CCNP routing service Summary

1. Converged data streams in the network, including voice and video data streams, voice application data streams, key task data streams, transaction data streams, route protocol data streams, and network management data streams.2. Three Phases of Cisco IIN: Integrated Transmission, integrated services, and integrated applications.3. Layer 3 of the Cisco SONA architecture framework: network infrastructure layer, interactive service layer, and application layer.4. Components of the Cisco enterprise architecture used to integrate the entire network: Campus, data center, branch, remote office staff, and WAN.5. The traditional hierarchical network model and its three layers: core layer, distribution layer and access layer.6. Cisco enterprise Composite Network Model and its three functional areas and related modules.A. enterprise parks: building module, building distribution module, core module, edge distribution module, server module, and management module.B. Enterprise edge: E-commerce, enterprise Internet, VPN, remote access, and WAN.C. Edge of service providers: ISP, PSTN, and frame relay/ATM.7. There are two methods to achieve network change: ad hoc and structured.8. Four models used in the IT service life cycle: Cisco lifecycle service PPDIOO), ITIL, FCAPS, and TMN.9. Develop an implementation plan, which is part of the network design phase and contains the following content:A. Network InformationB. required toolsC. required resourcesD. Implementation TaskE. Verify the taskF. Performance measurement and results10. The network aggregation is complete, that is, when the route tables of all routers in the network are synchronized and the packets are routed to all target networks. Aggregation time refers to the time required by all routers in the network to reach an agreement on the new topology.11. For Static Routing features and configurations, use the global configuration command router odr. It uses CDP in the Branch section). The network information is transmitted between the router and the central router.12. The dynamic routing protocol has the following features:
A. measurement value: the value of the route protocol used to measure the path to the destination.B. Configuration: Use the global configuration command router protocol.C. Distance Vector Routing: All routers regularly send the route table or a part of the route table to the neighbor router.D. link Status routing: when the status of each vro changes at its interface link, the changed status is sent to all other vrouters or a part of the network, which is called a region.E. Advanced Distance Vector Routing: the Protocol only sends the changed information, which is similar to the link status information) and only sends the information to the neighbor router, which is similar to the distance vector routing protocol ).F. Update the classlike Protocol: The subnet mask is not included. Classless Inter-Domain Routing (r00001) does not support VLSM and unconnected subnets, and must be automatically aggregated to the classification address at the network boundary.G. classless routing protocol update: contains the subnet mask. Classless routes such as r12002, VPN, and OSPF support VLSM and unconnected subnets without the need to automatically summarize network boundaries.13. The features and configurations of r1_1 and r1_2 are as follows:A. Global configuration command router rip enable RIPB. to only accept and send RIP version groups, use the vro configuration command version {1 | 2 }.C. The vro configuration command network-number enables RIP on the pretext of the specified network and notifies the network connected by these interfaces.D. The interface configuration command ip rip {send | receive} version {1 | 2 | 1 2} controls the RIP version used by each interface.E. Disable auto-summary In the vro configuration command.F. interface configuration command ip summary-address rip network-number mask specify the network number and subnet mask to meet specific aggregation requirements.14. The routing table of the Cisco router filler is based on the following principles:A. Valid next hop IP Address: the router first checks whether the next hop IP address of the route is valid.B. Measurement Value: if the next hop is valid, the routing protocol selects the Optimal Path to the given parent location based on the minimum measurement value and provides it to the route table.C. management Distance: if multiple routes to the same network have the same prefix from different routing sources ), the router determines which route to add to the routing table based on the Management Distance of the route source. The management distance is 0-, and the smaller the management distance, the higher the reliability of the Protocol. Add the route entry with the minimum management distance to the route table, and other routes will be rejected.F. Prefix: the prefix for the router to view the announcement. In the routing table, there can be a route to the same network but with different prefixes.15. compare various IP routing protocols. In the enterprise Composite Network Module, multiple protocols may be used. In an enterprise network, we recommend that you use OSPF and OSPF. BGP must be used to connect to an autonomous system over the Internet.
