Refer to exhibits 1 and 2. A company uses a Metro Ethernet (Gigabit Ethernet) dedicated circuit to communicate between users (subnet B) and servers (subnet A) as shown in Exhibit 1. Both routers use OSPF to advertise the subnets. During a weekly management meeting, they realize that the WAN link is oversize. They have been using only 2 Mb/s in the worst-case scenario. So they propose a new, cheaper WAN connection using a 2-Mb/s Frame-Relay point-to-point link to interconnect both sites (Exhibit 2). The Frame Relay service provider informs them that multicast traffic is not allowed to run over the service provider network. Which one of these options is best to enable the company to establish the OSPF neighbor adjacency?()
