2021年华三杯竞赛试题 2021年华三杯竞赛试题一、实验拓扑图二、需求本网络模拟一个大型企业网络，需要使用BGP/MPLS VPN技术来隔离不同的VPN,并使用防火墙来做到防攻击与访问策略。请考生根据以下配置需求在HCL中的设备上进行相关配置。PPP配置路由器R1与路由器R3间为广域网链路，使用PPP协议连通。PPP配置的具体要求如下：使用CHAP协议，并且为单向认证：R1作为认证方，R2作为被认证方：R1上配置本地AAA认证；用户名和密码均为123456。虚拟局域网为了减少广播，需要规划并配置VLAN。具体要求如下：配置合理，链路上不允许不必要的数据流通过。交换机与路由器间的互连物理端口直接使用三层模式互连。交换机(S1、S2、L2SW)间的互连端口链路类型为Trunk类型。根据上述信息及表1-1，在交换机上完成VLAN配置和端口分配。链路聚合在交换机S1和S2上配置链路聚合，要求使用二层静态链路聚合组，并设定组号为1；将接口G0/23与G0/24所在的链路聚合起来。MSTP部署在交换机S1、S2及L2SW上配置MSTP防止二层环路；所配置的参数要求如下：STP中的region-name为2021；其他相关要求见下表：IPv4地址部署VRRP部署在交换机S1、S2配置VRRP以提高可靠性，所配置的参数要求如下：S1作为VLAN10内主机的主用网关，S2作为VLAN20内主的主用网关，且互相备份：VRRP的主用优先级为150，备用优先级为110。IPv4IGP路由部署使用OSPF协议及静态路由互通。具体要求如下：R1、R2、R3之间运行OSPF;OSPF进程号为1，区域0；Router ID为本路由器的Loopback地址；R1与S1、S2之间运行OSPF;OSPF进程号为10，区域0：Router ID为本路由器的Loopback地址；S1、S2中的OSPF不允许将协议报文发送到业务网段中；要求OSPF及静态路由都发布具体网段(OSPF必须精确反掩码匹配)，不允许发布缺省路由；为了管理方便，OSPF需要发布Loopback地址，其中R1需要在OSPF进程1中发布。BGP/MPLS VPN部署各个路由器(R1、R2、R3)之间，以及R2与R4之间运行BGP协议。具体要求如下：R2与R4之间运行EBGP,R2属于AS100,R4属于AS300:R1、R2、R3之间运行IBGP,都属于AS100,并以Loopback地址作为互连的源地址：通过network命令方式生成BGP路由，而不允许通过import命令将IGP路由引入。R3与FW1、FW2之间运行静态VPN路由，并配置具体网段（不允许配置缺省路由）。配置两个VPN,并要求同一VPN内能够互访，不同VPN间不能互访。相关参数要求如下：MPLS的lsr-id使用Loopback地址，并使用LDP协议来进行标签分配。防火墙部署FW1、FW2上配置安全域和安全策略。具体要求如下：FWI、FW2与服务器互联接口处于Trust安全域，与R3接口处于Untrust安全域：FW1上配置地址对象组server1,并定义其主机地址为地址172.0.0.1/32；配置安全策略ap1,规则rule0,允许Untrust域中的客户端可以访问Trust域中目的地址为地址对象server1的所有P流量；FW2上配置地址对象组server2,并定义其主机地址为地址192.0.0.1/32；配置安全策略ap1,规则rule0,允许Untrust域中的客户端可以访问Trust.域中目的地址为地址对象server2的所有P流量；FW1、FW2上应用缺省IPS策略对用户数据报文进行IPS防御。具体要求如下：配置DPI应用profile,命名为sec,应用缺省IPS策略default并指定IPS策略模式为protect;在安全策略ap1上引用该sec;FW1、FW2上配置攻击防范策略。具体要求如下：FW1上配置攻击防范策略ad1,配置针对Sever1地址的SYN flood的攻击防范策略，阈值为2000，动作为丢弃并输出告警日志；在安全域Untrust上应用攻击防范策略ad1。FW2上配置攻击防范策略ad1,配置针对Sever2地址的SYNf1ood的攻击防范策略，阈值为2000，动作为丢弃并输出告警日志；在安全域Untrust上应用攻击防范策略ad1。IPv6部署在交换机S1、S2配置IPv6协议。要求使用OSPFv3协议，进程号为1，区域为0；Router ID与OSPF的Router ID相同。IPv6地址如下表所示：设备与网络管理部署根据表1-5，为网络设备配置主机名。三、实验步骤（一）配置ip地址如果你的拓扑图接口跟我一样那么就可以直接复制下面的命令R1sysname R1 interface gig 0/0 ip a 10.0.0.1 30 interface gig 0/1 ip a 10.0.0.5 30 interface gig 0/2 ip a 100.0.0.1 30 interface serial 1/0 ip a 100.0.0.10 30 interface loopback 0 ip a 9.9.9.1 32R2sysname R2 interface gig 0/0 ip a 100.0.0.2 30 interface gig 0/1 ip a 100.0.0.5 30 interface gig 0/2 ip a 10.0.0.9 30 interface l 0 ip a 9.9.9.2 32 R3sysname R3 interface gig 0/0 ip a 100.0.0.6 30 interface gig 0/1 ip a 10.0.0.13 30 interface gig 0/2 ip a 10.0.0.17 30 interface serial 1/0 ip a 100.0.0.9 30 interface loopback 0 ip a 9.9.9.3 32R4sysname R4 interface gi 0/0 ip a 10.0.0.10 30 interface gig 0/1 ip a 192.0.10.254 24 interface l 0 ip a 9.9.9.105 32S1sysname S1 interface gig 1/0/1 port link-mode route ip a 10.0.0.2 30 quit vlan 10 vlan 20 interface vlan 10 ip a 172.0.10.252 24 interface vlan 20 ip a 172.0.20.252 24 interface l 0 ip a 9.9.9.101 32S2sysname S2 interface gig 1/0/1 port link-mode route ip a 10.0.0.6 30 quit vlan 10 vlan 20 interface vlan 10 ip a 172.0.10.253 24 interface vlan 20 ip a 172.0.20.253 24 interface l 0 ip a 9.9.9.102 32FW1sysname FW1 interface gig 1/0/1 ip a 10.0.0.14 30 interface gig 1/0/0 ip a 172.0.0.254 24 interface l 0 ip a 9.9.9.201 32FW2sysname FW2 interface gig 1/0/1 ip a 10.0.0.18 30 interface gig 1/0/0 ip a 192.0.0.254 24 （二）ppp的配置R1[R1]local-user 123456 class network New local user added.
