Greetings, I have a doubt. I know that there is a gns3 client that is installed in the operating system.

but i see there is a gns3 for vm

that gns3 for VM In a few words it is a virtual software to use it with a hypervisor

It's a bit confusing, I can't understand

thanks

Difference between vpn protocols and tunneling protocols

You can see the question easy but not on google i find it

i note that they always mention 5 protocols

PPP, L2tp open vpn and others

but then i observe that they mention the word tunnel

and i see there is ipsec, Gre, dmvpn, flex vpn. ikev2 and how do i get confused

and also i see that it says l2tp uses ipsec it is very confusing all this issue

i am a student

I want to remove this network from SWITCH L3

THE PORT IS NO LONGER ROUTED AND I DON'T UNDERSTAND WHY IT DOESN'T WANT TO DELETE

AND IF I TURN OFF OTHER VLANS

I DO NOT UNDERSTAND WHAT HAPPENS

Hi Luis,

Please check how ACLs are configured and then applied in your case? For a single router, you will have two ingress and two egress locations:

-----(A) router(B)--------

Above diagram shows interface A and interface B only. Traffic can come "in" via interface A or interface B. Same for the reverse, which is the egress.

I'm not sure where those IPs or subnets are located but to make an ACL work you need to apply it to an interface and in a certain direction.  Such as "ip access-group PRACTICE in" or "ip access-group PRACTICE out".



2nd, I'd also place the deny statement at the top. So delete line number 30 and then re-create it at a line number above "10". For example:

Code Select Expand


conf t
ip access-list extended PRACTICE
no 30
9 deny ip 192.168.3.0 0.0.0.255 192.168.2.0 0.0.0.255

Then if you want you can renumber the lines so that they increment in 10's again if you wish (like line 10, line 20, line 30)

Code Select Expand

ip access-list resequence PRACTICE 10 10

sorry to changing the position of the acl as you mentioned the problem was solved

l would like to know why the order i had did not work

when the two options was allowed
and the last choice was to deny

because i thought that if i put deny as a second it would not work for me, permit third party

can you explain to me the why of all that please

l am a student and i don't want to leave empties in my mind

greetings to all members of the community

I have several days with this lab and I can't do it correctly

I am a student of networks

THE EXERCISE IS THE ONE WHICH IS GREEN
I have an EXTENDED ACL and two subinterfaces

the requirement is

192.168.3.0 can access the server

192.168.3.0 can access 192.168.1.0

and the negation is that 192.168.3.0

cannot access the 192.168.2.0 network

but it happens that
the 192.168.3.0 network is accessing the 192.168.2.0

when in the ACL I AM DENYING IT

if someone can help me please

and tell me why this problem is happening

Router # sh access-lists
Extended IP access list PRACTICE

10 permit ip 192.168.3.0 0.0.0.255 192.168.1.0 0.0.0.255
    20 permit tcp 192.168.3.0 0.0.0.255 host 172.19.10.2 eq www
    30 deny ip 192.168.3.0 0.0.0.255 192.168.2.0 0.0.0.255

THE EXERCISE IS THE ONE WHICH IS GREEN

I have a question, it may be stupid

but I have that doubt

I have an ethernet card for fiber optics, if my ethernet card is 1 gb / s I think that is the bandwidth of the interface

and my fiber optic is 10 gb / s that is, my cable

How would the traffic be for the 10gbps or only 1 gb of bandwidth of the interface passes

hello I would like to have your understanding on this problem solving
I don't speak much English but I'll try to explain

I have two subnets here and two vlan that happens I know very well the STP ptotocolo but I observe that there are no loops and I have redudancia in the network and I see this and I say and because there is a blocked port

data I have the interfaces in trunk and native mode because the one that is not colored is a vlan 99 for native traffic
then what would be the cause of this problem that there are no loops

in very few countries ipv6 is implemented

Which Is The Objective Of The Ports Designated In Stp If The Root Port Sends Bddu Also This Has Me Very Confunsed I Look And Search On Internet And I Do Not Find That Doubt ??

GOOD I WAS READING THAT ONLY IN GERMANY IS IPV6 IMPLEMENTING AS A 25%

but later in Latin American countries 0.5% United States 14%
