In BGP MPLS VPNs, which router maintains VPN-specific routing tables, also known as VRFs？（）

t？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 redistribution

B. If using IS-IS as the PE-CE routing protocol, no redistribution is required

C. If using static routes between the CE and PE routers, no redistribution of other VPN routes is required

D. If PE-CE protocol is not BGP, redistribution of other VPN routes from MP-BGP is required

A. If using IS-IS as the PE-CE routing protocol, no redistribution is required.

B. If using static routes between the CE and PE routers, no redistribution of other VPN routes is required.

C. If the PE-CE protocol is not BGP, redistribution of other VPN routes from MP-BGP is required.

D. If RIP is the routing protocol that is used between the PE-CE routers, no redistribution is required, but any other protocol will require redistribution.

E. If using OSPF or EIGRP as the PE-CE routing protocol, redistribution is not required, but any other protocol or static route will require redistribution.

A. Layer 3 MPLS VPNs can forward only IP packets

B. Layer 2 MPLS VPNs can forward any network protocol

C. MPLS label paths are automatically formed based on Layer 2 frames

D. Layer 3 MPLS VPNs can forward any network protocol based on Layer 2 frames

E. In Layer 2 MPLS VPNS, the service provider controls the customer Layer 3 policies

A. Routing

B. MPLS VPNs

C. Access control

D. Intrusion detection

A. to create a partial mesh of VPN sites

B. to remove MPLS from VPNs

C. to create a point to multipoint topology

D. to enable IPsec accross the VPN

A. Service provider has routing control.

B. Customers control their own routing.

C. Can communicate protocols other than IP.

D. Allows them to use separate networks for IP and VPN traffic.
