Iโve seen a lot of posts recently of people having syncing and relay issues- long wait times. Iโve also been sitting in sync for 2 days on one miner and am still waiting for my other one to get off relay (3days) after port forwarding. Iโm just curious if anyone is also experiencing long/quick wait times, or if itโs time to start trouble shooting. Iโm assuming the blockchain is v congested but Iโd like to hear how others are fairing
To anyone who has completed the CCNA exam recently, do they still have old topics like RIP, frame relay, crossover/straight thru cables etc in there?
This seems like it would be hilarious hmu if you down lmao
Looking through the exam blueprints, I couldn't find anything on it, but a co-worker of mine who has taken the exam swears there was one or two questions on it. Has anyone ever came across any questions on it?
I just go started learning about networking, and I am reading up on WAN technologies. For some reason I cannot understand why MPLS is more efficient than Frame Relay. From what I understand, Frame Relay can send frames to its next hop based on a DLCI located on the header. MPLS seems to do the same thing but with labels yet I have read that it is faster than frame relay. What is the difference and advantages of using labels vs DLCIs?
I trust you are all well community. I am preparing for my Network + exam and i am really struggling to understand what a frame relay what it is and what it really does. I have watched youtube videos and but i still could not understand. Can someone please explain it to me like as if i am totally beginner. Meaning in very very simple term.
So I get that it creates the PVCs and all that. But can't we do basically the same thing with all routers? For example. if you have this setup.....
http://4.bp.blogspot.com/-wiwDKZhiHbM/VOynJDnTKxI/AAAAAAAAAEs/66DwMvlBBZY/s1600/fullmesh.jpg
Couldn't you just use another router in the middle instead of the frame relay switch? And then just create gre tunnels (or ipsec gre tunnels) to create basically the same thing as the PVCs? Or am I way off?
I originally thought that frame relay was for transporting L2 frames over a WAN setup, but I think I am wrong there, or am I not?
I have looked as the tshoot exam topics and it does not specify frame relay troubleshoot. I am taking that exam instead of route or switch and then let is convert to the encore. I think i can get ready for it by feb23 but they took frame relay out of the ccna route/switch so should i bother learning it.
Hey, I'm trying to do some last minute studying for Frame Relay as I prepare to sit my Route exam next week. I'm having some confusion over how to get spoke-to-spoke communication working in a P2MP Frame Relay setup.
In my head, I should just need to disable Split Horizon on the Hub router's s0/0 interface so that routes learned from one spoke will be propagated to the other spokes, while still leaving the next-hop-self setting enabled in the Hub so that the spokes know to send traffic to the Hub to reach the spokes.
But that doesn't seam to be the case, as no matter how many times I enter no split-horizon on s0/0 it never seems to stick in the config. I'm still not learning routes between the spokes. Can someone tell me what I'm missing here?

