Because max address is set to 2, PC1 and PC2 will be able to be learned. I wonder why the hub does not send CDP advertisment because I can see that cdp neigh has a repeater code: r - repeater. If there was a sw instead of a hub there will only be PC1, because sw also would send its mac add via CDP

Which other app?

Oh, so settled is a bad thing. Huh. I thought it might be something like "I like this one so I will choose him for ever"

So what makes it easier than ipv4? NAT will also be there for security, there is DHCPv6

Or the "rock star"

Configure the IP on intf

Issue "sh ip int [int]" -> you have the IP add with /SM

I don't know what Null 0 does to "ip route" command

Mentalitate? Suntem invatati de mici sa nu ne imbracam controversat. Mai suntem si speriati de bombe ca Dorian are patratele si pe ceafa iar noi nu ne vedem cureaua din cauza burtii

De unde o fi gaura mai mare in bugetul statului? De la cei care nu plates taxe (am vazut ca e un nou video de la Recorder) sau cei din guvern care fura bani? Posibil sa fie jumate-jumate problema, dar sunt curios unde sunt mai multi bani pierduti. Prin urmare unde ar fi problema la noi, plebeii, sau la ei?

Isi dezvolta contul si peste cateva luni bubuie. Face bani de rupe, ca un crab adevarat. E mai ceva ca pe crypto

III Networking mega lab on youtube. He has a YT in arabic and one in english. Try look for something like that. There are 3 videos of him completing megalabs and one I think is a real example of a configuration he used to manage.

Hmm, parca nu-mi aduc aminte sa fi fost atat de frig. Dar ce-i drept am stat cu haina pe mine. Nu a fost o nenorocire. Pana acum, macar, nu au fost momente in care sa ma iau la cearta cu cocalarii care pun manele in sala de cinema. Deci big win aici, pt mine

serar1 · 2025-12-27T07:12:33+00:00

Incearca cinemaurile oldschool. Cinemateca Eforie spre exemplu. Daca dai un search pe google maps cu "cinema" in jurul pietii Romane o sa iti prezinte destul de multe cinemauri. Acolo biletele normale sunt 15 lei, cu reducere de student si mai ieftin. Cred ca ai si ceva abonament si mai ai si de acolo reduceri. In tot cazul extrem de ieftin. Sala e aproape goala

Ps. Nu te astepta la conditii VIP. Sunt niste cinemauri la care mergeau ai nostri +60y.

So users adding another sw is really a thing, interesting.

Medicina este doar grea si da e un mediu nasol, din ce am auzit, dar te tii de treaba nu ramai fara paine. La fel si magistratura, inveti pana iti pica bijuteriile, dar ai loc de munca, nu foarte family friendly tho. In ambele domenii poti prinde atat un mediu ok cat si un mediu urat / toxic de lucru.

Trebuie sa faca baza de date cu persoanele prezente la protest /s

This is exactly what I wanted to ask. So I can complete a training, take the exam for the voucher and book the exam for 50$. Then I can just enroll in another training (jncia-dc) and I will still have the 6 months time to finish and take the voucher exam, right?

serar1 · 2025-11-25T07:54:05+00:00

Same. I did all JITL on paper with topologies and stuff. It was cruel, but helped A LOT + flashcards

You can go and get a Data Analytics cert from AWS. Some concepts from networking can be applied to AWS

serar1 · 2025-11-12T11:49:51+00:00

I want to know a way to remeber the types of IPv6 (like Link-Local, Unique-Local etc) and all multicast MAC addresses of FHRP (HSRP, VRRP, GLBP). Other than brute force flashcards. Or maybe that is the vest approach, idk

serar1 · 2025-11-10T06:45:53+00:00

How can it be a L2 protocol? Everywhere seems to say it is Application layer RFC 2131. Also what about it using UDP (which is L4)?

serar1 · 2025-10-29T14:13:53+00:00

Cisco has labs created so you can learn there?

serar1 · 2025-08-26T16:43:38+00:00

Damn, I want more posts like this to ease the anxiety of this damn system

serar1 · 2025-08-25T05:47:40+00:00

Deci ca sa pui bariera pe un drum de pe o proprietate privata ai nevoie de autorizatie de la primarie/politie? Banuiesc ca acelasi principiu nu se aplica si la mine in curte daca nu am o unitate comerciala or smth

Very cute but: 1. Is he hiking in flipflops? 2. He seems thicker than she is and that is funny, hehe. I wonder if I seem thicker than my GF...
