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 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
