预配置：略
实验过程
第一步：在R1和R2上配置
R1#debug glbp
GLBP debugging is on
R1#conf t
R1(config)#int f0/0
R1(config-if)#glbp 1 ip 192.168.0.100
R1(config-if)#
Dec 14 19:41:19.351: GLBP: Fa0/0 1 Disabled: a/GLBP IP address configured
Dec 14 19:41:19.355: GLBP: Fa0/0 1 Disabled -> Init
R1(config-if)#
Dec 14 19:41:29.359: GLBP: Fa0/0 Interface up
Dec 14 19:41:29.359: GLBP: Fa0/0 1 Init: d/GLBP enabled
Dec 14 19:41:29.359: GLBP: Fa0/0 1 Init -> Listen
R1(config-if)#
Dec 14 19:41:39.359: GLBP: Fa0/0 1 Listen: g/Active timer expired (unknown)
Dec 14 19:41:39.359: GLBP: Fa0/0 1 Listen -> Speak
Dec 14 19:41:49.359: GLBP: Fa0/0 1 Speak: f/Standby timer expired (unknown)
Dec 14 19:41:49.359: GLBP: Fa0/0 1 Standby router is local
Dec 14 19:41:49.359: GLBP: Fa0/0 1 Speak -> Standby
Dec 14 19:41:49.363: GLBP: Fa0/0 1 Standby: g/Active timer expired (unknown)
Dec 14 19:41:49.363: GLBP: Fa0/0 1 Active router IP is local
Dec 14 19:41:49.363: GLBP: Fa0/0 1 Standby router is unknown, was local
Dec 14 19:41:49.363: GLBP: Fa0/0 1 Standby -> Active
//现在R1成为了glpb的active路由器
R1#sh glbp
//查看glpb运行情况
FastEthernet0/0 - Group 1

第二步：在R2上配置GLBP协议
R2(config)#int f0/0
R2(config-if)#glbp 1 ip 192.168.0.100
R2#sh glbp
FastEthernet0/0 - Group 1
State is Standby]
//R2为standby状态
1 state change, last state change 00:01:36
Virtual IP address is 192.168.0.100
Hello time 3 sec, hold time 10 sec
Next hello sent in 2.948 secs
Redirect time 600 sec, forwarder time-out 14400 sec
Preemption disabled
Active is 192.168.0.1, priority 100 (expires in 9.056 sec)
Standby is local
Priority 100 (default)
Weighting 100 (default 100), thresholds: lower 1, upper 100
Load balancing: round-robin
There are 2 forwarders (1 active)
//现在有2个转发
Forwarder 1
State is Listen
MAC address is 0007.b400.0101 (learnt)
Owner ID is ca91.0354.0000
Time to live: 14399.056 sec (maximum 14400 sec)
Preemption enabled, min delay 30 sec
Active is 192.168.0.1 (primary), weighting 100 (expires in 9.056 sec)
Forwarder 2
State is Active
//转发2现在是激活状态
1 state change, last state change 00:01:41
MAC address is 0007.b400.0102 (default)
Owner ID is ca92.0d30.0000
Preemption enabled, min delay 30 sec
Active is local, weighting 100
第三步：在R3和R4上做测试
R3#ping 192.168.0.100
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.0.100, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 8/222/1052 ms
R3#sh arp
Protocol Address Age (min) Hardware Addr Type Interface
Internet 192.168.0.100 1 0007.b400.0101 ARPA FastEthernet0/0
Internet 192.168.0.3 - ca93.09e0.0000 ARPA FastEthernet0/0
R4#sh arp
Protocol Address Age (min) Hardware Addr Type Interface
Internet 192.168.0.100 0 0007.b400.0102 ARPA FastEthernet0/0
Internet 192.168.0.4 - ca94.0834.0000 ARPA FastEthernet0/0
第四步：最后测试，在R3和R4上ping，在R1上关闭f0/0接口
R3#ping 192.168.0.100 re 1000000
Type escape sequence to abort.
Sending 1000000, 100-byte ICMP Echos to 192.168.0.100, timeout is 2 seconds:
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!......!!!!!!!!!!!!!!!!!!!!!!!!!!!
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
R4#ping 192.168.0.100 re 1000000
Type escape sequence to abort.
Sending 1000000, 100-byte ICMP Echos to 192.168.0.100, timeout is 2 seconds:
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
