Re: 10G CPE w/VXLAN - vendors?

Not sure how much of "CPE" it needs to be, but for example the whole Cisco Catalyst 9K product line (including the smaller C9300 switches) support the whole EVPN/VXLAN stack). A similar set of products exist on the Arista side (e.g. 7xx switches) as well as Juniper EX4400 products... On Wed, Jun

Most (if not all) of Israel's capacity is served from Europe. There is no real reason to serve users in Israel from India... You should most likely be using instances in Frankfurt or London for best results. On Mon, May 25, 2020, 12:46 Martijn Schmidt via NANOG wrote: > Hey John, > > Do you

Re: Consistent routing policy?

Ben, To make it a bit cleaner, you most likely want to send your aggregate (/21) to all service providers, and then if you choose to deaggregate and create more specific advertisements for traffic engineering purposes, you just advertise the relevant longer prefixes (/22's for example) on the

Mark, I made sure with the BU, and they confirmed that ASR1001 with 8GB RAM can handle 1M routes per the data sheet. The difference between ASR1001 and ASR1002 with EFP5 is due to a more powerful integrated RP on ASR1001 (Not really RP2, but closer to RP2 than RP1) and more memory (4GB is max on

Re: I don't need no stinking firewall!

What is nice about load balancers is that if you design your solution correctly, you can scale them in a very nice way. Things like direct server return, where only the requests hit the load balancer, but the replies (which are usually larger) just route back directly to the client can free up

Rens, Does not sound like the symptoms for what I want to write about, but this is something you need to consider in any way: When you run sub-rate links (i.e. 1GE interface with really 155Mbps as the service) you need to make sure that you do not try to push more traffic than the link can take.

Re: Broadband Subscriber Management

You need also to remember that in many cases the DSL link is not provided by the actual ISP. In many cases this is a wholesale scenario which uses L2TP to forward the PPP session from the telco/DSL provider to the ISP. In many cases there would also be another L2TP hop to another sub-ISP/customer.