I work for an ISP, and I don't think in my 7 years I've had the experience of working with a customer that was cutting over from Frame Relay to Ethernet.
If I were to put together an example lab, would there be any benefit to adding Frame Relay aside from understanding the manner in which it communicates and how dynamic routing protocols would function using it?
Dumb question, but I had set up a frame relay switch with mapping 1:102 2:201 1:103 3:301 R1 at 1, R2 at 2 and R3 at 3 of FRS.
Why can I not ping between the spokes R2 and R3? Even after adding 2:203 3:302 to FRS All interfaces are at same subnet
I've seen a few complaints in the past about the CCNP ROUTE exam including Frame Relay in the exam topics, even though it was removed in the latest update to ICND1, ICND2, and the CCNA R&S composite exams. This has created a bit of a knowledge gap for people who recently obtained their CCNA and are now pursuing their CCNP, as Frame Relay is a topic where Cisco expects you to have obtained basic knowledge about the technology from your CCNA.
Fear not! Today we'll take a deep dive into Frame Relay. We'll cover how it works, its purpose, what problems it solved, how it can be configured, and how routing protocols need to be configured in order to work over Frame Relay. As a shameless self-plug, I posted a prettier version of all this on my blog as well - feel free to check it out if you'd like to!
#Overview - The What & The Why
Frame Relay is a wide-area network, industry-standard data link layer protocol jointly created by a number of companies in the early 1990's as a replacement for the X.25 WAN protocol. Frame Relay superseded X.25 thanks to its simplicity; it relinquished resource-intensive error correction algorithms in favor of the simpler CRC (cyclic redundancy check) algorithm, allowing for higher performance and greater efficiency. It also lacks explicit flow control procedures, which were made redundant when protocols further up the OSI model implemented similar technologies that were more accurate and efficient; Frame Relay opts for simpler congestion notifications, commonly known as FECN and BECN (which we will discuss later!)
Frame Relay is also a packet-switched WAN technology, which means the service provider's network is being utilized by multiple customers simultaneously. This lies in stark contrast to traditional circuit-switched WAN technologies such as a leased line, which is a true point-to-point connection between two sites that is not shared by any other customer. The advantage of a packet-switched WAN technology is cost; leased lines tend to be extremely expensive for both the service provider and the end customer. This is primarily because the service provider has to dedicate bandwidth within their infrastructure to you, while with packet-switched WAN technologies, the network is shared between multiple customers at the same time. Since the network is shared, this means that if a few customers are fully utilizing their connections to the service provider,
... keep reading on reddit โกAs the title says, this frame relay video (by Kevin Wallace, no less) has been really helpful to me in place of me trying to piece together my memory of Frame-Relay from CCNA when I took it 6 years ago (and haven't seen it since! lol when do they rewrite this test?). All of the CCNP materials talk about Frame Relay like you know it already, so this really put all the pieces back together. Everything else you need to know should be in the OCG and Bryant stuff.
What has been a resource you found that has been helpful in your studies?
Edit: So wound up I forgot to post the actual link for the video...ugh. Anyways, here it is.

P.S. - I sit for the ROUTE exam tomorrow morning, wish me luck!
Hi all, I'm currently studying to take 200-125 next Thu* and had some questions about the practice exams I'm finding online. Many of them have frame-relay question and hub questions that weren't covered at ALL in the Cisco course I took through school. That course used the Netacad coursework which I thought was current, as it stated something about frame-relay not being used anymore.
Does the current 200-125 have questions on those topics? Also, are the Boson practice exams updated, as they seem to be from 2015 maybe? I'm trying to decide whether to drop the money for them. Thanks!
*Completing the netacad course with good grades gives you a discount voucher. BUT you can only apply for EITHER a 200-125, or a ICDN2 with it. Me being a moron, clicked without thinking, and ended up with that one and an ICDN1 discount. SO I have the ICDN1 as a backup if I fail the composite. Learn from my mistake!
"Hey, where the hell is my FECN BECN??!"
I'll be here all week!!!
Edit: I was asked to leave immediately
I've recently started playing again because I made a new group of friends, and they play warframe quite a lot! But unfortunately, the last time I played it regularly, excluding the past two days, was back in 2015-2016-ish. When I logged off back then and put the game down, I was on console. I've since picked it back up on PC since nobody else I know plays consoles anymore. My issue is, I'm lost. I'm running through the beginning missions once more, which is no biggy. But my friends are referencing weapons, gear, frames, components, and lore that I've never heard of. And I have no idea what's going on. I love what's been done with the game, and it's nice to see that the community is as fantastic as it was back then, maybe better! But I'm so lost and confused. The lore I can pick my way through on my own, but game mechanics are gonna be the death of me. Any advice or tips... Or hand holding, is VERY welcomed. Thanks!

Hello Reddit
I have finished reading OCG for ROUTE by Kevin Wallace and found that there were nothing about exam topics like NetFlow, PPPoE and Frame Relay (just a few words about EIGRP/OSPF over WANs)
SO I wondered - how deep should I read and practice FR for exam?
I have a bit of knowledge about PVC/SVC, DLCI, LMI, DTE/DCE/NNI interfaces, static mapping and InARP. Plus some knowledge about topology types like point-to-multipoint and point-to-point using subinterfaces.
Should I know more technical depths like FECN, BECN, Discard Eligibility, or differencies between LMI standarts (cisco/ansi/itu)
thanks in advance
cheers
Do they still ask about it in the new version? I was told they dropped it from CCNA but it's still important concept and should be learnt..

Can I set a single physical interface on a router, into the frame cloud that can reach all the other routers connected to it?
How best can I simulate that in GNS3?
