Installing and Configuring a Cisco Router :
Preparing the Cisco router
- Setting up connections. Power. Access and configuration of the console. The passage in privileged mode. Identification of the hardware configuration. Identifying versions. Configuration mode.
General configuration commands
- Last time, host name, password ... Minimum configuration. Ethernet interfaces.
View Controls
- Validation Tests. Ping function. Trace function. Types of access to the router via the console via the network
Protection of access configuration
- Encryption of passwords. Implementation of filters Telnet access. Associating commands to a level password. Access Control List

Configuring Cisco Switch :
Principles of the frame switching.
-Configure topology LANs reliable. Spanning-tree algorithm.
Virtual LANs: VLAN
- Principles and criteria for establishing VLANs. Configuration commands. Benefits of switching. Integration of the switches in a network of routers.

Configure IP routing :
General
- Creation of an interconnection network. Default routing.
static Routing
- Presentation: advantages and disadvantages. Configuring routing tables. Checks LAN to LAN.
Dynamic Routing RIP V2
- Implementation of routing. Distribution tables. Audits. Management of networks and subnets. Using the debug RIP. Incident handling.
OSPF dynamic routing
- Presentation. Without routing area.
Configuration and implementation of OSPF
- The OSPF metric and the consequences of the choices. Incident Response: convergence. Supervision routing.

Configure a Cisco router for WAN:
- Serial PPP leased line. Configuration of the encapsulation.- Serial Frame Relay. Configuring the physical interface. Configuring virtual serial interfaces. Flow definition, CIR for each DLCI.
- The PPP and its security mechanisms. CHAP configuration mode.
Tutorial :
Configuration of the serial interfaces PPP, Frame Relay.Mise implement CHAP. Validation and routing of emergency. Test and debug configurations.Security :
- Public addresses, private addresses- Implementation of the function of translation: NAT / PAT.
- Translation static or dynamic.
- Filter access to a given application.
- Access-list extended.
Operate a Cisco router :
- Recovery of the password on the router and switch.- Erasing configuration: what to do?
- Starting Cisco. The states of the configuration register. Download a new version of software package.
- Backups. Cisco IOS backup via TFTP. Backup configuration on the network. Change outside router configuration. Downloading a new configuration.
- Supervision. Verification software. Change management. Configuration management.
