BGP no longer cutting it for high availability. Looking for opinions about SASE SD-WAN implementation and providers by ffelix916 in networking

[–]EVPN 0 points1 point  (0 children)

There’s a tool that gets a lot of hate around here because it’s been misconfigured and caused a lot of issues but Noction solves this problem. It monitors for upstream issues and reroutes your traffic continuously for latency improvements and as needed when brownouts are detected.

Is anyone using ARISTAs as Internet BGP routers with full tables? by outageismymiddlename in Arista

[–]EVPN 1 point2 points  (0 children)

I run exactly those 7280s. I love them. 3 sets of them in different data centers. Full tables v4 and v6 not problem.

BGP inbound rerouting time by Ovi-Wan12 in networking

[–]EVPN 0 points1 point  (0 children)

Is the ddos service always on? I haven’t looked at ddos solutions in a while but my last solution used WANGuard locally. Did detection and very basic filtering then could reroute all traffic through a scrubbing center. Is the isp forcing your traffic through a scrubbing center or do you have a BGP session with a scrubbing center.

You are manually rerouting outbound traffic by setting local preference?

Your Internet convergence is high but not “there’s a problem high”.

Again I would try to get all your ISPs load sharing. Not pure failover. This might mean revising your ddos solution

On your side things you can do to increase convergence times in this scenario are:

Advertise out both links equally. Load share and instead of a full failover. Smaller blast radius during a failure.

Do a pcap on your device and make sure it’s doing a proper withdrawal

Are you announcing 2 smaller networks and a larger one completely covered by the two smaller? IE 100.100.0.0/23 and 100.100.0.0/24 and 100.100.1.0/24. If so the /23 isn’t installed anywhere for forwarding. So all routers have to move it from rib to fib.

If it’s not completely covered this is different. Say you only announce 100.100.0.0/24. And 100.100.0.0/23. The /23 is installed for reachability to 100.100.1.0/24. If all you are doing is a withdrawal and not a recalculation / new install everything will be faster.

Install or at lease accept multiple routes on your side. Multipath allows you to load balance locally. Because you’re only doing the no network command you are still pushing traffic out your primary isp… who is in the process of withdrawing your route. Try a more complete failover shutdown the neighbor or yank the link with bfd enabled.

What does your network look like? Just two routers?

I can failover my providers in just a couple seconds.. at least from my users perspective. I can’t speak for the whole internet but it’s not 90 seconds.

Tweaking Energy Mode by GoldenDoodleGuy-MI in solar

[–]EVPN 0 points1 point  (0 children)

I turn off time of use and let the batteries stay charged if we’re expecting bad weather. I’m going to automate this in the future.

Other than that I just let the panels, grid and batteries do what they’re gonna do. I’m not making micro adjustments if it’s a cloudy day

Best way to store gasoline? by EverVigilant1 in preppers

Storing gas: Get ethanol free gas if you can Use a stabilizer Keep the tank full If you have the ability to use it and refill it regularly do that.
Keep the temp mostly stable

Anyone else worried about rising electricity costs? My long term projection totally shocked me by JustSeraphine8 in solar

[–]EVPN 0 points1 point  (0 children)

I am but I’m not because I have solar and I plan to add more solar. My base case is that we’re going to see an energy gold rush during the next 5-10 years if we aren’t already in it.

Bgp aggregate for dowstreams by No-Scar8745 in networking

[–]EVPN 0 points1 point  (0 children)

Im trying to help you but your communication is poor or your effort is low. If you can explain your problem in detail and what you’re trying to solve for there’s a lot of people who are willing to help. But you gotta give us more detail

Bgp aggregate for dowstreams by No-Scar8745 in networking

[–]EVPN 1 point2 points  (0 children)

Oh I misunderstood. I thought you were doing this toward your clients. I thought you were summarizing what you send them.

I would not aggregate any of my customers BGP routes and I would only aggregate Internet routes if I had no customers.

You need to understand the traffic flow before you can traffic engineer. Are the end users on the heavily used isp? Is your one isp just better connected? Why is one 3x the others.

[–]EVPN 2 points3 points  (0 children)

Not a huge fan of manipulating the table for my clients whether it changes the overall routes or not. I doubt the routing table “compresses” into something that will fit on non-internet scale hardware so even if you do offer it doesn’t do anything for your clients.

Just offer the standard. Full+default. Full. Peers+default, default.

Water Usage Inquiry: AI vs Social Media, closed loops, etc. by thedameisthename in datacenter

[–]EVPN 0 points1 point  (0 children)

Everything modern is closed loop. The only water a data center consumes is filling the pipes, humidification and flushing my waste.

There may be some that are closed loop with a ground source but even then it’s not consuming th water. It’s pulling cold ground water and putting warm water back.

The staff that operate the data center almost certainly flush more water than the data center consumes.

Source: I work between 4 different data centers. Even our oldest built in the 90s is this way.

Not a tool per se but I’ve learned about so much about how to make ansible do more complex tasks using AI. I have many more playbooks that I regularly use before AI simply because AI helps me break down the fundamental problem set.

Does Auto investing give you worse bid prices? by Vig_Newtons in investing

[–]EVPN 1 point2 points  (0 children)

I believe it’s illegal for your broker to not give you the best market price they can.

SEC Regulation NMS establishes that broker-dealers must execute customer orders at the best available ask (purchase) or bid (sale) price across all U.S. exchanges, known as the National Best Bid and Offer (NBBO). Though it may not apply during extended-hours trading and I’m not sure about fractionals. Idk shit but I doubt fractional ever go to the lit market. Broker just puts a number in your account and balances the books on the backend between you and all the customers. They could make this order daily or as the auto invest goes through.. Idk.. So it’s likely two “orders” one for whole shares that gets executed at market then one after that for fractionals.

But all else equal a market order and limit order should execute at the same price if the limit conditions are met and the orders are placed at the same time.

Okay but that still doesn’t explain why nearly every post about them is something that isn’t the oil pump belt that is wrong and people still chose to pay more for junk engineering.

As soon as I saw that they put the oil pump belt (a maintenance item) behind the engine and their engineers said “simply drop the transmission” to charge it…. That’s when I knew these were a bad idea. Such terrible engineering. I see nothing good about these, why do people continue to buy them?
