The password for privileged EXEC mode isclass.注意：用户模式的密码是：cisco 特权模式的密码是：class,Step 1: Connect the Devices.第一步：连接设备 ConnectWestHQS0/0/1 to W-Branch2 S0/0/0.WestHQis the DCE side of the link and is setting the clock rate.连接WestHQ S0/0/1口至W-Branch2的S0/0/0口。WestHQ是DCE设备，并且已设置时钟。 Connect W-Branch2 to an available interface onWSw.连接W-Branch2至WSw上一个可用的端口。Step 2: Configure the Device Basics.第二步：配置设备基本信息Note:Initially, you can only access router W-Branch2 through the console connection onNetAdmin.注意：首先，你只能通过NetAdmin的Console口连接路由器W-Branch2a.Configure the following on W-Branch2: 为W-Branch2配置以下信息Therouter name isWB2.路由器的名字为WB2Theprivileged EXEC mode uses the following encrypted password:class.特权密码为class(是加密码的)Enable Telnet and console line login using the following password:cisco.开启VTY和Console模式，并且设置密码为ciscoConfigure the banner message-of-the-day asAuthorized access only!配置标语信息为: Authorized access only!b.Configure and verify interface addressing on W-Branch2.配置和确认W-Branch2上的接口地址Usingthe Addressing Table, configure and activate all the necessary interfaces on W-Branch2使用地址表配置和开启W-Branch2相应的接口Verify connectivity.确认连接正常。c.Configure the correct IP addresses on WPC2 and W-Branch1.为W-Branch1和WPC2配置正确的IP地址Configure WPC2 with the last IP address in the subnet.将这个子网中的最后一个IP地址分配给WPC2Configure the Fa0/1 interface on W-Branch1 with the last IP address in the subnet.将这个子网中的最后一个IP地址分配给W-Branch1上的F0/1d.Verify connectivity.确认连接正确Step 3: Discover the Network.第三步，发现网络 Explore the network to determine the IP addressing of the serial interfaces thatWestHQshares with W-Branch1 and W-Branch2.探测这个网络并且确定WestHQ分享给 W-Branch1和 W-Branch2的串口地址 Remotely accessWestHQ.Step 4: Configure Static and Default Routing.配置静态和默认路由a.Configure connectivity to the East Region.配置到East Region连接Usingthe next hop address , configure one summary static route onWestHQfor the entire East Region. The summary should include addresses reserved for future expansion. The East Region subnets are listed in the following table:/24在WestHQ配置一个从下面地址表中到EastRegion的总结静态路由，下一跳地址为：East Region Subnets48/3052/3044/30/2528/25/264/2628/2692/2724/2840/30Configure a default route onWestHQto send to the Internet all other traffic for destinations that are not found in theWestHQrouting table. Use the outbound interface argument.在WestHQ上配置一个到Internet的默认路由，使用出口地址。b.Verify static and default routing.确认静态路由和动态路由正确。Step 5: Configure OSPF Routing.配置OSPF。a.Configure OSPF onWestHQ, W-Branch1, and W-Branch2.在WestHQ, W-Branch1, and W-Branch2配置OSPF。Use OSPF process ID 1 and area 0.OSPF进程号为1，区域为0Advertise each subnet individually with its corresponding wildcard mask. OnWestHQ, do not advertise the subnet to the Internet or the subnet to East Region. 宣告每一个单独的网络，不要宣告Internet和EastRegion子网。Disable OSPF updates out interfaces where there are no OSPF neighbors available.在没有启用OSPF的邻居接口禁用OSPF更新。ConfigureWestHQto send the default route to W-Branch1 and W-Branch2 in OSPF updates.在 WestHQ配置将默认路由更新到W-Branch1和 W-Branch2b.Modify the default OSPF operation.修改默认OSPF参数。Configure W-Branch1 to always be the DR by using a priority of100.配置W-Branch1的优先级为100，使其总为DR，Configure W-Branch2 to always be the BDR by using a priority of50.配置W-Branch2的优先给为50，使其成为BDRChange the hello interval to 20 seconds on W-Branch1 and W-Branch2 for the LAN that these two routers share withServerFarm.更改W-Branch1和 W-Branch2hello间隔为20SVerify OSPF neighbor status.确认邻居状态c.Verify that OSPF is fully operational.确认OSPF全部运行。Verify that the routing tables on W-Branch1, W-Branch2, andWestHQcontain all the expected routes.确信在W-Branch1, W-Branch2, WestHQ上的路由表包含所有期望的路由信息。Step 6: Verify Full Connectivity.第6步：确认已完全连接。Although these are not scored, the following connectivity tests should be successful.下面的测试应该是通的。 To test the static route to East Region, successfully ping betweenWestHQand EPC1. 测试静态路由至East Region。WestHQ和 EPC1之间ping是成功的。 To test the OSPF neighbor establishment withServerFarm, successfully ping between WPC1 and Payroll. 测试与ServerFarm建立OSPF邻居，WPC1 和Payroll是能ping成功的。. To test end-to-end connectivity between the East and West Regions, successfully ping between WPC2 and EPC3. 测试East and 和 Regions终端到终端的连接，WPC2 和 EPC3之间是能ping成功
