Cisco筆記6-靜態路由的負載均衡

實驗拓撲以下：

R2 Loopback  :2.2.2.2

R3 Loopback :3.3.3.3

配置以下：

(1)各路由器ip地址

R1#c
Interface                  IP-Address      OK? Method Status                Protocol
FastEthernet0/0            192.168.1.1     YES NVRAM  up                    up     
FastEthernet0/1            192.168.2.1     YES NVRAM  up                    up     

R2#C
Interface                  IP-Address      OK? Method Status                Protocol
FastEthernet0/0            192.168.3.1     YES NVRAM  up                    up     
FastEthernet0/1            192.168.1.2     YES NVRAM  up                    up     
Loopback0                  2.2.2.2         YES NVRAM  up                    up     

R3#C
Interface                  IP-Address      OK? Method Status                Protocol
FastEthernet0/0            192.168.3.2     YES NVRAM  up                    up     
FastEthernet0/1            192.168.2.2     YES NVRAM  up                    up     
Loopback0                  3.3.3.3         YES NVRAM  up                    up     

（2）配置靜態路由

R1

ip route 2.2.2.0 255.255.255.0 192.168.1.2
ip route 3.3.3.0 255.255.255.0 192.168.2.2

R2

ip route 3.3.3.0 255.255.255.0 192.168.3.2
ip route 3.3.3.0 255.255.255.0 192.168.1.1

R3

ip route 2.2.2.0 255.255.255.0 192.168.2.1
ip route 2.2.2.0 255.255.255.0 192.168.3.1

（3）測試

打開R2上的debug ip packet，用擴展ping來看報的send和receive狀況便可是否實現了負載

R2#ping
Protocol [ip]:
Target IP address: 3.3.3.3
Repeat count [5]:
Datagram size [100]:
Timeout in seconds [2]:
Extended commands [n]: y
Source address or interface: 2.2.2.2
Type of service [0]:
Set DF bit in IP header? [no]:
Validate reply data? [no]:
Data pattern [0xABCD]:
Loose, Strict, Record, Timestamp, Verbose[none]:
Sweep range of sizes [n]:
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 = 4/12/16 ms
R2#
00:10:17: IP: s=2.2.2.2 (local), d=3.3.3.3 (FastEthernet0/1), len 100, sending
00:10:17: IP: s=3.3.3.3 (FastEthernet0/0), d=2.2.2.2, len 100, rcvd 4

00:10:17: IP: s=3.3.3.3 (FastEthernet0/1), d=2.2.2.2, len 100, rcvd 4
00:10:17: IP: s=2.2.2.2 (local), d=3.3.3.3 (FastEthernet0/1), len 100, sending
00:10:17: IP: s=3.3.3.3 (FastEthernet0/0), d=2.2.2.2, len 100, rcvd 4

R3上同理，這裏就不貼出來了。要全通只需在各路由器上加到未知網段的靜態路由便可，寫的比較粗糙只寫出了主要的步驟，嘿嘿！！！
