上图为某公司网络组网模式。其中R1为核心路由器（网络出口），LSW1,LSW2为汇聚交换机，LSW3,LSW4为接入交换机，R2模拟DHCP Server。请完成以下配置：
1、 配置MSTP （20分）
配置LSW1,LSW2,LSWW3,LSW4都运行MSTP;且要求instance1映射vlan2，instance2映射vlan3，region-name为RG1;并配置LSW3为instance1的主根桥，instance2的备根桥，LSW4为instance2的主根桥，instance1的备根桥。
2、配置VLAN （15分）
所有交换机之间的互连接口都配置为trunk模式。所有trunk接口仅允许除了vlan1之外的所有vlan通过。
在LSW3上配置：
Vlanif2的iP地址为192.168.2.254/24，vlanif3的iP地址为192.168.3.253/24
在LSW4上配置：
Vlanif2的iP地址为192.168.2.253/24，vlanif3的iP地址为192.168.3.254/24
3、配置VRRP （20分）
在vlanif2下配置VRRP VRID 1的Maste 为SW3,Backup为SW4,虚拟IP地址为192.168.2.1；
在vlanif3下配置VRRP VRID 2的Maste 为SW4,Backup为SW3,虚拟IP地址为192.168.3.1；
在两个备份组中，分别配置Master路由器的优先级为120，抢占时延为5S,监视上行GE0/0/1接口来实现主备快速切换功能。
4、配置 DHCP及DHCP Relay（20分）
使能DHCP server的G0/0/0和G0/0/1接口从全局地址池分配地址；配置地址池vlan2，网关为192.168.2.1，网段为192.168.2.0/24,排除192.168.2.254和192.168.2.253，DNS为10.1.12.1；配置地址池vlan3，网关为192.168.3.1，网段为192.168.3.0/24,排除192.168.3.254和192.168.3.253，DNS为10.1.22.1。在DHCP Relay LSW3、LSW4设备上，分别在vlanif2，vlanif3下配置DHCP中继所对应的DHCP服务组。
5、配置 RIP、OSPF （20分）
在AR2,SW1,SW2上配置RIP v2，关闭自动汇总。配置AR1的G0/0/0,G0/0/1,LOOPBACK0,SW1和SW2的使用OSPF,且都属于Area 0
6、配置Import-route（5分）
在LSW3、LSW4上配置路由引入。
配置完成后，要求公司内网任意网络之间都可以通信，PC1和PC2能获得相应的IP地址，能与R1的Loopback0通信，VRRP主备切换后PC能正常通信。
