1. Connection Methods Back to Back is a Design Digital Content & Contents mall developed by Guild Design Inc.

2. Back to Back Method Configurations: one Router act as DTE and another one act as a DCE. first of all use Router#show Running-Config to see what the serial port full name? if serial port doesnt exist you must add it physically. if exist follow these steps: Router(config)#interface serial0/0/0 Router(config-if)#clock rate 64000 Router(config-if)#BandWidth 64 (Mbps ; too important in routing protocols) Tehran Institute of Technology Course name: Cisco CCNA Instructor: Mansour.nch Senior @ Tehran Institute of Technology Copyright 2014

3. In a different Geography This is Done by CSU/DSU Modem , when we are using communication infrastructure in a country this device configure parameters automatically for the best connectivity, so CSU/DSU modem is the best solution for this scenario.

5. An introduction to Routing Connected scenario In this scenario router connected to the destination directly via own interfaces. Routing Theory Learned scenario in this scenario router didnt connected directly to the destination but can learn destination via other routers nearby.

7. An introduction to Routing Static Routing As an administrator of network you know all details about the infrastructure of network. You Teach to the router how to route! Routing Methods Dynamic Routing In this scenario Learning Process is are Automatically Done bye Router Router Learn Routes from neighbors Tehran Institute of Technology Course name: Cisco CCNA Instructor: Mansour.nch Senior @ Tehran Institute of Technology Copyright 2014

8. Static Routing Example Tehran Institute of Technology Stub network is a Local Network Network address of stub network is different from destination , so simple ping command will fail intentionally. Stub network packets has only one way (just one gateway) to access Internet Left network has internet access Router A act as a Gateway to respond requests from Stub Network Network address of this network is different from B network , So ping command will fail intentionally via one host on network A.

9. Static Routing Example Tehran Institute of Technology The host want to access to www.google.com The respond for host request is not here! , not found on this network !! So the request must get out here to find answer The solution is redirect all traffic from stub network to outside Via Router B , Interface: 172.16.2.1 Course name: Cisco CCNA Instructor: Mansour.nch Senior @ Tehran Institute of Technology Copyright 2014

10. Static Routing Example Tehran Institute of Technology Geography Connection between Routers Via Serial Interface , so redirected traffic will flow @ this line and will accepted by Router A via interface: 172.16.2.2 Course name: Cisco CCNA Instructor: Mansour.nch Senior @ Tehran Institute of Technology Copyright 2014

11. Static Routing Example Tehran Institute of Technology So we need to configure a static route right over here! to tell this router, forward the packets to 172.16.2.1 if the packets destination was Stub Network.
