EIGRP不同自治系统进行通信

实验需求 ： R1 运行 EIGRP100 R3 运行 EIGRP200

          R2 为边界路由器运行 EIGRP 100 和 EIGRP 200

          R1 ping 通 3.3.3 .3 R3 ping 通 1.1.1.1

实验要点 ：在 R2 上进行 EIGRP 重分布

实验步骤 ：

实验结果测试：
r1#ping 3.3.3.3
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 3.3.3.3, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 20/72/152 ms

r3#ping 1.1.1.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 1.1.1.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 36/92/184 ms
