补充实验1：dhcp服务器分配网关-路由器的静态路由优先级

1.拓扑图如下

1. RTB配置dhcp服务器
   [RTB]dhcp enable
   [RTB]dhcp server ip-pool 1
   [RTB-dhcp-pool-1]network 10.1.1.0 24
   [RTB-dhcp-pool-1]gateway-list 10.1.1.1
   2.RTA的ip地址使用dhcp动态获取
   [RTA-GigabitEthernet0/0]ip address dhcp-alloc
   [RTA]display interface brief
   Brief information on interfaces in route mode:
   Link: ADM - administratively down; Stby - standby
   Protocol: (s) - spoofing
   Interface Link Protocol Primary IP Description
   GE0/0 UP UP 10.1.1.2
   GE0/1 DOWN DOWN --
   GE0/2 DOWN DOWN --
   GE5/0 DOWN DOWN --
   GE5/1 DOWN DOWN --
   GE6/0 DOWN DOWN --
   GE6/1 DOWN DOWN --
   InLoop0 UP UP(s) --
   NULL0 UP UP(s) --
   REG0 UP -- --
   Ser1/0 DOWN DOWN --
   Ser2/0 DOWN DOWN --
   Ser3/0 DOWN DOWN --
   Ser4/0 DOWN DOWN --
2. RTA的ip路由表
   [H3C]display iP routing-table

Destinations : 13 Routes : 13
