CCNA Exploration định tuyến giao thức và khái niệm: Định tuyến tĩnh Lab : cơ bản Cấu hình Static Route Cuối cùng, bạn nên tài liệu thực hiện mạng của bạn. Trên mỗi router, bắt đầu ra lệnh sau đây vào một file văn bản (txt) và tiết kiệm để tham khảo trong tương lai. | CCNA Exploration Routing Protocols and Concepts Static Routing Lab Basic Static Route Configuration Finally you should document your network implementation. On each router capture the following command output to a text .txt file and save for future reference. show running-config show ip route show ip interface brief If you need to review the procedures for capturing command output see Lab . Task 13 Clean Up Erase the configurations and reload the routers. Disconnect and store the cabling. For PC hosts that are normally connected to other networks such as the school LAN or to the Internet reconnect the appropriate cabling and restore the TCP IP settings. Task 14 Challenge In the following exercise fill in the blanks to document the process as the ping travels from source to destination. If you need help with this exercise see Section Path Determination and Switching Function. 1. The ICMP process on PC3 formulates a ping request to PC2 and sends the request to the IP process. 2. The IP process on PC3 encapsulates the ping packet with a source IP address of and destination IP address of. 3. PC3 then frames the packet with the source MAC address of indicate device name and the destination MAC address of indicate device name . 4. Next PC3 sends the frame out on the media as an encoded bit stream. 5. R3 receives the bit stream on its interface. Because the destination MAC address matches the receiving interface s MAC address R3 strips off the Ethernet header. 6. R3 looks up the destination network address in its routing table. This destination has a next-hop IP address of. The next-hop IP address is reachable out interface. 7. R3 encapsulates the packet in an HDLC frame and forwards the frame out the correct interface. Because this is a point-to-point link no address is needed. However the address field in the HDLC packet contains the value 0x8F. 8. R2 receives the frame on the interface. Because the frame is HDLC R2 strips off the header and looks up the
