When implementing MPLS VPNs between CE and PE routers, which of these statements is correct? As a Network Engineer, it is necessary for you to know how to implement MPLS VPNs between Customer Edge and Provider Edge routers. Refer to the following descriptions, which one is making sense?（）A、If using OSPF or EIGRP as the PE-CE routing protocol, redistribution is not required, but any other protocol or static route will require redistributionB、If using IS-IS as the PE-CE routing protocol, no redistribution is requiredC、If using static routes between the CE and PE routers, no redistribution of other VPN routes is requiredD、If PE-CE protocol is not BGP, redistribution of other VPN routes from MP-BGP is required

Which four statements about the Carrier Supporting Carrier （CSC） feature are true？ （）A、MPLS is required between the PE and CE routers that connect the backbone carrier to the customer carrier.B、The backbone carrier must enable the PE router to check that the packets it receives from the CErouter contain only the labels that the PE router advertised to the CE router.C、Every packet that crosses the backbone carrier must be encapsulated so that the packet includes MPLS labelsD、AII PE routers that link the backbone carrier to the customer carrier must run Route Target Rewrite.E、Arouting protocol is required between the PE and CE routers that connect the backbone carrierto thecustomer carrier. The routing protocol enables the customer carrier to exchange IGP routing information with the backbone carrier.
What does the OSPF command capability vrf-lite achieve？（）A、It enables provider edge （PE） specific checks on a router when the OSPF process is associated with the VRFB、It disables provider edge （PE） specific checks on a router when the OSPF process is associated with the VRFC、It enables the exchange of the "VRF-Lite" capability when the OSPF adjacency is formed.D、It disables the MPLS processing on the OSPF learned routes inside the VRF
