网络竞赛命令配置总结:

三层结构部署：

Access2-1:

conf t

default-information originate always
--------------------------------------------------


NAT:
 
int f0/4
   ip nat inside
int f0/5
   ip nat inside
int f0/1
   ip nat outside

用命名访问列表：

ip access-list extend acl-out
   permit 172.31.17.0 0.0.252.255 60.6.238.2 0.0.0.31

ip nat pool cnc 60.6.238.2 60.6.238.20 netmask 255.255.255.224
  
ip nat inside  source list acl-out pool cnc overload


-----------------------------------------------------
在三层交换上配置IP地址前需要：no switchport
