负载分担――――网络改造

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 //和华为路由连接的接口
description to_hauwei
ip address 172.31.253.42 255.255.255.252
ospf network-type p2p
#
interface GigabitEthernet3/1/0.109 //上行接口
vlan-type dot1q vid 109
ip address 172.31.255.42 255.255.255.252
ospf network-type p2p
#
interface GigabitEthernet3/1/1
description to fw
#
interface GigabitEthernet3/1/1.60 //指向交换的接口
description to fw
vlan-type dot1q vid 60
ip address 172.31.59.1 255.255.255.248
ospf cost 50
#ospf 109 router-id 172.30.1.11
area 0.0.0.109
network 172.30.1.11 0.0.0.0
network 172.31.255.42 0.0.0.0
network 172.31.253.40 0.0.0.3
network 172.31.59.1 0.0.0.0
华为路由配置为：
interface GigabitEthernet3/0/0
description to shangxing //上行接口
port shaping 8 //流量整形，定位8M
#interface GigabitEthernet3/0/1
description to huasan //连接华三路由的接口
undo shutdown
ip address 172.31.253.41 255.255.255.252
ospf network-type p2p //ospf网络类型为点对点
interface GigabitEthernet3/0/2.120
vlan-type dot1q 120
description to FW4120
ip address 172.33.59.1 255.255.255.248
interface LoopBack0
ip address 172.30.2.11 255.255.255.255[/i]

ospf 109

network 172.31.253.41 0.0.0.3 [/i] description sr6608

核心交换简单配置：

interface Vlan-interface60
description to huasan // 到华三路由
ip address 172.31.59.2 255.255.255.248
ospf cost 50
#
interface Vlan-interface120
description to huawei //到华为路由
ip address 172.33.59.2 255.255.255.248
#
interface Vlan-interface300
ip address 172.27.1.1 255.255.255.0
#
interface GigabitEthernet3/0/1
port link-type trunk
undo port trunk permit vlan 1
port trunk permit vlan 60 120
