GLBP协议配置.docx

GLBP有AVG和AVF，AVG负责响应arp请求，AVF负责数据转发。R1配置：R1(config)#inter eth 0/1R1(config-if)#glbp 10 ip 192.168.20.1 R1(config)#endR1#show glbpEthernet0/1 - Group 10State is Standby ----AVG是standby1 state change, last state change 00:00:31Virtual IP address is 192.168.20.1Hello time 3 sec, hold time 10 sec Next hello sent in 1.152 secsRedirect time 600 sec, forwarder time-out 14400 secPreemption disabledActive is 192.168.20.3, priority 200 (expires in 8.776 sec) ----优先级改成200Standby is localPriority 100 (default) ----默认为100Weighting 100 (default 100), thresholds: lower 1, upper 100 ----权重默认为100Load balancing: round-robin ----负载均衡默认为轮询Group members:cc00.0c24.0001 (192.168.20.2) local ----MAC地址是真实的cc00.0d74.0002 (192.168.20.3)There are 2 forwarders (1 active) ----AVFForwarder 1State is ListenMAC address is 0007.b400.0a01 (learnt)Owner ID is cc00.0d74.0002Time to live: 14398.768 sec (maximum 14400 sec)Preemption enabled, min delay 30 secActive is 192.168.20.3 (primary), weighting 100 (expires in 7.380 sec)Forwarder 2State is Active1 state change, last state change 00:00:37MAC address is 0007.b400.0a02 (default)Owner ID is cc00.0c24.0001Preemption enabled, min delay 30 secActive is local, weighting 100R1#show arpProtocol Address Age (min) Hardware Addr Type InterfaceInternet 192.168.20.1 - 0007.b400.0a02 ARPA Ethernet0/1Internet 192.168.20.2 - cc00.0c24.0001 ARPA Ethernet0/1Internet 192.168.20.3 1 cc00.0d74.0002 ARPA Ethernet0/1R1#R2配置：R2(config)#R2(config)#interface eth 0/2R2(config-if)#glbp 10 ip 192.168.20.1R2(config-if)#glbp 10 ?authenticationAuthentication methodforwarderForwarder configurationip Enable group and set virtual IP addressload-balancing Load balancing methodname Redundancy namepreempt Overthrow lower priority designated routerspriorityPriority leveltimers Adjust GLBP timersweighting Gateway weighting and trackingR2(config-if)#glbp 10 priority 200 ----修改优先级为200R2(config-if)#glbp 10 preempt ----配置AVG抢占R2(config-if)#glbp 10 timers 2 8 ----修改hello和hold时间R2(config-if)#glb
