How to implement ospf in golang
Article Introduction:In recent years, the OSPF (Open Shortest Path First) protocol has become increasingly familiar as a WAN routing protocol. It is a link state-based routing protocol whose goal is to implement the shortest path tree algorithm to improve routing efficiency. In this article, we will introduce how golang implements the OSPF protocol. 1. Introduction to OSPF OSPF is an open link state protocol belonging to the TCP/IP protocol suite. It supports hierarchies between routers and subnets, while also supporting different network services such as IP

How to analyze the specific differences between the two addresses 224.0.0.5 and 224.0.0.6 in OSPF
Article Introduction:224.0.0.6 refers to the multicast receiving address of DR and BDR in a multi-access network, and 224.0.0.5 refers to all interfaces running the OSPF process in any network that belong to this group, so all multicast data of 224.0.0.5 are received. Bag. Focus on understanding what kind of multicast data packets belong to a certain group and what kind of multicast data packets are received. For example, DR/BDR belongs to the group (Group) with the multicast address 224.0.0.6, so it receives multicast data packets with the destination address 224.0.0.6. You can understand why multi-channel access can prevent excessive processing of information by setting DR/BDR (because the receivers belonging to a certain group (referring to the OSPF interface) will only be stripped to the second layer without further processing, thus eliminating the need for very

Turn your CentOS into an OSPF router
Article Introduction:Introduction Quagga is an open source routing software suite that turns Linux into a router that supports major routing protocols such as RIP, OSPF, BGP, and IS-IS. It has full support for IPv4 and IPv6 and supports route/prefix filtering. Quagga can be a lifesaver in case your production router ever goes down and you don't have a spare but are waiting for a replacement. With proper configuration, Quagga can even function as a production router. In this tutorial, we will connect two branch office networks assuming there is a dedicated line connection between them (for example, 192.168.1.0/24 and 172.17.1.0/24). Our CentOS is on both ends of said private link
