bgp routing protocol

The OSPF dynamic routing protocol is worth learning a lot. Here we mainly introduce the internal zone routers, including the area border routers and backbone routers. One reason for OSPF's scalability is its route update mechanism. The OSPF dynamic routing protocol uses LSA to share

(External Gateway Protocol) and the Border Gateway Protocol BGP (Border Gateway Protocol). BGP is a newer Protocol and is gradually replacing EGP. Static Routing

Routing dynamic protocol (RIP) and RIP Routing RIP route definition: it is used to automatically transmit route entries between different routers. a shortest and loop-free forwarding path to the target network has been calculated.Lab name: RIP routeLab Environment R1/R2/R3/R4PC1/PC2Experiment ideas1-configure the corresponding IP address, subnet mask and gateway

routing is based on whether in an autonomous system and can be divided into internal Gateway Protocol (IGP) and External Gateway Protocol (BGP), the common internal Gateway Protocol has RIPOSPF and other external gateway protocol

RIP: A distance vector protocol, the distance is distance, the number of hops to represent, vector is vectors, interface to represent. Based on the Bellham-ford (distance vector) algorithm, belongs to the IGP (Internal Gateway Protocol) class. RIP is divided into the class routing protocol (RIPV1) and the No-class

database, and then produces a routing table based on the database. Moreover, the transmission of OSPF link state information is not based on UDP or TCP, but rather as a separate protocol that has a specific value in the Protocol field in the header of the IP data.In an OSPF-based routing table, there is only one optim

VBR directly broadcasts the summarized data to all vrouters in Area 0. OSPF does not allow interconnection between zones greater than or equal to 1. All such interconnection must pass through Zone 0. Therefore, it means that a VBR connects a non-zero zone with Zone 0. 3. Backbone Router The backbone router is responsible for maintaining the backbone topology information and spreading the summarized topology information for each other area in the autonomous system. Figure 4 shows how the backbo

IP address of an external route must be continuous. Route reduction is completed through the sub-commands under "router ospf", and this command is only valid on the VBR of the autonomous domain:Summary-address ip-address mask For example, router B injects an external route into the OSPF domain, and the injected subnet range is 126.1.96-127. To perform route reduction, you must perform the following operations on vrob B:RouterB #Router ospf 102Summary-address 126.1.96.0 255.%224.0Redistribute

, such as BGP (Border Gateway Protocol) to exchange routing information. The second is that the summary route is good and is added to the static route of the new network in this router. Any data packet that uses this route to reach this router will be sent to the new network, but OSPF does not know its existence. To this end, although we "re-allocate" These

The dynamic routing protocol can be divided into the following two categories based on the operating region: 1.

This is not the root of the problem. The root cause of the problem is how to use the two effectively, so that the two can become partners rather than competitors. What's going on?We know that
