This is due to (R)STP, this type of configuration forces the device to send out tagged BPDUs, that might not be supported by other devices, including RouterOS. Please, consult the respective manual on how to set up a L2TP client with the software you are using. In this case, both endpoints can be any type of device, we will assume that they are both Linux servers that are supposed to transfer a large amount of data. IP-in-IP tunnel Scenario Cisco-1841 MikroTik-hAP LAN-Address: Fa0/0 : 192.168.1.1/24 Fa0/1 LAN-Address: Ether1: 192.168.2.1/24 Public IP: 100.1.2.2/30 Public IP . Layer 2 VPN is not supported on the EX9200 Virtual Chassis. This can be done by creating a VLAN interface on top of the bridge interface and by creating a separate bridge that contains this newly created VLAN interface and an interface, which is supposed to add a VLAN tag to all received traffic. Client needs secure connection to the office with public address 1.1.1.1, but server does not know what will be the source address from which client connects. Below you can find an example of how the same traffic tagging effect can be achieved with a bridge VLAN filtering configuration: A very similar case toVLAN on a bridge in a bridge, consider the following scenario, you have a couple of switches in your network and you are using VLANs to isolate certain Layer2 domains and connect these switches to a router that assigns addresses and routes the traffic to the world. It might be useful to define a large number of VLANs using a single configuration line, but extra caution should be taken when access ports are configured. On that one you need to type: add mac-address=FE:BF:F9:12:DA:89 name=eoip2 remote-address=WAN_IP_OF_1st_MT tunnel-id=10, add address=10.10.10.1/30 interface=eoip2 network=10.10.10.0, add distance=1 dst-address=192.168.72.0/24 gateway=10.10.10.1. L2TP is an IETF standard for tunneling Point-to-Point Protocol (PPP) across any intervening network. Each type of device currently requires a different configuration method, below is a list of which configuration should be used on a device in order to use the benefits of hardware offloading: Consider the following scenario, you have a device with two or more switch chips and you have decided to use a single bridge and set up VLAN filtering (by using the/interface ethernet switchmenu) on a hardware level to be able to reach wire-speed performance on your network. L2TP merangkum PPP dalam garis virtual yang berjalan di atas IP, Frame Relay dan protokol lainnya (yang saat ini tidak didukung oleh MikroTik RouterOS). If you require the packet to be received on the interface and the device needs to process this packet rather than just forwarding it, for example, in case of routing, then it is required to increase the L2MTU and the MTU size, but you can leave the MTU size on the interface to the default value if you are using only IP traffic (that supports packet fragmentation) and don't mind that packets are being fragmented. Maximum Transmission Unit. Consider the following scenario, you have a bridge and you need to isolate certain bridge ports from each other. Bonding interfaces are not supposed to be connected using in-direct links, but it is still possible to create a workaround. If you are familiar withIperf, then this concept should be clear. Choose the proper transmit hash policy and test your network's throughput properly. doordash, wolt presentation. It sounds like you were pulling a Normis and sending UDP instead of TCP. routeros, mikrotik, eoip, layer2 tunnel, mpls, SHOP THE LATEST NETWORKING TECHNOLOGY FROM POPULAR BRANDS. The reason why some packets might not get forwarded is that MikroTik devices running RouterOS by default has MTU set to 1500 and L2MTU set to something around 1580 bytes (depends on the device), but the Ethernet interface will silently drop anything that does not fit into the L2MTU size. Bonding interfaces are not supposed to be connected using in-direct links, but it is still possible to create a workaround. The encryption shall be strong (at least AES128, SHA256, DH2048; shared secret is fine), which simple PPP type . Even over a 1500 byte MTU, the 1.7 Gbps we were able to hit is amazing considering it would probably take at least 20k to 30k USD to reach that kind of encrypted throughput with equipment from a mainstream network vendor like Cisco or Juniper. First step is to enable L2TP server: /interface l2tp-server server set enabled=yes use-ipsec=required ipsec-secret=mySecret default-profile=default The reason why this is happening is because of the testing method you are using, you should never test throughput on a router while using the same router for generating traffic, this is especially true when using Bandwidth test since it is only able to generate traffic on a single CPU core and also applies when using Traffic-generator, though it can run on multiple cores, but you are still adding a load on the CPU that reduces the total throughput. The EoIP protocol and recent enhancements. Layer 2 tunnel via IPSEC/IKEv2. We can see in the host table thatbridge2has learned these hosts. Create the