1.設定ISDN交換機型
RouterA(config)#int bri0
RouterA(config-if)#isdn switch-type basic-ni
RouterB(config)#int bri0

========================設定訊框中繼============================
1.在訊框中繼交換機上,設定主機名稱,frame-relay switching命令,以及每片序列介面的封裝
RouterB(config)#frame-relay switching[makes the router a FR switch]
RouterB(config)#int s0

1.利用encapsulation hdle命令為每片序列介面設定封裝
RouterA(config)#int s0
RouterA(config)#encapsulation hdls
RouterB(config)#int s0

Router(config)#int s0
cencapsulation ppp  //設定PPP封裝
Router(config-if)#^z

Router(config)#access list ?
 <1-99>  IP standard access list
 <100-199> IP extended access list
 <1000-1099> IPX SAP access list
 <1100-1199> Extended 48-bit MAC address access list
 <1200-1299> IPX summary address access list
 <1300-1999> IP standard access list (expanded range)
 <200-299> Protocol type-code access list
 <2000-2699> IP extended access list (expanded range)
 <300-399> DECnet access list
 <400-499> XNS standard access list
 <500-599> XNS extended access list
 <600-699> Appletalk access list
 <700-799> 48-bit MAC address access list
 <800-899> IPX standard access list
 <900-999> IPX extended access list
Router(config)#access-list Access-List-number{permit/deny}source-address〔wildcard mask〕

靜態VLAN
1.設定VLAN名稱
Switch(config)#vlan 2 name sales
Switch(config)#vlan 3 name marketing
Switch(config)#exit
或
Switch(config)#vlan 2
Switch(config-vlan)#name sales
Switch(config-vlan)#vlan 3
Switch(config-valn)#namae marketing
Switch(config-vlan)#^z
P.S. VLAN 1為預設的,不能修改,刪除,或是重新命名

====================== Configuration of OSPF ===========================
Router(config)#router ospf process-id   //識別碼(1-65535)
Router(config-router)#network ip-address mask area area-id

=======================EIGRP passive-interface設置指令=====================
功用:不會傳送Hello訊息和宣告,禁止該介面發言,該介面只能透過其他介面通告給他的鄰居
公式:Router(config-router)#passive-interface interface-port

Router#show ip route

1.備份,還原IOS
  a.檢視IOS版本
   Router#sh version           //檢視router 狀況
