I. Redistribution 1: redistribution means that when an organization runs multiple routing protocols, it must notify the network learned by one routing protocol to the other by the selection protocol, when each endpoint can reach another point, this process is redistribution. Although multiple routing protocols are run in the Organization, each internal routing protocol is considered to be the only internal routing selection protocol in the, OSPF recognizes that OSPF is an external route from the

At present, Cisco routers have a very high market demand. Here we mainly introduce the use of OSPF to solve the defects of the RIP route information protocol, including the OSPF Authentication Method. OSPF is also an open version of The Link Status Protocol. In practice, OSPF is often used in some large and hybrid networks. In the previous article, I talked about the defects of the RIP Protocol. The reason

Many people may not have a special understanding of Static Routing and dynamic routing protocols. Here we mainly introduce the RIP and OSPF routing protocols. Static Routing is a fixed route table configured on the router. The static route does not change unless the network administrator intervene. Because Static Routing cannot reflect network changes, it is generally used in a network with a small network size and a fixed topology. Static Routing is

TopologyObjective: Configure RIPv2 Verify Connectivity BackgroundAlthough RIP is rarely used in modern networks, it's useful as a foundation for understanding basic network routing. In this activity, you'll configure a default route, RIP version 2, with appropriate network statements and passive Inter Faces, and verify full connectivity.Step 1:configure on R1.A. Use the appropriate command

"inter-network.The routing action includes two basic items: path finding and forwarding. The routing algorithm is used to determine the optimal path to the destination. Because different routing protocols and routing algorithms are involved, it is relatively complicated. To determine the optimal route, the routing algorithm must start and maintain the route table containing route information. The routing information varies depending on the routing algorithm used. The routing algorithm fills in

routes independently. OSPF, a flat and simple network topology, is characterized by its dynamic, open, and global nature. This is an excellent feature for large networks with complex topology structures. For example, on a complex Internet, if a router breaks down, other routers can be automatically adjusted immediately without the network administrator's effort to detect and reset the path; however, if it runs on a flat network with a relatively simple topology, this advantage becomes a critica

"TCP/IP Detailed volume 1"2. "TCP/IP protocol family"3. The 5th edition of computer networkOSPF(Open Shortest path first opening shortest path priority )is an IGP (internal Gateway Protocol) protocol that is used primarily as an in-house (autonomous system). The protocol is based on aLink State, and

the Serial 0 address on Router1 is 192.200.10.5 and 192.200.10.4/30 belong to a directly connected network, there is a path to access 192.200.10.4/30, so you do not need to add a static route on router1. At the same time, because Router3 is no longer connected to other routers except router Router2, you can also assign a default route to it to replace the above static routing configuration, ip route 0.0.0.0 0.0.0.0 192.1.0.65, that is, as long as the path to the specific destination address is

network topology changes. Dynamic Routing is suitable for networks with large networks and complex network topologies. Of course, various dynamic routing protocols occupy network bandwidth and CPU resources to varying degrees. Static Routing and dynamic routing have their own characteristics and applicability. Therefore, dynamic routing is usually used as a supplement to Static Routing in the network. When a group is used to find the route in the vro, The vro first searches for the static route

Internal Gateway Protocol: Gateway Protocol, also known as routing Protocol, is a mechanism for sharing routing information between routers, which allows routers to exchange routing information to maintain their respective routing

-nat: Similar to Dnat, but supports multi-target forwarding;It is forwarded by modifying the target address of the request packet to a certain RS rip selected by the scheduling algorithm;Architectural Features:(1) RS should use a private address, that is, RIP should be a private address; Each RS gateway must point to the dip;(2) The request and response messages are forwarded through the Director; in high-l

because of some other mechanism, even if it shows 15 minutes, it may not be in a minute.By default, the SYN status time-out is 1 minutes, the timeout for the established state is 15 minutes, the fin state has a timeout of 1 minutes, and the UDP state has a timeout of 5 minutes.

stack in the kernel. As you can imagine, this needs to be done in the kernel module, and such filtering and forwarding rules are defined by the Administrator, therefore, LVS is a two-stage architecture design. In the kernel space, "ipvs" is used, while in the user space, "ipvsadm" is used to define cluster service rules ". This makes it easy to think of iptables. Three forwarding modes of LVS: LVS-NAT: Network Address Translation LVS-DR: Direct routing LVS-TUN: IP tunneling VIP: IP address used

within 9 0 seconds, the adjacent site is considered inaccessible. Every 30 seconds, the distance vector routing protocol sends the entire route selection table to the adjacent site to update the route selection table of the adjacent site. In this way, it can collect a list of networks from other sites (directly connected or connected in other ways) for route selection. Distance Vector Routing uses the number of hops as the metric value to calculate the number of routers that need to pass to the

For the router protocol this term, probably many people have been familiar with, especially the current network development quickly, Internet Router Protocol is also constantly improving, but also appeared a lot of new features. The wide application of information technology in various fields has promoted the rapid development of information exchange network, in which the Internet is the biggest beneficiary. The main node equipment of the Internet network is the router, which determines the fo
