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
