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？（） static route needs to be added。 floating static route needs to be added。 bgp backdoor command。 ospf backdoor command。

Which are three advantages of PPPoA implementation？ （） NAP and NSP provide secure access to corporate gateways without managing end-to-end PVCs.NAP and NSP use Layer 3 routing，Layer 2 Forwarding，or Layer 2 Tunneling Protocol tunnels.Hence，they can scale their business models for selling wholesale service。 The NSP can oversubscribe by deploying idle and session timeouts using an industry standard RADIUS server for each subscriber。 Only a single session per CPE on one virtual channel （VC).The username and password are configured on the CPE， so all users behind the CPE for that particular VC can access only one set ofservices. Users cannot select different sets of services， although using multiple VCs and establishing different PPP session on different VCs is possible。 If a single IP address is provided to the CPE， and NAT or PAT is implemented，certain applications such as IPTV，which embed IP information in the payload， well not work. Additionally，if an IP subnet feature is used，an IP address also has to be reserved for the CPE。 PPPoA can use the features on the Cisco Service Selection Gateway （SSG）。
