【正文】 設(shè)計(jì)。局域網(wǎng)內(nèi)的主機(jī)將自己的缺省路由下一跳設(shè)置為該虛擬路由器的IP地址。 Command Purpose Step 1 interface interfaceid Enter interface configuration mode, and enter the Layer 3 interface on which you want to enable HSRP. Step 3 it can be learned on the other interfaces. ? (Optional) secondary—The IP address is a secondary hot standby router interface. If neither router is designated as a secondary or standby router and no priorities are set, the primary IP addresses are pared and the higher IP address is the active router, with the next highest as the standby router. Step 4 show standby [interfaceid [group]] Verify the configuration. Step 6 configure terminal Enter global configuration mode. Step 2 standby [groupnumber] priority priority [preempt [delay delay]] Set a priority value used in choosing the active router. The range is 1 to 255。 standby [groupnumber] [priority priority] preempt [delay delay] Configure the router to preempt, which means that when the local router has a higher priority than the active router, it assumes control as the active router. ? (Optional) groupnumber—The group number to which the mand applies. ? (Optional) priority—Enter to set or change the group priority. The range is 1 to 255。 standby [groupnumber] track type number [interfacepriority] Configure an interface to track other interfaces so that if one of the other interfaces goes down, the device39。 第6章靜態(tài)路由靜態(tài)路由是一種特殊的路由,它由管理員手工配置而成?!維witch相關(guān)配置】Switch configure terminal Enter configuration mands, one per line.如果在300秒之內(nèi)收不到從某一網(wǎng)上鄰居發(fā)來(lái)的路由刷新報(bào)文,則將該網(wǎng)上鄰居的路由從路由表中清除。為限制收斂時(shí)間,RIP規(guī)定metric取值0~15之間的整數(shù),大于或等于16的跳數(shù)被定義為。RIP使用跳數(shù)(Hop Count)來(lái)衡量到達(dá)信宿機(jī)的距離,稱為路由權(quán)(Routing Metric)。RIP路由RIP是一種基于距離矢量(DistanceVector)算法的協(xié)議,它使用UDP報(bào)文進(jìn)行路由信息的交換。End with CNTL/Z.Switch(config) ip routing Switch(config)ip route next-network next-address舉例:Switch(config)ip route 在組網(wǎng)結(jié)構(gòu)比較簡(jiǎn)單的網(wǎng)絡(luò)中,只需配置靜態(tài)路由就可以實(shí)現(xiàn)網(wǎng)絡(luò)互連,仔細(xì)設(shè)置和使用靜態(tài)路由可以防止路由振蕩,缺點(diǎn)是有可能會(huì)產(chǎn)生路由黑洞。路由協(xié)議配置優(yōu)先級(jí)0為系統(tǒng)保留給特殊用途來(lái)使用,255則是系統(tǒng)保留給IP地址擁有者。 the default is 0 (no delay before taking over). Use the no form of the mand to restore the default values. Step 5 the default is 0 (no delay before taking over). Use the no form of the mand to restore the default values. Step 4 Enter interface configuration mode, and enter the HSRP interface on which you want to set priority. Step 3 interface interfaceid Purpose Step 1 Command (Optional) Save your entries in the configuration file. copy runningconfig startupconfig Return to privileged EXEC mode. Step 5 end Create (or enable) the HSRP group using its number and virtual IP address. ? (Optional) groupnumber—The group number on the interface for which HSRP is being enabled. The range is 0 to 255。 