goes into the router management interface is different, and if you have previously been modified, you can restore the initial state of the device by pressing the recovery key. Access to the router management interface is the first task is to modify the password, passwords do not use full digits, preferably with the letter, the number is more secure. After the password has been modified, the device will reboot more than once. After reboot, we can cho

VPN clients can be provided Internet access by forwarding the traffic of the VPN user to the ISP's Internet network management. Implemented by creating a static route in the VRF of the PE router and specifying the next hop in the global routing table. The key to doing this is to specify the global keyword, so that the

In the vro function indicators, you should be unfamiliar with some Internet Protocol Descriptions. Generally, when using vrouters, you only care about the vro settings and configurations, as well as some IP address problems, in today's article, we will list all the router function indicators. Routing Technology: full access to router function indicators PPPOE sup

hire a large number of high-level technical personnel to maintain the network. Recently, Alpha, a well-known network equipment manufacturer, has launched a new fiber-optic Broadband Router for Internet cafe customers. This product model is Alpha AFR-R1602, is specially designed for large and medium-sized Internet cafes Broadband Router. In terms of appearance, Alpha AFR-R1602 is black-black and can provid

of BGP routes on the INTERNET, it is not feasible to re-distribute BGP routes to OSPF without a policy, OSPF supports a maximum of 10 thousand route tables and consumes a lot of router memory. Therefore, this method is generally not used!There is a public router on the INTERNET, you can view the above route table, just telnet on the route-server.ip.att.net addre

is the way it is, so it's not my personal nonsense. But I play with the DXR a little bit different ...The longest mask logic is advanced to the moment of insertion. For general operating systems such as Linux, the routing table cost is mainly concentrated on "longest mask match", because in the process of IP routing, the input is only a IPv4 address, that is, th

algorithm, according to the length of the mask to organize hash table, matching order from 32-bit mask down, For the trie organization algorithm, the situation is similar, see the Internet Routing table lookup algorithm overview-hash/lc-trie Tree/256-way-mtrie tree.For the search, especially the hash algorithm, it is

The ER series routers are available in three modes: NAT mode, route mode, and full mode. The differences and applications of the three modes are as follows:NATModeIn NAT mode, when the DMZ port is in Wan mode or LAN mode, the mode relationships between interfaces are also different.1DMZ port is in Lan modeThe LAN and WAN are in NAT mode, and the DMZ and WAN are also in NAT mode. That is, the IP address of the LAN or DMZ is converted to the IP address

to organize hash table, matching order from 32-bit mask down, For the trie organization algorithm, the situation is similar, see the Internet Routing table lookup algorithm overview-hash/lc-trie Tree/256-way-mtrie tree.For the search, especially the hash algorithm, it is inevitable to compare, the results are either 0

gateway also fails, TCP/IP continues to attempt to use the next default gateway in the list, returning to the beginning of the list after the entire list has been tried, and starting with the first default gateway.Dead gateway detection monitors only TCP traffic and does not switch the default gateway if other types of traffic fail. In addition, TCP is an end-to-end protocol, so even if the current default gateway is fully functional, the local computer's TCP communication failure may also caus

host D otherwise is indirect delivery execution (3).(3) If a specific host route with destination D in the routing table is routed to the next hop router indicated in the routing table, the datagram is executed otherwise (4).(4) If there is a route in the routing

methods of assembly:The grouping may reach the destination host through a different transmission path. When different slices belonging to the same group arrive, they appear in a disorderly order, or are blended with other groupings. First of all, according to the identification field will belong to the same group of all the slices out, the host allocates a storage buffer when the first shard arrives, when the datagram after the next Shard arrives, the data according to the slice displacement is

when the first shard arrives, when the datagram after the next Shard arrives, the data according to the slice displacement is copied to the buffer memory at the specified location, when all the shards arrive, the original datagram is restored.3) How the routing table is builtThe general router only needs to record the subnet mask, destination network address, next hop router address and router forwarding p

multiple table items are matched. It can also be understood that the most bits items are matched. The operation of the IP address to the binary string is to convert the 4 integers in the address (which must be within the range of Y to 255) into 8-bit binary numbers, sequentially stitching together, to get a 32-bit binary string. For example, 192.168.1.253 is converted to a binary string after 11000000 10101000 00000001 11111101 We use the destination

The route command for the Linux system is used to display and manipulate the IP routing table (show/manipulate the IP routing table). To achieve communication between two different subnets, you need a router that is connected to two networks, or a gateway to two networks.In Linux systems,
