五、OSPF 配置
SW1:
#
interface GigabitEthernet1/0/2
port link-mode route
ip address 192.168.100.1 255.255.255.0
#
Ospf 1
Area 0
Network 192.168.100.0 0.0.0.255
Network 192.168.200.0 0.0.0.255
Network 192.168.10.0 0.0.0.255
Network 192.168.20.0 0.0.0.255
Network 192.168.30.0 0.0.0.255
Network 192.168.40.0 0.0.0.255
Network 192.168.50.0 0.0.0.255
R1:
interface Serial1/0
ip address 14.1.1.1 255.255.255.0
interface GigabitEthernet0/0
port link-mode route
ip address 12.1.1.1 255.255.255.0
#

ip address 192.168.80.1 255.255.255.0
#
interface Serial1/0
ip address 14.1.1.2 255.255.255.0
#
Ospf 1
Area 0
Network 192.168.80.0 0.0.0.255
Network 14.1.1.0 0.0.0.255

network 192.168.80.0 mask 255.255.255.0
dns-list 192.168.80.1
六、Telnet 远程配置及console配置
SW1：
telnet server enable
Line vity 0 4
Authentication-mode scheme
local-user aa
Password simple abc1234567
authorization-attribute user-role network-admin
Service-type telnet
Console 配置
Line console 0
Authentication-mode password
Set authentication password simple abc1234567
SW2-10:
telnet server enable
Line vity 0 4
Authentication-mode scheme
local-user aa
Password simple 12345
authorization-attribute user-role network-admin
Service-type telnet
Console 配置
Line console 0
Authentication-mode password
Set authentication password simple 12345
七、ACL 控制列表
控制不同VLAN间不能访问，但都能访问服务器。
Acl num 3000
rule 0 deny ip source 192.168.30.0 0.0.0.255 (7 times matched) 地址不能ping通，也不能访问
rule 5 deny tcp source 192.168.20.0 0.0.0.255 地址能Ping通，但不能访问
packet-filter 3000 outbound 下发控制列表。
查看命令：
dis acl num
只允许200段的IP 远程telnet SW1和其他交换机，其他的ip段不能telnet SW1和其他交换机
rule 0 permit tcp source 192.168.200.20 0 destination-port eq telnet
rule 5 deny tcp destination-port eq telnet
interface Vlan-interface10
packet-filter 3001 inbound
nterface Vlan-interface10
packet-filter 3001 inbound
八、Net 功能 内网通过地址转换访问外网
1. 在核心交换机上做静态路由，指向路由器R1
# ip route-static 0.0.0.0 0 192.168.100.2
2. 在R1 上做静态路由，指向路由器R3和R4
# ip route-static 0.0.0.0 0 12.1.1.2
# ip route-static 0.0.0.0 0 13.1.1.3
3. 路由器R2出口方向建立ip地址
# ip add 12.1.1.1 24
# ip add 13.1.1.1 24
4. R3和R4端口做ospf
R3
#
Int loopback 0
Ip add 7.7.7.7 24
