Have you bothered to search or research.

These "sky is falling we'll all be working at McDonalds when we're replaced with python" threads are occurring every couple of days or more.

Even better irony when one of them is yours:

Damn I completely forgot about this. Whats with the animosity, I was just asking a question to gather inputs back to my co-worker. Then again I could see how this would annoy yall

The frustration is that no one bothers to search, and we're continually removing the same old "devops, cloud and automation are going to put us all out on the streets" rhetoric.

arming10 1 point

Agreed but to say this is a low quality post is just BM. I literally gave examples, did you bother to read or did you just assume because of the title? While I mean no disrespect I am in no regards someone to take BM from anyone. You can remove the post, but you are fucking fooling yourself if you think this is a low quality post.

I was typing out exactly this, then I scrolled down and found the answer.

To better word what /u/GodOffal said: you wouldn't send traffic down a trunk that has no purpose going across that trunk. It is poor design due to extra traffic that doesn't need to exist, more computes and a slew of other reasons. Basically GodOffal said it all.

Second question: GodOffal nailed it perfectly.

Is this a question of the day for each day you were missing? Goddamn, that's chock full of questions!

1) What are the key difference : one is super old and shitty, the other one slightly less so.

2) Which one is classless and which one is classful : RIPv1 classful, RIPv2 classless (sorta).

3) What does that means in prod : well, unless you are running a network straight from the 80s (looking at you, every single hospital on this continent), you probably have subnets that aren't 100% classful, so go for RIPv2 if you must.

4) What's the difference in communication : they shout loudly to whomever want to hear. RIPv2 can also shout loudly to specific neighbors.

5) Loop prevention : hop count.

6) Route poisoining : when I see a route go away, I yell loudly "this one is dead!" to be sure my neighbor is not going to yell at me he can reach it only to discover he could via me. (Routers are dumbasses)

7) Split horizon and NBMA : It tends to break things if you got a point to multipoint setup.

8) RIP over FR/DMVPN : Yes, it can cause issue. You should be aware of these issues and configure it properly. If you want to do some 3rd party DMVPN, you should use BGP or RIP, since you can't use the recommended EIGRP and since running OSPF on DMVPN is asking for a world of hurt.

RIP RIP.

WHAT, DAS RACIS BRO!

It's going well, I'm all moved into my new place, and I'm currently shopping for a new car.

I also will post an OpenStack lab/tutorial soon, now that I got a shit ton of new toys in my work lab (3x R620, 3x X8DTU-6TF+, 2x Edgeswitch 24).

Glad to see you again!

arming10 1 point

You too man! I am about to finish up NP Switch and maybe continue with my NP Route after, but the NP exams are about to be updated soon, so I may hit DC real fast since I touch Nexus a lot.

How's life bro? I am glad that everything is going good and hope it continues :) <3 (No homo)

After a bit of testing show ip protocols will show it routing 192.168.0.0 but if you look in the routing table of the router on the other side it should show both 192.168.1.0 /30 and 192.168.1.8 /30 as separate networks.

arming10 1 point

Can you show me your network statements bro under the RIP router config?

FantaFriday 1 point

It will only save the classfull network notations. So basically if you type network 192.168.1.0 it will put 192.168.0.0 in your configuration and enable it for 192.168.1.0, 192.168.2.0 and 192.168.3.0 etc.

arming10 1 point

Ehh not 100 percent true! Classful means that if I put in a network of 172.16.0.0 it will assume and dictate that it's subnet mask is a /16 hence why classful networks are not a thing anymore and CIDR was created. What you are talking about is auto-summerization.

I am sure my mans /u/the-packet-thrower can comment on this as well!

Edit: Thought this was an answer for my question of the day lol. Can you post your network config and topology? please and Ill help :) I know RIP pretty well. Also, I assume you are running RIPv2 right :)

Absolute bullshit. I feel bad for you man. As soon as you find another job give them your 2 weeks and GTFO. Your CIO/CFO got me fucked up if that was me I would tell them they need to pay for my insurance as well as my phone to call me or to have me drive somewhere 3 hours away. Do not let them take advantage of you, remember that IT is a business and business is a game. Whoever plays it better wins..

"2 vlans out of the 20 other ones you provisioned aren't working. You've done troubleshooting on your side, but because my ucs never makes mistakes it must be something wrong on your network switch and I refuse to check into my fabric interconnects for issues.

No - I was hoping to not have to neighbor everything with everything.

But from what I am hearing I have to do that, or do a route reflector...

