A company wants to switch from static routing to a dynamic routing protocol to ease the administrative and operational overhead. The network topology is hub and spoke, and the branches use DMVPN back to the hub with two 10-Mbps internet connections. The branch routers are multivendor and have limited memory and CPU resources.
Which routing protocol and design solution meets the requirements?

• A.EIGRP with branch routers as stub routers and variance enabled
• B.eBGP with the hub routers set up as route reflectors
• C.ISIS with the hub and spoke routers configured in two different areas
• D.OSPF with the hub in area 0 and branch routers in stub areas with ECMP

• A.Campus: 10.0.0.0/20
  Branch1: 10.0.64.0/21
  Branch2: 10.0.128.0/21
• B.Campus: 10.0.0.0/10
  Branch1: 10.64.0.0/10
