Which router translates the Type 7 LSAs into Type 5 LSAs, according to RFC 1587 (OSPF NSSAOption) in an OSPF NSSA with more than one ABR?() A. The router receiving the route translates the Type 7 LSA into a Type 5 LSA.B. The ABR with the lowest router ID translates all Type 7 LSAs into Type 5 LSAs.C. The ABR with the highest router ID translates all Type 7 LSAs into Type 5 LSAs.D. All ABRs translate the Type 7 LSAs into Type 5 LSAs depending on which one has the lowest cost to the route.

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
