I've been working on a series of lessons on networking for my upcoming AWS SA pro course. BGP supports a lot of AWS tech such as Direct Connect, Dynamic Site-to-Site VPNs and other hybrid networking. I'm aiming that my SA Pro course is doable by someone directly from the associate SA and so im including some deeper core lessons on things like BGP, DNS and IPv6 to help the skills jump between associate and professional.
Anyway ... i thought I'd make the lesson free because so if it helps anyone using other content to understand some of the more complex AWS networking - awesome :)

A student suggested i post this on reddit .. as it helped him understand BGP as a non-networking person.

I was reading this article, and I did the test (here) with both PVPN on and off, and in both cases the final score was "Failure".
Should /u/protonvpn try to push this issue forward with their "partners" (companies from whom they rent the servers)?
What do you think on the matter?
How is weight decided on BGP? The cost? Hop count?
AS the world moves into the 5G era, BGP is playing a significant role in the networking. Although BGP is popular in This industry, it ‘s difficult to understand. SPOTO involves a further area in the IT industry, which will provide various and influential certification such as CCIE, CCNA, CCNP, AWS,CISSP, to assist you to march into the IT industry. SPOTO is a stepping stone to understand BGP.
BGP is an external gateway protocol for communication between routers of different autonomous systems. BGP is a replacement for the old EGP used by ARPANET. RFC 1267 [Lougheed and Rekhter 1991] describes the third edition of BGP.
I know this is the routing protocol that is used on the internet. Everyone keeps telling me it's super complicated and advanced. Could anyone explain it in simple terms for me? For example, how does it differ from interior gateway protocols? Why is it effective for the internet?
On iOS, using the app "Discovery DNS SD Browser" you can examine the use of Bonjour services on your network. Tradfri shows some odd (?) behavior. In the app, click "_hap._tcp", and my list looks like this:
HASS Bridge N2EQ
Homebridge Name
TRADFRI gateway
TRADFRI gateway-1
TRADFRI gateway-2
....
TRADFRI gateway-255
AS you can se, compared to Homeassistant and Homebridge, Tradfri gateway creates 256 instances, and it loops through which instance is active, meaning that if you click them it s just "resolving". Compared to clicking for example "Homebridge" where is shows detailed information. The TRADFRI instances sort of rotates which entry is the active one
What I hava noticed is that if I disconnect my Apple TV, reboot my router (ASUS Zenwifi XT8), reboot TRADFRI, then check with the discovery app, you can se that it starts with just one instance of "TRADFRI gateway" in the _hap._tcp list. When Apple TV is connected, the looping of instances start. <-- This is something others can test as well.
My observations when HomeKit is "Not Responding": Tradfri app itself works. Homebridge works.
That the entries for TRADFRI loops looks like it could cause issues like "not responding" since HomeKit gets constant updates on the entries. This can probably differ on how well the router handles it.
EDIT:
My conclusion after some tests is that this is an Avahi issue, not Tradfri. If you have Linux machines on your network, they may have Avahi installed. It hink has an impact on how well tradfri works.
Check your Avahi version using avahi-daemon --version
If not at 0.8 (latest), try to update. There is a bug in earlier versions of Avahi that cause the issue observed, I did this on my raspberry pi's, updated raspbian from buster to bullseye release that has Avahi 0.8.
Result: No multiple TRADFRI Gateway when checking with the Discovery app. None of my apple devices renamed themselves. And HomeKit and the Tradfri App feels more responsive. No "no response" so far.
I am looking at alternatives to Anchor Protocol to generate some extra yield without losing any of my principle UST. I have not really paid much attention to Pylon Gateway, but I have noticed that many of these launchpad events have a higher APY. There was news earlier that White Whale will have a launch on Pylon with the option to claim rewards starting as early as one month after vesting. However I am not sure if this is ultimately worth it since my principle would be locked up for half a year, and it is not guaranteed that the price of the token I am farming wouldnt dump during that period of time. I have noticed that these NFT launchpads have shorter lock up periods but that seems like more of a random draw based on how much I am staking. Any advice?
This deserves a real non-meme discussion.
In a non-pandemic year, we used to fly Ebola patients across national borders for treatment and study. He is a US citizen and from what I understand, he has to quarantine 14 days (and show negative) before he can come back.
It's not that I really care about the Clippers or Ty Lue, but this situation is a precedent for a playoff nightmare.
Basically, unless the Raptors are willing to come back to Orlando and make it a home-away-from-home, during the playoffs what will happen if one of Raps players tests positive here in the US but can't cross the border for the home game? It's not the 5 day protocol (for vaxxed players) that the NBA has, but rather the 14 day that is law that makes this situation extra spicy.
