I actually like the way the IPv6 RFC defines it:
node - a device that implements IPv6.
router - a node that forwards IPv6 packets not explicitly
addressed to itself.
host - any node that is not a router.
So in your list:
"Camera in network",
A router is a node,...
You've got a misconception there:
Does ARP work this way in this case: 1-Host broadcasts an external IP address to the subnet asking who this is, 2- gateway router responds with its MAC, 3- For another external IP the process repeats again and again...
It doesn't work that way. The usual case for hosts is much simpler: it uses its own IP address and ...
I am far from expert in this, however my belief is that the choice of DCF vs PCF is not strictly about ad-hoc vs infrastructure, but that PCF inherently can only work in infrastructure mode as there has to be a coordinator, while DCF could be used ad-hoc or infrastructure; also was the only mandatory method.
DCF and PCF have been superseded by new Hybrid ...
First of all an access port is by definition can only carry one Vlan.
Voice vlan is used, when if its actually a voice vlan traffic needed to be carried.
so lets say both vlans 232 and 233 are Data Vlans.
You have to apply like below.
switchport mode trunk
switchport trunk allowed vlan 232,233
Now , Trunk mode is used carry ...
What is a “routable” IP?
IP addresses can be divided into several categories.
Routable on the public Internet.
Routable on private networks but not on the public Internet
Not routable at all.
People often say "routable" when they mean "publically routable" and "non-routable" when they mean "not publically routable"
The difference is pretty straightforward.
switchport port-security mac-address sticky
Will convert all dynamically learned MAC addresses to sticky MAC addresses so that you don't have to statically define them (like if you had a couple hundred hosts).
switchport port-security mac-address sticky ae11.be22.ce33
Simply allows you to ensure that one is added ...
The way I have seen it used (and try to enforce myself to more effectively communicate) is that a host is any device that is an endpoint for communication, like a PC, storage, printer, etc. Node, like the wikipedia article suggests, is a more general term for any defineable point on the network where information might start, sit, or change directions; so ...
MPLS support is only rarely a requirement for enterprise equipment, especially relatively simple setups like the one you describe. MPLS itself is usually hidden away in the carrier networks. For your situation you basically you have two options :
you can ask a network carrier to provide a private VPN service, which will typically be MPLS based. In much of ...
The term "local loop" comes from analog telephony. It is also called the "last mile." The definition is not precise, and certainly things like "access medium" were never imagined when the term was created. In other words, there is no definitive answer to your question.
The physical connection to the subscriber is usually owned by a particular service ...
You need to set up 802.1X, that way you can guarantee that users are strongly authenticated before accessing the company Wifi. Use RADIUS or if it's a small network you can get by with the built-in authentication methods that are available in most enterprise grade Wifi-controllers. Also look into limiting access for the Wifi network only to resources that ...
According to the documentation for Configuring Cisco StackWise Virtual
The SVL link needs to be connected to the sup-module.
StackWise Virtual Link (SVL) connections are established only through 10G or 40G uplink ports on the
supervisor module. You cannot establish an SVL using a 10G port on one switch and a 40G port on the
Please refer to ...
Your thinking around the external BGP advertisements is sound, although as other have suggested, I'd highly recommend you run BGP with your providers for automated route-withdrawal on failure. Consider also the need to take a site offline for maintenance, or the need to add, move or migrate providers in the future.
Having said that, how about an ...
I think the short answer is that usage varies and is really a matter of emphasis.
RFC 1122 Requirements for internet hosts says "A host computer, or simply "host," is the ultimate consumer of communication services. A host generally executes application programs on behalf of user(s), employing network and/or Internet communication services in support of ...
The easiest rule is to go by how much network stack is implemented.
A node is any device that is "active" in the network (=has a network port and is more than an electrical adapter); a node may have only a partial network stack, e.g. only physical layer or only physical to network layer.
A host has a complete network stack from physical to application ...
This function is called "Captive Portal".
It basically works in the following way:
New user connects to AP
All traffic of this user (identified by IP or MAC) is redirected to the portal server and access to anything else is blocked by a packet filter firewall
After registration/successful login, a dedicated "ALLOW" - Rule is created for the user, allowing ...
There are many wireless companies, many of which I have no experience. That said, I personally have never seen or heard of any Pakedge or Luxel wireless deployments.
There has been a lot of change in this industry and probably will continue to be. If someone were to ask me a list of vendors to consider, this would be my current list (in order):
A /32 mask is often referred to as a host address, and it means a subnet with a single host. That is normal IP addressing and it works in ACLs or routing or anywhere else you use IP addresses.
One thing to mention: For Cisco IOS, ACLs are written with a "wildcard" mask, which is the one's complement of the subnet mask. So 255.255.255.0 would be written ...
Your question is lacking quite a bit of detail before a specific answer can be crafted. A diagram of your current equipment setup would help.
Given your question is about how basic routing works and you mention both locations have WiFi, i am going to assume that your network consists of 2 wireless routers, both are performing NAT.
I have tried to minimize ...
There's a standard to achieve this: 802.1X.
Basically the switch request authentication from the computer, then contact an authentication server to validate the credentials and depending on the answer the switch will deny or allow access.
There's further possible options, like placing the host in a guest vlan if not authenticated or placing the host in a ...
when we are dealing with local loop we indicate the last mile of connection from the CABINET (or whatever else) to the subscriber.
At least in the UK it's the line from the telephone exchange to the subscriber, not merely the line from the cabinet.
Or is the opposite, where multiple carriers borrow the last mile wired part and then they have their own ...
If your ISP routes packets but you have a dynamic IP address, perhaps all you need is any one of the dynamic DNS services, whereby your systems register the current address.
If the incoming packets aren't delivered because of the ISP's policies or its NAT configuration, you might care to search for "vpn services static ip address", and you'll find many ...
In short, you can't.
One option is to create a separate WLAN (with a separate SSID) that has a static password. You should also apply strong filtering on that WLAN, so that the devices can reach only the necessary destinations.
As @ronmaupin points out, IoT devices tend to have all sorts of vulnerabilities. So putting them on a general production WLAN ...
The issue is where/what you're tracking. You need to be able to continue to steer traffic over the down route in order to tell when it comes back up. Using PBR for traffic sourced from the router (ip local policy) will do this.
We don't need to track the backup (the floating static route with AD 10), because once the track object for your primary route ...
3D Universal Edge Routers is Juniper Network's Series Product name. you can find more info in there.
3D means a physical, you can touch's product, it contrast to virtual product.
Universal means its usage vast, not limit to Juniper product, it can also join up to Cisco, Huawei and so on network products.
Edge means the Internet's edge. if you know ...
A radio access network (RAN) is part of a mobile telecommunication system. It implements a radio access technology. Conceptually, it resides between a device such as a mobile phone, a computer, or any remotely controlled machine and provides connection with its core network (CN). Depending on the standard, mobile phones and other wireless connected devices ...
You can place an extended ACL where you want (as long as it is in the path of the packet you want to filter of course). However, depending on the filtering parameters, it is usually better to put it close to the source. This way, undesirable traffic is denied close to the source network without crossing the network infrastructure, which limit bandwidth usage....
A network node has an OSI layer 1 network hardware interface with a hard-coded OSI layer 2 physical address. This hardware address type is for data transmissions which are recognized only within its own network segment and are not routable by themselves.
A network host, is also a node, but has an additional OSI layer 3 logical address as well. This logical ...
In my understanding, a host is an end system/device, which can host /run applications. A host could be a Client or a Server. The type of application differs in both these cases.
The nodes will not know much about the applications.
In your question, router and switch are nodes, while a camera and printer can be considered as hosts.
