单选题You have a router running BGP for the MPLS network and OSPF for the local LAN network at the sales office. A route is being learned from the MPLS network that also exists on the OSPF local network.It is important that the router chooses the local LAN route being learned from the downstream switch running OSPF rather than the upstream BGP neighbor. Also，if the local OSPF route goes away，the BGP route needs to be used. What should be configured to make sure that the router will choose the LAN network as the preferred path？（）A
static route needs to be addedB
floating static route needs to be addedC
bgp backdoor commandD
ospf backdoor command
