Oh man I wish that were wholly true... Satellite/VSAT has another very very important attribute: it's not subject to the whims of the local government or regulators. So when there's an election or some unrest or coup or the prime minister has very bad flatulence, and some person says "turn off the Internet," your non-terrestrial connection is there so that you can continue to do business. Right now I'm in the middle of a project installing more than 300 VSATs, replacing an incumbent provider, and the rationale for all that money and all that equipment and all that work is "the bits must flow." (Plus, there are also still many places outside of capital cities in the world where the Internet is truly awful and if you want bits, you have to bring your own) jms -- Joel M Snyder, 1404 East Lind Road, Tucson, AZ, 85719 Senior Partner, Opus One Phone: +1 520 324 0494 jms(a)Opus1.COM http://www.opus1.com/jms

4G / 5G backup
by Baldur Norddahl 12 Jul '20

12 Jul '20

Hello I am looking for a CPE product that can use the 4G and soon 5G cell network as backup to our fiber. The product should create a VPN back to our network, so the customer can keep his IPv4/IPv6 address and all other services running as normal except maybe at a lower speed. I imagine this CPE router could use BGP to announce itself through both the fiber and the cell backup. Are somebody doing this and what can you recommend? Thanks Baldur

IPv6 over vxlan+evpn Arista?
by David Hubbard 10 Jul '20

10 Jul '20

Hi all, was curious if anyone is doing dual stack v4/v6 over Arista’s implementation of vxlan / evpn (the inter-data center transport would be v4)? They have plenty of references for v4 deployments but had to check on v6 support, which can make one nervous; they did confirm it’s supported. Looking to leverage it as a way to migrate a dual-stack data center without re-addressing. Thanks, David

L2VPN/L2transport, Cumulus Linux & hardware suggestion
by Jürgen Jaritsch 09 Jul '20

09 Jul '20

Dear folks, have anyone already tried to run VXLAN/EVPN + Bridge Layer 2 Protocol Tunneling on Cumulus Linux as an replacement for classic MPLS L2VPN/VPWS (xconnect, l2circuit, VLL) ? I need to provide transparent Ethernet P2P virtual leased lines to my customers and these have to support stuff like LLDP, STP, LACP, etc. The transport L2 network is not THAT big: max hops between VTEP is 4. Anyone have suggestions for the below hardware request? #) 1-3U L2/L3 box #) 48x SFP28 / 1/10/25G #) 6x QSFP28 / 100G #) VXLAN/EVPN with L2 tunneling support or #) MPLS VPWS/l2circuit #) Dual PSU thanks & best regards Jürgen

CGNAT Opensource with support to BPA, EIM/EIF, UPnP-PCP
by Douglas Fischer 08 Jul '20

08 Jul '20

We are looking for a CGNAT solution open source based. Yep, I know that basic CGNAT can be done with iptables / nftables, or PF / IPFILTER / IPFW. But I only know Open Source CGNAT recipes with predefined public-ports <-> private IPs mapping. What It brings two types of issues: A - The need to overprovision the number of private IPs (Considering Multiple BNGs behind the CGN). B - The inability of those basic recipes to deal with incoming auxiliary connections of p2p protocols (mostly used by games). Te market solutions that I've dealt with solves those issues beautifully. a - Bulk-Port Allocation - BPA, avoid the need overprovisioning private address that is not being used, and give us an excellent rate between public IPv4 Address vs Private IP Address. b - The support of a framework of protocols(Ex.: UPnP, PCP, EIM/EIF, NAT-PMP, etc...) ensure an acceptable quality of experience to end-users. But, the market solution brings also some down-sides... - The cost, evidently. - The need for detouring the traffic that doesn't need CGNAT(Internal CDNs, Internal Servers, etc), to stay on the license limits of those boxes, sometimes brings some issues. So, I and some friends are(for a long time) looking for an OpenSource solution that can give us something near what the market solutions give. Any of you guys ave some suggestions for that? P.S.: Yes, I know that IPv6 is the only real solution for that, but until there, our customers still want to access a lot os p2p content(mostly audio in game rooms, sip calls, and things like that.) P.S.2: Yes, I also know that 464 could be a good possibility, but is not possible in this scenario. -- Douglas Fernando Fischer Engº de Controle e Automação
