• 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.

第6题：