standby [groupnumber] ip [ipaddress [secondary]] Enter global configuration mode. Step 2 configure terminal 當(dāng)備份組內(nèi)的Master交換機(jī)不能正常工作時(shí),備份組內(nèi)的其它Backup交換機(jī)將接替不能正常工作的Master交換機(jī)成為新的Master交換機(jī),繼續(xù)向網(wǎng)絡(luò)內(nèi)的主機(jī)提供路由服務(wù),從而實(shí)現(xiàn)網(wǎng)絡(luò)內(nèi)的主機(jī)不間斷地與外部網(wǎng)絡(luò)進(jìn)行通信。虛擬的交換機(jī)擁有自己的真實(shí)IP地址(這個(gè)IP地址可以和備份組內(nèi)的某個(gè)交換機(jī)的接口地址相同),備份組內(nèi)的交換機(jī)也有自己的IP地址。交換機(jī)HSRP配置『兩臺(tái)交換機(jī)主備的配置流程』通常一個(gè)網(wǎng)絡(luò)內(nèi)的所有主機(jī)都設(shè)置一條缺省路由,主機(jī)發(fā)往外部網(wǎng)絡(luò)的報(bào)文將通過(guò)缺省路由發(fā)往該網(wǎng)關(guān)設(shè)備,從而實(shí)現(xiàn)了主機(jī)與外部網(wǎng)絡(luò)的通信。核心交換機(jī)將vlan做為一種接口對(duì)待,就象路由器上的一樣,如下所示: switch(config)interface vlan 10 switch (configif)ip address VLAN10接口IP switch (config)interface vlan 11 switch (configif)ip address VLAN11接口IP switch (config)interface vlan 12 switch (configif)ip address VLAN12接口IP再在各接入VLAN的計(jì)算機(jī)上設(shè)置與所屬VLAN的網(wǎng)絡(luò)地址一致的IP地址,并且把默認(rèn)網(wǎng)關(guān)設(shè)置為該VLAN的接口地址。給VLAN分配IP地址分兩種情況,其一,給VLAN所有的節(jié)點(diǎn)分配靜態(tài)IP地址;其二,給VLAN所有的節(jié)點(diǎn)分配動(dòng)態(tài)IP地址。配置VTP DOMAINVTP DOMAIN 稱為管理域。 驗(yàn)證VLAN配置情況.Step 7 show interfaces interfaceid switchport remove關(guān)健字Step 5 配置二層口為trunkStep 4 switchport mode trunk 進(jìn)入配置狀態(tài)Step 2 configure terminal 保存配置使用 default interface interfaceid 還原到缺省配置狀態(tài)。 copy runningconfig startupconfig 驗(yàn)證端口的VLAN號(hào)Step 7 show runningconfig interface interfaceid 把端口分配給某一VLANStep 5 switchport access vlan vlanid 進(jìn)入要分配的端口Step 3 interface interfaceid 目的 Step 1 命令 將端口分配給一個(gè)VLAN 注意 保存配置(可選)舉例如下:Switch vlan databaseSwitch(vlan) vlan 20 name test20Switch(vlan) exitAPPLY pleted.Exiting....Switch copy runningconfig startup config 更新VLAN數(shù)據(jù)庫(kù)并退出Step 5 exit 加入VLAN號(hào)及VLAN名Step 3 vlan vlanid name vlanname 目的 Step 1 命令 (可選) 保存配置用no vlan name 或 no vlan mtu 退回到缺省的vlan配置狀態(tài)舉例如下:Switch configure terminalSwitch(config) vlan 20Switch(configvlan) name test20Switch(configvlan) end也可以在VLAN狀態(tài)下,進(jìn)行VLAN配置: copy runningconfig startup config 退出Step 6 end (可選)輸入一個(gè)VLAN名,如果沒有配置VLAN名,缺省的名字是VLAN號(hào)前面用0填滿的4位數(shù),如VLAN0004是VLAN4的缺省名字Step 4 name vlanname 配置正常范圍的VLANVLAN號(hào)1, 1002到1005是自動(dòng)生成的不能被去掉。 交換機(jī)必須配置成VTP透明模式當(dāng)需要生成VLAN 號(hào)從1006到4094. 本交換機(jī)支持基于每一VLAN的生成樹(PVST),最多支持128個(gè)生成樹。簡(jiǎn)介VLAN(Virtual Local Area Network),是一種通過(guò)將局域網(wǎng)內(nèi)的設(shè)備邏輯地而不是物理地劃分成一個(gè)個(gè)網(wǎng)段從而實(shí)現(xiàn)虛擬工作組的技術(shù)。對(duì)于三層接口,你人工創(chuàng)建該邏輯接口:Figure 331 Typical EtherChannel Configuration 舉例:把交換機(jī)A,B的1,2號(hào)口添加到同一個(gè)組5里面SwitchA configure terminal SwitchA (config) interface range gigabitethernet0/1 2 SwitchA (configifrange) switchport mode accessSwitchA (configifrange) switchport access vlan 10SwitchA (configifrange) channelgroup 5 mode ONSwitch(configifrange) end SwitchB configure terminal SwitchB(config) interface range gigabitethernet0/1 2 SwitchB(configifrange) switchport mode accessSwitchB(configifrange) switchport access vlan 10SwitchB(configifrange) channelgroup 5 mode ONSwitchB(configifrange) end 第4章你可以把多干道端口加到一個(gè)邏輯的干道端口;把多訪問(wèn)端口加到一個(gè)邏輯訪問(wèn)端口;或者多隧道端口加到一個(gè)邏輯的隧道接口。以太通道端口組(Ethernet Port Groups
