由RIP的等價負載均衡想到的......

一直在練習EIGRP、OSPF協議，今天沒事做做RIP，卻發現了一個大問題！具體問題如下：
按照上圖做好基礎配置，測試時發現：
R1#ping 23.1.1.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 23.1.1.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 16/57/152 ms
R1#
*Mar 1 00:12:55.019: ICMP: echo reply rcvd, src 23.1.1.2, dst 13.1.1.1
*Mar 1 00:12:55.087: ICMP: echo reply rcvd, src 23.1.1.2, dst 13.1.1.1
*Mar 1 00:12:55.123: ICMP: echo reply rcvd, src 23.1.1.2, dst 13.1.1.1
*Mar 1 00:12:55.139: ICMP: echo reply rcvd, src 23.1.1.2, dst 13.1.1.1
*Mar 1 00:12:55.155: ICMP: echo reply rcvd, src 23.1.1.2, dst 13.1.1.1
並沒有執行負載均衡，這是為什麼呢，開始以為是配置錯誤，檢視配置資訊，發現並無錯誤，於是想到，是不是模擬器出錯了，OK!~重新啟動,可問題依舊存在......
1.基於每個分組的負載均衡----程序交換
2.基於每個目的的負載均衡----快速交換
R1#conf t
Enter configuration commands, one per line. End with CNTL/Z.
R1(config)#no ip cef （關閉快速交換）
R1(config)#do ping 23.1.1.2 Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 23.1.1.2, timeout is 2 seconds:
Success rate is 100 percent (5/5), round-trip min/avg/max = 20/59/104 ms
R1(config)#
*Mar 1 00:21:03.799: ICMP: echo reply rcvd, src 23.1.1.2, dst 12.1.1.1
*Mar 1 00:21:03.903: ICMP: echo reply rcvd, src 23.1.1.2, dst 13.1.1.1
*Mar 1 00:21:03.927: ICMP: echo reply rcvd, src 23.1.1.2, dst 12.1.1.1
*Mar 1 00:21:04.019: ICMP: echo reply rcvd, src 23.1.1.2, dst 13.1.1.1
*Mar 1 00:21:04.039: ICMP: echo reply rcvd, src 23.1.1.2, dst 12.1.1.1 實現了負載均衡