tunnel interface and define the local and remote tunnel endpoints. we already know the cool layer 2 devices, which really help us reducing collision domain . Because of the broken MAC learning functionality and broken (R)STP this setup and configuration must be avoided. The reason is that as soon as you use any STP variant (STP, RSTP, MSTP), you make the bridge compliant with IEEE 802.1D and IEEE 802.1Q, these standards recommend that packets that are destined to 01:80:C2:00:00:0XshouldNOTbe forwarded. Each remote peer is defined in . This example demonstrates how to easily setup L2TP/IpSec server on Mikrotik router (with installed 6.16 or newer version) for road warrior connections (works with Windows, Android And iPhones). This type of setup is also used for VLAN translation. A network diagram can be found below: To better understand the underlying problems, let's first look at the bridge host table. If you follow MikroTik and RouterOS updates closely, you might have come across a new feature that was released in version 6.30 of RouterOS. Some unsupported modules might not be working properly at certain speeds and with auto-negotiation, you might want to try to disable it and manually set a link speed. 403269. Since (R/M)STP is not needed in transparent bridge setups, it can be disabled. The proper solution is to take into account this hardware design and plan your network topology accordingly. All devices are able to be configured with bridge VLAN filtering, but only a few of them will be able to offload the traffic to the switch chip. Access ports are configured using a pvid property. CryptoKey Routing - There isn't another tunnel or anything else we commonly use that uses this, so its not easy to compare to other things. As a result VLAN interface that is created on a slave interface will never capture any traffic at all since it is immediately forwarded to the master interface before any packet processing is being done. fConfiguration Details By - winbox Location A Rename two LAN cards for better understanding WAN >> RADIO/Fiber cable will connect here LAN >> LAN switch will connect here Setting IP Open New terminal in Client Location A / ip address add address=192.168..1/24 network=192.168.. broadcast=192.168..255 interface=LAN Sanjoy Banik ADN Telecom . 1500 byte MTU encrypted with IPSEC, And the results are in!!! ans = - chackeing every 10 second and after 2 fairules, the gateway is considered unreacheable - in case of failure of the gateway, routers pointing to that gateway will become inactive 3. routing protocols used within the same AS are referred to as exterrior . 10 Gbps is possible over EoIP, 10 Gbps over EoIP (Unencrypted with 9000 byte MTU), Video of10 Gbps over EoIP (Unencrypted with 9000 byte MTU), 7.5 Gbps over EoIP (IPSEC encrypted with 9000 byte MTU), Video of 7.5 Gbps over EoIP (IPSEC encrypted with 9000 byte MTU), 6.4 Gbps over EoIP (Unencrypted with 1500 byte MTU), Video of 6.4 Gbps over EoIP (Unencrypted with 1500 byte MTU), 1.7 Gbps over EoIP (IPSEC encrypted with 1500 byte MTU), Video of 1.7 Gbps over EoIP (IPSEC encrypted with 1500 byte MTU). Layer 2 tunnel via IPSEC/IKEv2 . over an IP network. MikroTik provides GRE (Generic Routing Encapsulation) tunnelthat is used to create a site to site VPN tunnel. This is a very common type of setup that deserves a separate article since misconfiguring this type of setup has caused multiple network failures. The EoIP tunnel protocol is one of the more popular features we see deployed in MikroTik routers. Use a proper testing method. As a result VLAN interface that is created on a slave interface will never capture any traffic at all since it is immediately forwarded to the master interface before any packet processing is being done. There is a way to configure the device to have all ports switch together and yet be able to use VLAN filtering on a hardware level, though this solution has some caveats. Also if a device behind ether3 is using (R)STP, then ether1 and ether2 will send out tagged BPDUs which violates the IEEE 802.1W standard. Packet flow with hardware offloading and MAC learning, VLAN filtering with multiple switch chips, https://help.mikrotik.com/docs/display/ROS/Layer2+misconfiguration, https://wiki.mikrotik.com/index.php?title=Manual:Layer2_misconfiguration&oldid=34338, Traffic going through only one LAG member, Device behind a bridge is unreachable with tagged traffic, BPDUs ignored by other RSTP enabled devices, Web pages are not able to load up, but ping works properly, 802.1x authentication (dot1x) not working, Traffic is being forwarded on different bridge split-horizons. Once established the tunnel can be bridged to physical adapters or other connections. If selected, then route with gateway address from 10.112.112.0/24 network will be added while connection is not established. The MikroTik config has 3 required config items for EoIP on each router vs double the steps with Cisco and the added complexity of troubleshooting IPSEC if you get a line of config wrong. Next step is to enable L2TP server and L2TP client on the laptop. Change the interface on which