CCNP – EIGRP 综合实验
Topology
Objective
-
Implement a topology and EIGRP routing.
Challenge Steps
1. Configure all interfaces in the topology diagram with the IP addresses shown. Configure a bandwidth of 64 on all serial interfaces.
2. Configure EIGRP AS 1 to route all networks shown in the diagram. && Disable auto-summarization.
R1:
router eigrp 1
network 172.16.1.1 0.0.0.0
network 172.16.12.1 0.0.0.0
no auto-summary
R2:
router eigrp 1
network 172.16.2.1 0.0.0.0
network 172.16.12.2 0.0.0.0
network 172.16.23.2 0.0.0.0
no auto-summary
R3:
router eigrp 1
network 172.16.0.0
no auto-summary
R4
router eigrp 1
network 172.16.0.0
no auto-summary
3. Configure R4 to summarize its loopback addresses to the most specific summary possible.
172.16.4.00000001
172.16.4.00100001
172.16.4.01000001
172.16.4.01100001
interface Serial1/2
bandwidth 64
ip address 172.16.34.4 255.255.255.0
ip summary-address eigrp 1 172.16.4.0 255.255.255.128 5
serial restart-delay 0
end
4. Do not multicast EIGRP hellos on the network between R1 and R2.
R1:
router eigrp 1
neighbor 172.16.12.2 Serial1/0
R2:
router eigrp 1
neighbor 172.16.12.2 Serial1/0
5. Modify the hello timers on the link between R2 and R3 to send a hello packet every 2 seconds.
R2:
interface Serial1/1
ip hello-interval eigrp 1 2
R3:
interface Serial1/1
ip hello-interval eigrp 1 2
6. Use MD5 authentication with the key "cisco" over the link between R3 and R4.
R3(config)#key chain EIGRP-KEYS
R3(config-keychain)#key 1
R3(config-keychain)#key-string cisco
R3(config-keychain)#end
R3(config)#interface s1/2
R3(config-if)#ip authentication mode eigrp 1 md5
R3(config-if)#ip authentication key-chain eigrp 1 EIGRP-KEYS
R4(config)#key chain EIGRP-KEYS
R4(config-keychain)#key 1
R4(config-keychain)#key-string cisco
R4(config-keychain)#end
R4(config)#interface s1/2
R4(config-if)#ip authentication mode eigrp 1 md5
R4(config-if)#ip authentication key-chain eigrp 1 EIGRP-KEYS
7. Run a Tcl script on all routers to verify that there is connectivity between the correct routers and IP addresses.
