本文共 8620 字，大约阅读时间需要 28 分钟。
Objective: Learn to configure a full mesh topology. Lab Equipment: Router 1, Router 2, Router 3, and Router 4 from the eRouters menu Background Reading: Lab Primer Lesson 9: Frame Relay Again, the company’s corporate office is in Dallas and its sales offices are in San Francisco, New York, and Tampa. The sales offices should be able to access all company resources. You want to establish a full mesh topology in which a point-to-point Frame Relay connection links the corporate office to each sales office and links each sales office to every other sales office. The difference between the Frame Relay hub-and-spoke topology and the full mesh topology is that, with a full mesh topology, every sales office has a direct connection to every other sales office and the corporate office. This is a very redundant topology so if one of the connections fails,data can still be transferred to every site by using a different path.
1. First, assign the host names of Dallas, San_Francisco, New_York, and Tampa to Router 1, Router 2, Router 3, and Router 4, respectively.
Dallas:
San_Francisco:
New_York:
Tampa:
2. Now, enter interface configuration mode for the serial 0 interface on Dallas, and set the encapsulation type to Frame Relay. Be sure to enable the interface. Dallas(config)#interface serial 0 Dallas(config-if)#encapsulation frame-relay Dallas(config-if)#no shutdown
3. Next, create a subinterface for the connection between Dallas and the San Francisco sales office. Dallas(config-if)#exit Dallas(config)#interface serial 0.100 point-to-point Dallas(config-subif)#
4. Assign the subinterface the DLCI number for the connection from Dallas to San_Francisco, and configure the subinterface with the appropriate IP address. Remember to enable the subinterface. Dallas(config-subif)#frame-relay interface-dlci 102 Dallas(config-subif)#ip address 172.16.1.1 255.255.255.0 Dallas(config-subif)#no shutdown
5. Create a subinterface for the connection from Dallas to the sales office in New York. Dallas(config-subif)#exit Dallas(config)#interface serial 0.200 point-to-point Dallas(config-subif)#
6. Add the correct DLCI for the connection from Dallas to New_York, and configure the appropriate IP address for the subinterface. Remember to enable the subinterface. Dallas(config-subif)#frame-relay interface-dlci 103 Dallas(config-subif)#ip address 172.16.2.1 255.255.255.0 Dallas(config-subif)#no shutdown
7. Create a subinterface for the connection from Dallas to the sales office in Tampa. Dallas(config-subif)#exit Dallas(config)#interface serial 0.300 point-to-point Dallas(config-subif)#
8. Add the correct DLCI for the connection from Dallas to Tampa, and configure the appropriate IP address for the subinterface. Remember to enable the subinterface. Dallas(config-subif)#frame-relay interface-dlci 104 Dallas(config-subif)#ip address 172.16.3.1 255.255.255.0 Dallas(config-subif)#no shutdown
9. Access the serial 0 interface of San_Francisco, set the encapsulation to Frame Relay, and enable the interface. San_Francisco(config)#interface serial 0 San_Francisco(config-if)#encapsulation frame-relay San_Francisco(config-if)#no shutdown
10. Create the first subinterface for the connection from San_Francisco to the corporate office in Dallas. San_Francisco(config-if)#interface serial 0.100 point-to-point San_Francisco(config-subif)#
11. Add the correct DLCI for the connection from San_Francisco to Dallas, and configure the appropriate IP address for the subinterface. Remember to enable the subinterface. San_Francisco(config-subif)#frame-relay interface-dlci 201 San_Francisco(config-subif)#ip address 172.16.1.2 255.255.255.0 San_Francisco(config-subif)#no shutdown
12. Create a subinterface for the connection from San_Francisco to New_York. San_Francisco(config-subif)#exit San_Francisco(config)#interface serial 0.200 point-to-point
13. Add the correct DLCI value for the connection from San_Francisco to New_York, and configure the appropriate IP address for the subinterface. Remember to enable the subinterface. San_Francisco(config-subif)#frame-relay interface-dlci 203 San_Francisco(config-subif)#ip address 172.16.4.1 255.255.255.0 San_Francisco(config-subif)#no shutdown
14. Create the subinterface for the connection from San_Francisco to Tampa. San_Francisco(config-subif)#exit San_Francisco(config)#interface serial 0.300 point-to-point
15. Add the correct DLCI value for the San_Francisco to Tampa connection, and configure the appropriate IP address for the subinterface. Remember to enable the subinterface. San_Francisco(config-subif)#frame-relay interface-dlci 204 San_Francisco(config-subif)#ip address 172.16.6.1 255.255.255.0 San_Francisco(config-subif)#no shutdown
16. Access the serial 0 interface of New_York, set the encapsulation to Frame Relay, and enable the interface. New_York(config)#interface serial 0 New_York(config-if)#encapsulation frame-relay New_York(config-if)#no shutdown
17. Create the fi rst subinterface for the connection from New_York to the corporate office in Dallas. New_York(config-if)#exit New_York(config)#interface serial 0.100 point-to-point
18. Add the correct DLCI value for the connection from New_York to Dallas, and configure the appropriate IP address for the subinterface. Remember to enable the subinterface. New_York(config-subif)#frame-relay interface-dlci 301 New_York(config-subif)#ip address 172.16.2.2 255.255.255.0 New_York(config-subif)#no shutdown
19. Create the subinterface for the connection from New_York to San_Francisco. New_York(config-subif)#exit New_York(config)#interface serial 0.200 point-to-point
