EIGRP 修改hello时间间隔

                 大于T1链路时hello的时间间隔默认为5秒

修改间隔的命令为：

interface s0/0

 ip hello-interval eigrp 1 2   其中1为自治域系统号，2为hello时间间隔

 ip hold-time eigrp 1 6，其中1为自治域系统号，6为保持计时器时间

查看修改后的配置

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

实验配置

按照上图配置好借口地址与EIGRP

1.0.0.1 --> 2.0.0.2  是通过fram-relay网络传输，

我们可以做如下测试将R2的s0/0接口手动shutdown后，1.0.0.1 --> 2.0.0.2 多长时间能通

测试方法

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后5秒内 1.0.0.1 -->2.0.0.2 能够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为EIGRP的自治域系统号
