大于T1鍊路時hello的時間間隔預設為5秒
修改間隔的指令為:
interface s0/0
ip hello-interval eigrp 1 2 其中1為自治域系統号,2為hello時間間隔
ip hold-time eigrp 1 6,其中1為自治域系統号,6為保持計時器時間
檢視修改後的配置
R1#show ip eigrp interfaces detail
IP-EIGRP interfaces for process 1
Xmit Queue Mean Pacing Time Multicast Pending
Interface Peers Un/Reliable SRTT Un/Reliable Flow Timer Routes
Se0/0 1 0/0 205 0/15 927 0
Hello interval is 1 sec
Next xmit serial <none>
Un/reliable mcasts: 0/0 Un/reliable ucasts: 2/10
Mcast exceptions: 0 CR packets: 0 ACKs suppressed: 4
Retransmissions sent: 2 Out-of-sequence rcvd: 0

實驗配置
按照上圖配置好借口位址與EIGRP
1.0.0.1 --> 2.0.0.2 是通過fram-relay網絡傳輸,
我們可以做如下測試将R2的s0/0接口手動shutdown後,1.0.0.1 --> 2.0.0.2 多長時間能通
測試方法
R1#ping 2.0.0.2 source loopback 0 repeat 1000 timeout 1
Type escape sequence to abort.
Sending 1000, 100-byte ICMP Echos to 2.0.0.2, timeout is 1 seconds:
Packet sent with a source address of 1.0.0.1
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
!!!!!!!!!!!!!!!...!!!!!!!!!!!!!!!!
要求:如果要求在R2的s0/0接口shutdown後5秒内 1.0.0.1 -->2.0.0.2 能夠ping通
修改方法:在R1和R2的s0/0接口上做如下配置即可
ip hello-interval eigrp 1 1
ip hold-time eigrp 1 3
其中前面的1為EIGRP的自治域系統号