the VLAN interface will be listening for traffic, change it to the master interface: Consider the following scenario, you have a set of interfaces (don't have to be physical interfaces) and you want all of them to be in the same Layer2 segment, the solution is to add them to a single bridge, but you require that traffic from one port tags all traffic into a certain VLAN. L2TP incorporates PPP and MPPE (Microsoft Point to Point Encryption) to make encrypted links. Here is an example how R1 and R2 should be reconfigured: AP1 and ST1 only needs updated IP addresses to the correct subnet: Same changes must be applied to AP2 and ST2 (make sure to use the correct subnet): With this approach you create the least overhead and the least configuration changes are required. Note: Setting all bridge ports in the same bridge split-horizon will result traffic being only able to reach the bridge interface itself, then packets can only be routed. The proper way to tag traffic is to assign a VLAN ID whenever traffic enters a bridge, this behaviour can easily be achieved by specifying PVID value for a bridge port and specifying which ports are tagged (trunk) ports and which are untagged (access) ports. Maximum packet size that can be received on the link. Don't use Bandwidth-test to test large capacity links and don't run any tool that generates traffic on the same device you are testing. Devices onether1andether2need to send tagged packets with VLAN-ID 99 in order to reach the host onether3(other packets do not get passed towards VLAN interface and further bridged with ether3). In early years, Layer 2 VPNs were pretty popular and later on came Layer 3 VPNs which started picking up pace. MikroTik CCR1072-1G-8S+ Review Part 3 80 Gbps Throughput testing. Go to networking r/networking Posted by ip_addr Layer 2 Tunnel over Layer 3 Network I am trying to find the best solution for a campus network. This means you can tunnel L2 protocols like Ethernet, Frame-relay, ATM, HDLC, PPP, etc. 5. Packets coming fromether3toether1will be correctly sent out tagged and traffic will not be flooded inbridge1. Save products on your wishlist to buy them later or share with your friends. In order to avoid the trouble of double NAT, I would like to reconfigure the MikroTik hAP ac lite as a Layer 2 switch. LACP requires both bonding slaves to be at the same link speeds, Wireless links can change its rates at any time, which will decrease overall performance and stability. The BCP + MRRU hides the fragmentation, it transparently chops up and reassembles layer2 frames. In this case both endpoints can be any type of device, we will assume that they are both Linux servers that are supposed to transfer large amount of data. 802.1Q (or dot1q) tunneling is pretty simplethe provider will put an 802.1Q tag on all the frames that it receives from a customer with a unique VLAN tag. Full authentication and accounting of each connection may be done through a RADIUS client or locally. The information in this document was created from the devices in a specific lab environment. Now the question/issue is, can this be migrated to an over the in. Tue Jan 28, 2020 1:52 am. You should only use supported SFP modules. 0x9100. Consider the following scenario, you have decided to use optical fibre cables to connect your devices together by using SFP or SFP+ optical modules, but for convenience reasons you have decided to use SFP optical modules that were available. For redundancy, you connect all switches directly to the router and have enabled RSTP, but to be able to setup DHCP Server you decide that you can create a VLAN interface for each VLAN on each physical interface that is connected to a switch and add these VLAN interfaces in a bridge. Monitor command can be used to monitor status of the tunnel on both client and server. In such a scenario, you would have probably set interface MTU to 9000 onServerAandServerB and on yourSwitchyou have probably have set something similar to this: This is a very simplified problem, but in larger networks, this might not be very easy to detect. When this option is enabled, dynamic IPSec peer configuration and policy is added to encapsulate L2TP connection into IPSec tunnel. You decide that you want to test the link's bandwidth, but for convenience reasons, you decide to start testing the link with the same devices that are running the link. If the switch chip cannot find the destination MAC address, then the packet is flooded to all ports (including the CPU port). Similar behavior can be achieved using bridge filter rules. L2TP encapsulates PPP in virtual lines that run over IP, Frame Relay and other protocols (that are not currently supported by MikroTik RouterOS). Network diagram can be found bellow: Only the router part is relevant to this case, switch configuration doesn't really matter as long as ports are switched. VPLS over GRE then enables VPLS across an IP network. As the trunk port is used on both VLANs, you, Traffic is flooded between different VLANs, {"serverDuration": 140, "requestCorrelationId": "b595930f2db105d9"}, Traffic going through only one LAG member.
