OSPF protocol is used in large network. OSPF is shortened form of Open Shortest Path First. It is a dynamic routing protocol used in Internet Protocol networks. Specifically, it is a link-state routing protocol
OSPF Network Stability: Router ID Design Router ID selection is the first task in OSPF network design and implementation. As a link-state routing protocol, OSPF calculates routes based on LSAs. All OSPF routers on an OSPF network send and flood LSAs to the entire network. In this way, each...
1.point-to-point的link ID是邻居的RID 2.transit network的link ID是DR的接口地址 3.stub network的link ID是IP网络号 4.virtual link的link ID是邻居的RID LSA类型2(network LSA),如下图: 类型2的LSA只在一个区域里传播,不会穿越ABR.描述了组成transit network的直连的路由器.transit network直连至少2台O...
P2P: If the link layer protocol is PPP, HDLC, or LAPB, OSPF defaults the network type to P2P. Without changing the layer protocols, you can change network types and configure OSPF features to flexibly build networks. Pre-configuration Tasks Before configuring OSPF attributes in diff...
OSPF(Open Shortest Path First)是一种开放性最短路径优先协议,属于网络层协议。它是一个基于链路状态的路由选择协议,主要用于在自治系统内计算出最短路径。而RIP(Routing Information Protocol)是一种距离向量路由协议,属于应用层协议。它是一个简单且较为老旧的协议,通过跳数来选择最佳路径。

this is going to open up an entire discussion on this topic as has been seen in the past. Essentially, what i find most people concider are the following Application Layer Routing protocol RIP BGP Network Layer Routing Protocol EIGRP OSPF Layer 2 (i believe) IS-IS The reasoning for this ...
Configuring OSPFv3 network types Restrictions and guidelines for OSPFv3 network type configuration Based on the link layer protocol, OSPFv3 classifies networks into different types, including broadcast, NBMA, P2MP, and P2P. · If any routers in a broadcast network do not support multicasting, you ...

configuration steps when you run the Open Shortest Path First (OSPF) Routing Protocol between Provider Edge (PE) and Customer Edge (CE) Routers. It presents a network scenario that depicts the use of Downward Bit (DN), which is an option in the Link State Advertisement (LSA) and Dom...
