CCNP Routing Service Summary

1. The integration of data flow in the network, which includes voice and video data streams, voice application data flow, mission-critical data flow, transaction data flow, routing protocol data Flow and network management data flow.

The three phases of 2.Cisco iin: Integrated transport, integrated services, and integrated applications.

The three tiers of the 3.Cisco SONA Architecture Framework: The network infrastructure layer, the interactive service layer, and the application tier.

4. Part of the Cisco Enterprise architecture for integrating the entire network: parks, data centers, branch offices, remote office personnel, and WANs.

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 Park: Building module, building distribution module, Core module, Edge distribution module, server module and Management module.

B. Enterprise Edge: E-commerce, corporate Internet, VPN and remote access, WAN.

C. Service provider Edge: ISP, PSTN, Frame Relay/ATM.

7. There are two methods of implementing network change: ad hoc method and structured method.

The 4-medium model used in the 8.IT service lifecycle: Cisco Lifecycle Services (PPDIOO), ITIL, Fcaps, and TMN.

9. Develop an implementation plan, which is part of the network design phase, which includes the following:

A. Network information

B. Tools in Need

C. Resources required

D. Implementation of the mandate

E. Verification tasks

F. Performance measurements and results

10. Network convergence completed, that is, all routers in the Network routing table synchronization and packets to all destination network routing. Convergence time refers to the amount of time that all routers in the network agree on a new topology.

11. Characteristics and configuration of static routing (router ODR using Global configuration Command), which uses CDP to transfer network information between a branch (distal) router and a central router.

12. The characteristics of the dynamic routing protocol are as follows:

A. Measure: The routing protocol is used to measure the value of the path to the destination.

B. Configuration: Use global configuration Command router protocol.

C. Distance vector routing: All routers periodically send a routing table (or part of a routing table) to a neighboring router.

D. Link state routing: Each router sends a changed state to all other routers in all other routers or parts of the network (this is called a zone) whenever the state of its interface (link) changes.

E. Advanced distance Vector routing: The protocol sends only changed information (similar to link state information) and only sends that information to a neighboring router (this is similar to the distance vector routing protocol).

F. There are class routing protocol updates: No subnet masks are included. A class protocol (with RIPV1) does not support VLSM and disconnected subnets and must be automatically rolled up to the category address at the network boundary.

G. No class Routing protocol update: contains the subnet mask. Non-class routes (such as RIPv2, EIGRP, and OSPF) support VLSM and disconnected subnets and do not have to be automatically aggregated for network boundaries.

The features and configuration of the 13.RIPV1 and RIPv2 are as follows:

A. Global configuration command router rip enable RIP

B. To accept and send only the groupings of a RIP version, use the Router configuration command version {1|2}.

C. Router configuration commands network Network-number to enable RIP on the pretext of the specified network, and to advertise the network to which these interfaces are connected.

D. Interface configuration command IP RIP {send | receive} version {1 | 2 | 1 2} controls the RIP version used by each interface.

E. Router configuration command No auto-summary turn off automatic Rollup.

F. Interface configuration command IP summary-address RIP network-number mask Specify the network number and subnet mask to meet specific rollup requirements.

The guidelines that are based on the 14.CISCO Router Shim routing table are as follows:

A. Valid next hop IP address: The router first checks to see if the next hop IP address for the route is valid.

B. Measures: If the next hop is valid, the routing protocol selects the best path to the given parent's location, and provides it to the routing table, according to the principle of minimum measure value.

C. Management distance: If you know from different routing sources that multiple routes to the same network (their prefixes are the same), the router will decide which route to add to the routing table based on the management distance of the routing source. Management distance is a value of 0-255, the smaller the management distance, the higher the credibility of the Protocol. The least managed route Jiangbei is added to the routing table, while other routes are rejected.

F. Prefix: Router to view the prefix of the advertisement. In the routing table, you can have routes that go to the same network but have different prefixes.

15. Compare various IP routing protocols. In an enterprise composite network module, multiple protocols may be used. In a corporate network, it is recommended that you use EIGRP and OSPF. When you connect an autonomous system over the Internet, you must use BGP.
