伊林思_工业无线路由器OSPF链路类型(Link... 工业无线路由器OSPF链路类型(Link Type) 巧玲珑OSPF确实因为考虑问题的全面,而导致路由协议的复杂,OSPF不仅因为不同的二层链路层介质定义了不同的OSPF网络类型(Network Type),还因为链路上的邻居,而定义了OSPF链路类型(Link Type) 。 OSPF网络类型(Network...

工业4G路由器BGP邻居的flaping •工业路由器通过IGP学到对方loopback,并用looback建EBGP邻居 •又在BGP中通告此loopback。此时BGP邻居会出现flaping R1和R2之间运行一个IGP协议,比如说EIGRP。将环回口都宣告进去,这样R1和R2相互之间就有对方环回口的工业级路由器路由了,然后再用环回口建立EBGP邻居关系。最后再把2.2.2.0和1.1.1.0的环回口宣告进BGP。这时你会发现工业无线路由器BGP路由会发生flapping。 原因一:无线路由器 •首先R1和R2之间运行了EIGRP,学到对方的环回口工业级无线路由器路由是一条EIGRP路由,管理距离是90 •而当这两个环回口宣告进BGP后,R1和R2又通过BGP学到对方环回口路由,管理距离是20 •这时,全网工业级路由器BGP路由由于管理距离最小,会进入全网工业路由器路由表,取代EIGRP路由 •问题在于,现在的全网通工业路由器BGP路由是有问题的,下一跳是不可达的 R2收到的1.1.1.0的BGP路由下一跳是R1的环回口1.1.1.1 R1收到的2.2.2.0的BGP路由下一跳是R2的环回口2.2.2.2 •BGP有一个检查机制,每60S检查一次BGP路由,看是否有效,60S后就会检查到这些工业级全网通路由器路由并设为无效 •BGP路由无效以后,在路由表中就没有了,EIGRP路由又起作用了。 •有了EIGRP路由,BGP路由的下一跳有可达了。又有效了。 •BGP邻居有效以后,又会抢占了EIGRP路由的地位,又会导致全网通工业级路由器BGP路由下一跳不可达。 原因二:4g路由器 •首先R1和R2之间运行了EIGRP,学到对方的环回口工业全网通路由器路由是一条EIGRP路由,管理距离是90 •而当这两个环回口宣告进BGP后,R1和R2又通过BGP学到对方环回口路由,管理距离是20 •这时,工业级全网路由器BGP路由由于管理距离最小,会进入路由表,取代EIGRP路由 •问题在于,现在的工业4G路由器BGP路由是有问题的,下一跳是不可达的 R2收到的1.1.1.0的工业级4G路由器BGP路由下一跳是R1的环回口1.1.1.1 R1收到的2.2.2.0的BGP路由下一跳是R2的环回口2.2.2.2 •路由不可达就造成两个邻居之间没法发送keeplive •180S后BGP邻居关系超时,并DOWN掉。这时EIGRP路由又起作用了。 •有了EIGRP路由,BGP邻居关系又可以建立了。 •BGP邻居有效以后,工业全网路由器BGP路由又会抢占了EIGRP路由的地位,又会导致BGP邻居再一次DOWN掉。 标签:全网通路由器 ...

伊林思:工业4g路由器区域分离你清楚吗? 工业4g路由器区域分离 区域分离的操作与区域合并的正好相反。区域分离可以将原有的一个区域分离为两个不同的区域。如下图所示,R1与R2都为L1/2工业路由器。起初R1和R2属于同一个区域中,都拥有相同的区域地址49.0001,之间形成了L1和L2邻接关系,共享相同的L1和L2链路状态数据库。现在需要将这两个区域分离开。与区域合并一样,可以先赋予R2两个全网通工业路由器NET地址,区域地址分别为49.0001和49.0002。之后再将R2原先区域地址为49.0001的NET地址删除,这时由于R1和R2处于不同的区域,L1邻接关系将不存在,但L2邻接关系和L2链路状态数据将保留,此时便完成了全网通工业级路由器区域分离。 重编址 重编址过程与区域合并、区域分离相似,重编址可能需要清除一些或者全部工业级路由器的区域前缀,用新的区域前缀代替。如下图所示,现在希望将原先的49.0001区域迁移到49.0002区域,这就需要更改工业级无线路由器上的区域地址。R1和R2属于同一个区域49.0001中,要将R1和R2迁移到49.0002区域中,可以为R1和R2都赋予两个NET地址,两个NET地址包含不同的区域地址,49.0001和49.0002,然后依次删除R1和R2的包含49.0001区域地址的NET地址,这样就实现了工业无线路由器新的NSAP地址的无缝、无冲突的重新配置。 注意,IS-IS多宿主与IP中的辅助地址(secondanaryIP)是不同的,辅助地址可以在同一条工业级全网通路由器链路上创建多个隔离的逻辑子网。另外,辅助IP地址是在一条链路上配置多个子网。 工业无线路由器NSEL NSEL定义了网络层服务的用户,工业全网通路由器路由层是特殊的网络层服务用户,它的NSEL值为0。之前多次提到,在IS-IS工业4G路由器上配置的NSAP地址采用00作为NSEL,这时NSAP地址被称为NET。NSEL的值与IP报头中的协议类型或TCP/UDP报头中的TCP、UDP端口号类似,NSEL帮助网络层把数据发送到适当的应用程序或服务。在OSI分层模型中,网络层服务的是传输层。目标不是路由进程的CLNP数据包具有非0的NSEL值的NSAP地址,表示节点需要将数据发送到传输层。我们在使用IS-IS进行工业级4G路由器IP路由选择中,只要记住始终保持NSEL为00即可。全网通4g路由器