Makes iBGP less appealing for my setup, I suppose.

arming10 1 point

Yeah iBGP can be a headache when you have tons of routers. Also, don't set up just one route reflector set up 2! Allows for redundancy and load balancing in a way. Also, it solves this issue you are having now where you have to peer all your routers up with each other :)

Acrylicus 1 point

Thanks for the help - I am going to go ahead and set up PE2 as a route reflector :)

arming10 1 point

Good luck bro! Let me know if you need help bud. :) Now back to NP switch videos

A certain source tells me that you don't like Henny and that you didn't take a shot for that said source. Is that true):

the-packet-thrower 2 points

Your source is wrong, the conversation was that the town I was in didn't have anything as fancy as Henny. Though I'll have a drink of cognac now in interest of peace.

upvoted for your support of henny

The VP of Technology for my current company, who controls all technology decisions - doesn't trust VRFs.

He would rather and does purchase double the equipment.

WHAT. UGH I feel bad for you brah. VRFs segment routing tables and offer isolation among other things. UGH feelsbadman

Yes, my previous gig used VRFs extensively. :(

Are you in an enterprise or SP environment?

Answer to you question bud: What are the actual differences between a high end Cisco style router, and a little home router you get sent to you when you buy a package from an ISP? A LOT. Your little piece of shit router/modem may not be able to do routing protocols, VPNs, QOS, etc. The difference is the features each provides. You would never see anyone in a large Enterprise environment use a router/modem like you get from comcast, etc. The reason for this is because those are home routers. Other router's like the ASR 1001 can do routing protocols, VPNs, MPLS, etc. I mean, fundamentally they both obviously do the same thing, they route packets out to the internet, but I'm looking for specifics... Physical/virtual differences? Clarify more on this question. Usage scenarios? I could go on and on about design need to be more specific. Do the high end routers support wifi, or do you need a seperate access point? Typically high-end routes used in the SP/Corporate environment do one thing and that is route. You would never want you router to do everything in these environments (you wouldnt want it to be a router, AP, etc). You want to spread that out by buying a WLC, APs, etc because of the stress it can have on the router's hardware.

DrParallax 1 point

Also, performance matters a great deal. Just because they are both gigabit routers, doesn't mean that the home router can handle 1000 clients and a constant stream of gigabit traffic across its interfaces. Memory, CPU and other specs will be vastly different.

arming10 1 point

Again, I was not trying to get into specifics. Just gave a pretty boring answer haha, but yes you are correct as well mate.

Thanks, sounds good to me, I'll probably pick it up. Might get that NX-OS book too.

arming10 1 point

I recommend both but if budget can't afford both get volume 2. So so so so good! Especially for learning about VSMs, VEMs, and the specific product lines (The OCGS go into each type of nexus product in depth so thats nice and better than the old books).

Viginti 1 point

I checked out the Cisco Press site and the search didn't have anything called Cisco Nexus Switching Volume 1 or 2. Same with anything NX-OS.

Could you drop a link to those please?

Yes, that was my question. Since they aren't in area 0, they need to be in 104, if not you'd need a virtual link to area 0.

DC is one of the more senior tracks you really shouldn't think about it until your working and are at least on your way to CCNP R&S. Plus it is being updated next month so it had to say if it will become easier or harder.

arming10 1 point

True, I am only doing the NA DC because I deal with UCS/Nexus and I maintain our 3 DCs infrastructures and backbones.

If marijuana were legalized in my state I would purchase a small plot of land and fill it with greenhouses. Bye bye IT. However, I did just recently move into a CRM position so I am no longer doing any actual technical work.

If it ever does get legalized in your state let me know and I would gladly help. Michigan OP

I would not be using used equipment for your CORE...We are talking about the section of the network that runs everything/that everything passes through.. This is a no/no. If you are willing to take a risk and be foolish go ahead and do it, but I am telling you right now it can go either really good or bad.

tt_2014 4 points

I agree that a problem would be a major issue, however we've had hardware issues with brand new, as well as multiple software issues which would afflict us in either case.

The question is - actually how much more likely is an issue with 2nd hand hardware?

If I bought it new, and 2 years later moved it to another location - is this any different to buying someone else's? Only real difference is you don't know what "life it's had"....

Empirical/non circumstantial data would be a huge help here :)

arming10 1 point

To be honest if it was for any other part of the network I would say go for it. But we are talking about your core here man...

The only thing that I know about this is that the connection between the company and the ISP is known as a dual-homed connection.

That counts for something! :D That is a design term too btw! GJ BRO
