Step 3: Now we need to enable the sharing of dates and times across the network. You can select a nearby server using the following link: Step 2: In the newly opened window, check the "Enabled" checkbox and insert the IPs of the NTP servers you wish to use. Step 1: Click on the system menu and select NTP client. Then we should make the router broadcast this date and time to other devices on the network.
MULTICAST PACKAGE MIKROTIK UPDATE
First, the router should update its date and time from an internet NTP server. To enable this feature, we must edit 2 configurations.
MULTICAST PACKAGE MIKROTIK HOW TO
Now that you know what the network time protocol is and why it is important to use within a corporate network, let us show you how to configure the NTP on a MikroTik router. Some security mechanisms also depend on consistent timekeeping within a network. For example, certain distributed procedures are dependent upon synchronized computer times with accuracies of even fractions of a second, otherwise, an improper sequence might occur. There are many scenarios where having accurate time across all the computers within a network is important. It is important to note, however, that NTP does not work with time zones, instead, relying on the host to do that. Thanks to it, the accuracy is unbelievably high: down to single milliseconds over a local area network (i.e., LAN) and only tens of milliseconds across the internet. UTC stands for Coordinated Universal Time and is the standard used by NTP to synchronize computer clock time. Thus, special servers (primary time servers) are built to accomplish this task and utilize the network time protocol to synchronize all the devices on the network using UTC. These receivers are not cheap and therefore it very cost-ineffective and inefficient to equip every computer with such a device. In order to connect to an atomic clock, a specialized receiver is needed. Put simply, an NTP server receives the UTC time from atomic clocks and distributes it among different clients. So, how does this relate to an NTP? It synchronizes time across different devices by taking the time signal from one or more atomic clocks and distributing it to networked devices. Thus, the international standard for timekeeping (i.e., the length of one second) is based on an oscillation of a cesium atom. While there are many mechanical clocks out there that can tell time very accurately, nothing can be more precise than an atomic clock. Surprisingly, the term NTP can be applied to both the protocol itself and the client-server applications that are run on computers.įirst and foremost, let us get a little into time precision. NTP stands for the Network Time Protocol and is a protocol that is used for the purposes of clock time synchronization amongst computers within a network. Today, we will show you how to do exactly that.īefore getting to the tutorial, however, let us briefly explain what NTP is and why you should use it within your network. If you are using MikroTik router hardware, it is most efficient to set up an NTP server on the MikroTik router which will automatically update its time using the internet and share it with the other devices connected to the router. In order to reach maximum productivity, you want to have the time on all the machines in your network synced. Was I missing Rendezvous Point setting? (at RP tab)Ĭould please someone let me know how to set up MikroTik router to allow multicast? I see tabs Interface and RP (Rendezvous Points) but I don't know how added records should look like.List of content you will read in this article: In DYI attempt, I set firewall exception (incoming UDP) for VLC Player and "somehow" configured the first tab in PIM module and tried to open list of channels in VLC media player by clicking Network streams (SAP) in left panel.I read router documentation and some forums on multicast topic. I installed PIM package into MikroTik router RB951G-2HnD and checked that it is prepared.In the PC, you need to set an exception in the firewall for VLC media player.
In your case it is fully sufficient if your router supports IGMP / Multicast Filter feature, multicast is broadcasted over port 5004. They provided me with these instructions for enabling receiving of their multicast broadcast:

My internet provider broadcasts several TV channels over multicast on port 5004.
