原来是核心交换只和华三路由相连，现根据需要增加一台华为路由做双机。
并使用ospf动态路由协议。
华三简单配置为：
interface LoopBack0
ip address 172.30.1.11 255.255.255.255
#
interface GigabitEthernet3/0/0
ip address 192.168.1.1 255.255.255.0
#
interface GigabitEthernet3/0/1
description to_hauwei
ip address 172.31.253.42 255.255.255.252

#
interface GigabitEthernet3/1/0.109 //上行接口

ip address 172.31.255.42 255.255.255.252
ospf network-type p2p

interface GigabitEthernet3/1/1.60 //指向交换的接口
description to fw

华为路由配置为：
interface GigabitEthernet3/0/0
description to shangxing //上行接口
port shaping 8 //流量×××，定位8M
#interface GigabitEthernet3/0/1
description to huasan //连接华三路由的接口

核心交换简单配置：
interface Vlan-interface60
