inherently provide for the Network Virtualization Overlay function, as well as routing since the entire underlay will be routed. As part of all the reading we are doing, and lab testing that is just about to commence, I'm trying to weigh the options around VLAN-based services and VLAN-aware bundle services. I know that the options aren't mutually exclusive, and that I can mix and match, at least I expect that this to be an option. In case it matters, our implementation will initially involve VTEPs based on a mix of Juniper QFX5100, QFX5110, QFX5120, and EX4650 switches, as well as MX. Yes, I do recognize the RIOT capabilities that aren't present in the QFX5100. From a basic FIB standpoint, we do believe that we are well below the quote limits in terms of hosts, routes, etc. I do believe that we've effectively weighed the use of VXLAN over MPLS. We currently believe that our use cases don't require some of the more advanced features and control knobs available in MPLS. We are also pragmatic and are trying to use the equipment that we have. We believe that the Trident ASICs in our devices are likely better suited for VXLAN than MPLS, despite the glossy datasheets quoting support for various MPLS features. Feel free to comment on this. For internal use, I can see the VLAN-aware bundles as advantageous to group all our own services together in a single MAC-VRF, treat ourselves as a tenant. I'm not clear yet if I should be concerned or not about each switch that is involved in this EVI having to populate all entries into FIB. Our own use cases are likely of a small enough scale that it wouldn't matter in comparison to the positive outcomes. As for customer use cases, I can't yet see an advantage to VLAN-aware bundles as our customers don't interact with multiple VLANs where those individual VLANs are terminating on individual VTEP ports. The customer use cases feel more like a traditional Q-in-Q type activity that has us treating them as single outer VLAN, and thus the VLAN-based service seems more appropriate. I'm flat out ignoring the middle ground option of VLAN-bundle service as I can't see anything that seems compelling compared to the other two. I know there is bunch that I don't know here. Am I focusing on the right two choices of the three service types? Do organizations regularly use both two that I am focusing on? How do you decide between the two models when provisioning an EVI? What gotchas await me with the Juniper equipment, or the Trident ASICs, that just aren't spelled out in the documentation? Answers to these questions and anything else you have to offer is appreciated. Thanks in advance, Graham

MediaCommerce has significant fiber and one of the largest networks within Colombia (not known to many outside of Colombia but those who operate in Colombia know them) and has good eyeball traffic within the country. They keep it local to not boomerang bank to Miami like many. They just installed a 100G POP in our new Tier IV data center in North Bogota, Colombia if you wish to connect with them let me know I can put you in contact with them. __ Manny Vivar HostDime Global Operations manny.v(a)hostdime.com <mailto:manny.v@hostdime.com> Mobile & WhatsApp: 407.467.2053 Skype: HostDime HostDime Global Corp. | www.hostdime.com <applewebdata://957C3374-181A-408B-BD20-C60548BC2CAB/www.hostdime.com> This E-mail is confidential.

I've explored Cogent, Lumen, and a local clled Telxius and results are all over the map. Is there a provider that's 'well peered' with all the locals?

FCC BDC engineer?
by KCI Dave Logan 06 Jul '22

06 Jul '22

Hi all. We operate a small regional ISP in Colorado, but no size is too small to ignore the FCC, as you all know. We're really struggling to find the required engineer for the filing, and we're small enough that we don't have an officer with engineering credentials. Any pointers in the CO/WY/NE/KS area would be great, on or off list. I sure hope we're the only org with this problem still, and all the rest of you are good to go. Thanks, dave -- Dave Logan Kentec Communications, Inc. 970-522-8107
