How to resolve Cisco routing protocol conflicts?

the two-protocol stack is running, it does not mean that the network and application-oriented services can be integrated into one another, and from the actual process of connecting the site, this work is much more complicated than it looks. DNS servers need to be queried, packets need to be able to pass through routing, TCP sessions need to be initiated, and packets need to be exchanged at all times. For

Concept and features of OSPF Routing Protocol

1. OSPF features Fast convergence;Able to adapt to large networks;Able to correctly process error routing information;The use area can reduce the CPU burden on a single router and form a structured network;Supports classless routing, full support for classless network, variable length subnet, and other classless features;Supports Load Balancing across multiple paths;Multicast addresses are used for informa

How to configure the multi-area OSPF routing protocol in the network

, allowing for the logical connectivity of those areas that are physically partitioned. 4, the router connected to the autonomous system is called Autonomous system boundary router ASBR, through ASBR to learn the routing information outside the OSPF autonomous system (such as static routing, RIP, etc.) 5, a network segment can only belong to the same area All right, we got it. Later, we carried out our e

The RIP Protocol applies the offset to the routing selection scale.

The offset list is used to obtain paths through RIP and increase the inbound and outbound distances. This is to provide a local mechanism to increase the routing selection scale value. You can also restrict the offset list for the access table or interface. To add a route selection scale value, run the following command in vro Setting Mode: Related Articles] Sets inter-group latency using the RIP

How does the routing protocol publish timeout resolve?

A link state broadcast is a grouping used by the link state Protocol, which includes information about the cost of neighbors and channels, and each ospflsa has a lifetime indicating whether the LSA is still valid. Once the LSA reaches the maximum lifetime, it is discarded, and this article is going to show you how to solve the timeout if it happens. First, the network environment Network, in Mercury A, mercury B and Mercury C, the configuration of t

Introduction to the routing transparency protocol (TRILL)

virtualization environment, most networks are limited by STP restrictions and must build multi-layer networks, that is, the Layer 2 architecture of the edge or access layer and the layer 3 network of the aggregation layer. Finally, set the Core routing protocol on the other layer of the network architecture. This is the main method of network design over the past decade. 6. The idea of this design is to pa

13th set IP routing principle and RIP Protocol

This video is the first video course of some network-related training courses for Linux System Engineers. The main content is the IP routing principle and the RIP Protocol. At work, I found that many Linux O M personnel encounter bottlenecks due to lack of basic network knowledge, and it is still a common phenomenon thanks to the inapplicable education system in China ). From the perspective of public we

Discovery and restoration of the neighbor in the OSPF Routing Protocol

Although VPN is a distance vector routing protocol, it adopts a non-periodic and partial update method during the update process, rip and IGRP use periodic updates to test the neighbor status. Therefore, it is necessary to use a method to verify the existence of the neighbor. The "hello" packet is used in the network. It is sent every five seconds. Because the time is much less than 30 seconds of RIP and 90
