There are many other things worth learning about the vro protocol. Here we mainly introduce the features of IS-IS, including the features of the Border Gateway Protocol and BGP. While IAB works on OSPF, ISO works on IS-IS. At the end of 1980s and the beginning of 1990s, each person in the Open Systems Interconnection (OSI) group could replace TCP/IP. At that time, the integrated IS-IS was proposed. Although IS-IS was originally used for the OSI Router

Reservation Protocol), which distributes a portion of the bandwidth to multimedia signals. Other protocols are not allowed to occupy the bandwidth regardless of the congestion. These solutions can effectively improve the transmission quality. RIP, OSPF, and BGP protocols A large number of Routing protocols running on the Internet are RIP (Routing Information Protocol-Routing Information Protocol) and OSPF (Open Shortest Path First -- Open Shortest Pa

Many people may be familiar with the term Router Protocol, especially the rapid development of the network, the Internet Router Protocol is constantly improved, and many new features are also emerging. The wide application of information technology in various fields has promoted the rapid development of information exchange networks. Internet is the biggest beneficiary. The main node and device of the Internet network are routers. The router technology determines data forwarding through routing.

, OSPF, and BGP protocol router protocols that are running on the internet today are RIP, OSPF, and BGP. RIP, OSPF is an internal gateway protocol that applies to the operation of a single ISP's unified router protocol, and a network operated by an ISP is called an autonomous system (AS). BGP is a router protocol between autonomous systems and an external gatew

Calico Architecture Calico is a three-tier data center network solution and facilitates integrated OpenStack, an IaaS cloud architecture that delivers highly efficient and controllable communication between VMS, containers, and bare-metal. Combined with this picture above, we've been through Calico's core com

RoutingAlgorithmTo calculate and determine the optimal transfer path to the destination. The routing protocol is divided into the Internal Gateway Protocol (IGP) and the external Gateway Protocol (EGP) based on the internal or autonomous system running in an autonomous system ). For example, the routing information selection protocol (RIP) and the Open Shortest Path Priority Protocol (OSPF) are the internal gateway protocol, and the Border Gateway Protocol (

router that provides users with a connection to the PE router; the PE router is the operator's edge router, that is, the Label Edge Router LER In the MPLS network ), it processes the VPN data from the CE router or the label exchange path LSP according to the stored route information and forwards the data. It is also responsible for exchanging route information with other PE routers; P router is the main router of the carrier network, that is, the label exchange router LSR In the MPLS network. I

) grouping, confirming the grouping of link updates.To enable OSPF to be used in large networks, OSPF divides an autonomous system into smaller ranges called regions. Represents an autonomous system divided into 4 regions. Each region has a 32-bit area marker (in dotted decimal notation)Of course, a region can not be too large, the router in a region should not be more than 200.The advantage of dividing the region is that the scope of the exchange of link state information using flooding is conf

I wonder why we should not study the business model of the civil aviation industry. The separation of management right and experience right means that the airport manages the airport, the aviation business manages the aviation business, and the airport will only achieve a win-win situation, the aviation business will only compete, and the ultimate benefit

vro. Why don't you choose one of them? The reason is as follows: Because the telnet command uses TCP packets, the following situation may occur: A router interface is down due to a fault, but other interfaces can still be telnet, that is, the TCP connection to this vro still exists. Therefore, the selected telnet address must never be down, and the virtual interface meets this requirement. Because this type of interface does not require interconnection with the peer end, the address of the loop
