You are a systems engineer for your company. Your company has 20，000 users in a large campus environment located in Los Angeles. Each department in the company is located in its own building. Each department has its own IT staff， which is responsible for all network administration within the building.   The company’s network is divided into several IP subnets that are connected to one another by using dedicated routers. Each building on the company’s main campus contains at least one subnet， and possibly up to five subnets. Each building has at least one router. All routers use RIP version 2 （RIPv2） broadcasts.   The company acquires a new business unit located in Denver. The Denver office has 25 users. The network in the Denver office is connected to the network at the main campus by using a leased frame relay connection. The network administrator at the Denver office installs a Windows Server 2003 computer and configures Routing and Remote Access on this server. The network administrator at the Denver office configures this server as a router and implements RIPv2 in Routing and Remote Access.   Later， the Denver administrator reports that his router is not receiving routing table updates from the routers on the main campus network. He must manually add routing entries to the routing table to enable connectivity between the locations. You investigate and discover that the RIPv2 broadcasts are not being received at the Denver office. You also discover that no routing table announcements from the Denver office are being received on the main campus network.  You need to ensure that the network in the Denver office can communicate with the main campus network and can send and receive automatic routing table updates as network conditions change.   What should you do on the router in the Denver office？（）

• A、 Configure the router to use RIPv1 broadcasts.
• B、 Configure the router to use auto-static update mode.
• C、 Add the IP address ranges of the main campus network to the router’s Accept list and Announce list.
• D、 Add the IP addresses of the main campus routers to the router’s Neighbors list.
