Quản trị mạng Lab 6 - OSPF & EIGRP
CCNA LAB No. 6 : CONFIGURE OSPF & EIGRP Lab time: 1 session Students are recommended to read the entire lab requirement before starting. The TIP session should only be used for troubleshooting. For any problem concerns hardware or losing connectivity, please contact instructor.Caution:• Each student is assigned 2 routers.• Ask your instructor to see how the routers are connected (by serial line of ethernet).Task 1: Basic Configuration1. Access Router x,y through Access Server2. Configure to change the name of Router x,y from router to RouterX, RouterY3. If the routers that you are assigned are connected through WAN interfaces. Identify which interface is DTE or DCE. Set clockrate 64000 on DCE interface. (Make the connection through Ethernet interfaces if the routers that you are assigned don’t have WAN connection. If you cannot ping through Ethernet, ask your instructor to remove any unnecessary VLAN configuration.)4. Configure IP for the Interfaces in the figure above. Check IP connectivity to directly connected networks using ping command Rx(config)#interface serial 1 Rx(config-if)#ip address 150.x.y.x 255.255.255.0 Rx(con-if)#no shutdownTask 2: OSPF single-area 1. Enable OSPF on Router X with process id 1 and Router Y with process id 2 OSPF configuration requires that the OSPF routing process be enabled on the router Router(config)#router ospf process-id With router X : Router(config)#router ospf 1 With router Y: Router(config)#router ospf 22. Network between Rx/Ry and its loopback interfaces should be on OSPF backbone area. Rx(config)#interface loopback 0 Rx(config-if)#ip address 192.x.x.x 255.255.255.255 Rx(config)#router ospf 1 Rx(config-router)#network 150.x.y.0 0.0.0.255 area 0 Rx(config-router)#network 192.x.x.x 0.0.0.0 area 0Task 3: OSPF multi-area 1. Configure OSPF area 1 on interface loopback 0 of router X. Rx(config-router)#network 192.x.x.x 0.0.0.0 area 12. Configure OSPF area 2 on interface loopback 0 of router Y. Ry(config-router)#network 172.y.y.y 0.0.0.0 area 23. Set the OSPF cost associated with the WAN interface to 10. The cost number can be between 1 and 65,535. Use the following interface configuration command to set the link cost Router(config-if)#ip ospf costnumber With R1 R1(config-if)#ip ospf cost 104. Ensure that OSPF hello messages periodically sent out the WAN link every 15 seconds. Router(config-if)#ip ospf hello-interval 15Note : A network administrator is allowed to choose these timer values. A justification that OSPF network performance will be improved is needed prior to changing the timers. These timers must be configured to match those of any neighboring routerIssue Show ip ospf interface serial 1 to view Task 4: EIGRP5. Delete all configuration about OSPF in Task 2 Router(config)#no router ospf <process_id>6. Enable EIGRP on each router in your network using AS 1000. Use the following to enable EIGRP and define the autonomous system: Router(config)#router eigrp autonomous-system-number Exp with router 1 : R1(config)#router eigrp 1000 Indicate which networks belong to the EIGRP autonomous system on the local router by using the following command: Router(config-router)#network network-number 7. Do NOT allow any autosumarization running on these routers. To turn off auto-summarization, use the following command : Router(config-router)#no auto-summary Note : - Automatic summarization may not be the preferred option in certain instances. For example, if there are discontiguous subnetworks auto-summarization must be disabled for routing to work properly - With EIGRP, a summary address can be manually configured by configuring a prefix network. Then the summary address can be defined with the ip summary-address eigrp command Router(config-if)#ip summary-address eigrpautonomous-system-number ip-address mask administrative-distance 8. The EIGRP hello interval should be tuning to 10 seconds R1(config-if)#ip hello-interval eigrp 1000 109.To verify operation of EIGRP ,the commands should be issued : R1#show ip eigrp topology R1#sh ip eigrp neighbors detailEnd of lab 6 . summary-address eigrp command Router(config-if)#ip summary-address eigrpautonomous-system-number ip-address mask administrative-distance 8.
