EIGRP 修改hello時間間隔

                 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

  Authentication mode is not set

  Use unicast

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