Nokia #India announces #5G #IoT for #SmartCities

Category : 其他, 技术相关

The Finnish company showcased more than 60 different use-cases of these technologies at its annual Innovation Day in Bengaluru, including those that are already live and ready for use as well as ones that aren’t live yet.

Nokia’s research and development office in Bengaluru, which has around 5,000 employees, creates solutions for both its Indian and international markets. Its new IoT range, though, will focus more on Indian clients, especially governments.

“5G and IoT are going to be the future trends that we see in the marketplace. While from an India standpoint it’s still an early stage for 5G to happen, IoT is taking a bit of a step forward in terms of adoption here,” Randeep Raina, chief technology officer for Nokia India said in an interview on Wednesday.

“There are certain initiatives led by the government right now in the form of digital India and smart city programs. IoT could be one of the enablers to make cities a bit safer and smarter. It’s with that intent that we’d put a theme out here on this innovation day,” he said.

The three main solutions, or use-cases, showcased by the company on Wednesday were video analytics of real-time city surveillance, a public safety service that can be deployed at railroad crossings and a smart parking service.

Based on real-time city surveillance via cameras deployed at various public locations Nokia’s IoT solution will be able to provide clients – mostly governments and policing authorities – with data analysis. The analysis includes everything from identifying anomalies, such as incorrect pedestrian crossings, to tracking traffic patterns.

Its public safety solution uses sensors, beacons and cameras and is aimed at keeping pedestrians from straying across the path of oncoming trains at railroad crossings. This service will both warn people crossing railroads on foot of an oncoming train as well as alert the authorities and issue notice of a fine in case people cross even after receiving a warning. The warning messages will appear on any device using any service provider and are not app-based, i.e. the user will not need to install an app to see the messages.

Nokia’s smart parking solution will target organized parking lots that can use it to fully automate the process – from identifying a car on entry and guiding the driver to free parking spots through an app, to recording the number of hours a car is parked at the lot and bill payment online via the app.

Roughly two months ago, auto components supplier Bosch Ltd also launched solutions targeted at creating smart cities, including a smart parking service that will help commuters find space in crowded areas. The German company has other similar solutions that are, again, aimed at assisting traffic policing and citizen safety and security systems.

E-Lins H685wrt quick start

Category : 产品文章, 伊林思产品FAQ

Before Installation and Configuration

1. H685 router has different version. Study your router version before installation.

2. For GSM/GPRS/EDGE/HSDPA/HSUPA/HSPA/HSPA+/4G LTE version, please get a SIM card with data business.

3. For CDMA2000 EVDO/CDMA1x version, please get a UIM card with data business or inform us before order if the network uses non-ruim (nam-flashing).

4. Make sure the sim card or uim card is with enough data business and balance.

5. Make sure the signal is good enough where you test or install the router. Weak signal will make the router no work. If you find your signal strength is not good, please contact us for high gain antenna.

6. Different countries and carriers use different network band and frequency. E-Lins packs units with free world-wide-use antenna. It can work, but the data speed or signal may not be good at your sites. Please buy dedicated high gain antenna from your local suppliers or contact E-Lins to OEM/ODM the antenna.

Notes: This quick start is for GSM/GPRS/EDGE/HSDPA/HSUPA/HSPA+/TD-SCDMA/4G LTE network only. For EVDO network or CDMA network, please refer to manual or contact us freely.

Step 1) Confirm the sim card if can work with other 2G/3G/4G router or modem. If the sim card can not work, the router will not work correctly.

Step 2) Connect the H685 Router LAN port to a PC via RJ45 cable. Make the PC automatically to get the IP, Submask, DNS. The PC will be get a IP of 192.168.1.xxx.

Step 3) At PC web browser, please type: http://192.168.1.1 Username: admin Password: admin
