There isn’t much to go on here though if DTP requires VTP domains to match so if you had a mismatch your port channel wouldn’t work till you statically set it to trunk...or your port channel was done wrong and your trunk just fixed the problem.

In the future you need to put outputs etc in your post for the discussion to get anywhere

PAGP was Cisco’s first dynamic etherchannel before the standard. Nowadays you’ll most likely use LACP for everything as PAGP only has some obscure benefits in some situations and isn’t supported on servers like LACP is.

You’ll most commonly use a version of PAGP with inter-device stacking (VSS) but that is something you won’t have to think about for quite a while.

What do you think?

I’ve never taken Sunset however my old sales guy went there after the ipexpert explosion, seems decent enough.

RBAC mostly, I can give you access to show commands but config ones based on your privilege.

As for the do command it is more about maintaining structure. Of the main Cisco platforms: IOS-XE, IOS-XR, NXOS, and ASA/FXOS...only the ASA and Nexus support show commands in config without a do command. As you get deeper into command structures when configuring more advanced features you’ll likely appreciate the nesting a bit more.

Replace all your friends and family for Cisco! Then you’ll have time for more Cisco!

Though if you must have non-Cisco relationships you’ll need to find a balance between your goals and date nights etc.

I love this interview question because the candidate can answer as deep as they can. Plus it’s easy to modify to suite the candidate.

Anyway you can go deeper into things like ARP and routing and/or go into things like DNS and NAT.

Don’t use vlan 1!

Original Poster1 point · 3 days ago

That solved my issue!! Is there any specific reason that that would make such a huge problem?

see more

1 is the default native vlan so it isn’t going to be tagged in standard config.

Also for that reason using vlan 1 in the real world is a massive security issue.

BPDU Filter is actually one the most dangerous commands on a switch. Put it on both ends of a trunk and you got a instant loop! Great for labs!

You should know better, it's not an insta-loop. You could but it on every trunk port in an entire large Enterprise network, and assuming no mistakes and mindful design it would work without issue. The problem is you would have no protection, and the only way to do L2 link redundancy would be Port-channels (plus VSS & VPC).

Though I do agree that it probably one of the msot dangerous command, on a switch. But I would put it second after "switchport trunk allow vlan {id}"

Well If you do it everywhere you are effectively disabling STP.

Sure you can do STP free designs but the point was that if you have a redundant link on a switch that isn’t portchanneled it will create a loop.

Cisco gives 6 months advanced notice.

Not always, the DC refresh was pretty much instant and I suspect the security refresh will be too given how people don’t like the current version.

The CCIE is the only exam guaranteed a 6 month update warning and even that has some grey areas with the dot updates.

I thought the CCNA:S exam was OK when I took it last week.

The exam itself is fine, the issue is the out of date OCG and the fact that juniors don’t realize it’s a more senior exam.

But updates are always good!

Do a ? and find out! :)

Once your on the device your on the device, you can even delete all usernames on the router while your connected...just make sure you add them back before you disconnect.

There are no advantages to net+ the cert but if you read through a net+ book you might have an easier time with the CCENT.

The simple answer is you need to master subnetting, there will be direct questions on it and also many other questions will indirectly expect you to know it such as a routing scenario where maybe the issue is actually related to subnetting.

Give the exam topics a read if you want to know whats in the exam :)

SecOps is hard! I got a zero on my first attempt!

Original Poster1 point · 7 days ago

does that mean you got your name wrong?

Even worse! I didn’t show up!

It’s also worth pointing out that Cisco does have other tools for matching IPs that are above the ccna, one of them is prefix-lists which can match IPs based on the prefix length of the mask like so

ip prefix-list MEOWCAT permit 192.168.10.64/25 le 32 which would match your /25 and any smaller mask from that point. Though this feature isn’t directly used for security but route filtering

You could do it but it doesn’t make a ton of sense.

If your a CCENT you are basically opting for the much harder version just in the hopes you get enough CCENT questions to balance out your weak areas.

You would be better off just doing ICND2 since all the topics are worth knowing anyway.

Draw a kitty to keep you company during the exam!

And maybe wherever subnetting aides you would like.

Eh 12 is fine in a pinch for ccna but it is obviously better if you can do 15. However 12 might prove limiting for your lab beyond the ccna, especially since the ccnp is overdue for an update and will have to focus on IOS 15 at minimum and probably IOS(-XE) 16 for the features they will likely add.

Basically there are a number of subtle differences between the versions and some larger ones like IPv6 was rewritten in 15 . Another change off the top of my head is that EIGRP in 15 has no auto by default.

It would actually be “his is” since the “t” would be the delimiter

Yes you can use either network statements (works differently than with IGPs) or redistribution for BGP to learn routes. You can do an aggregate as long a route within the aggregate is in the routing table.

denotes the best route, if there is no < then the router won’t add it to the routing table.

BGP is a massive topic that has heavy presence in 3 CCIE tracks with very little overlap! Issues can range from neighbors not coming up to routes taking the wrong path to more advanced things.

Here are several reasons that could be responsible for the lack of responses:

  • This sounds like a reworded homework question
  • BGP isn't a CCNA topic
  • Your questions amount to " tell me how BGP works". While we are happy to answer any questions, we expect you to do some work yourself

Simple eBGP is indeed on the ccna, though this is far above what you need to know

ICND1 has a lot of building blocks to build the foundations for things like IP addressing.

ICND2 is building upon to do things like routing protocols. So while the book may be shorter (in this case) the topics are somewhat more advanced

Original Poster1 point · 7 days ago

so if you do no ip routing, does a router really serve any purpose at all?

Pretty much...At least for ipv4 traffic
