CCNP routing service Summary

CCNP routing service Summary 1. Data Streams in the integrated 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. Www.2cto.com 5. 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. Www.2cto.com 9. develop an implementation plan, which is part of the network design phase and contains the following content:. network Information B. required tool c. required resources d. implementation Task e. verify task f. performance measurement and result 10. the network aggregation is complete, that is, when the route tables of all routers in the network are synchronized and 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. Static Routing features and configurations (using the global configuration command router odr), it uses CDP to transmit network information between the branch (remote) router and the central router. 12. The characteristics of the Dynamic Routing Protocol are as follows: a. Metric value: the route protocol is used to measure the value of 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 part of the route table) to the neighbor router. D. link Status routing: when the status of each vro changes in its interface (Link), the status is sent to all other vrouters or part of the Network (this is called a region) all other routers in. E. Advanced Distance Vector Routing: the Protocol only sends the changed information (similar to the link status information) and only sends the information to the neighbor router (similar to the distance vector routing protocol ). F. Update the classlike Protocol: The subnet mask is not included. A class protocol (with 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 routing (such as RIPv2, VPN, and OSPF) supports 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:. the global configuration command router rip enables RIP B. to only accept and send a RIP version group, 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. Www.2cto.com e. router configuration command no auto-summary disable auto summary. F. interface configuration command ip summary-address rip network-number mask specify the network number and subnet mask to meet specific aggregation requirements. 14. When using the route table of the Cisco router filler, the following principles are used: 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 are learned from different route sources (with the same prefix ), 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.
