城域网PE和CE之间的路由协议以下说法错误的是（）A、PE与客户端路由器CE之间可运行EBGP、Static以及RIPv2等多种路由协议，CE不需要支持MPLSB、采用EBGP协议与客户CE互联时，如客户没有AS号，建议使用私有的AS号，即使用64512~65535之间的AS号C、在客户端路由器CE能够具备EBGP互联的情况，优先使用EBGP实现PE-CE互联D、在客户端路由器CE和PE互联，优先使用OSPF路由协议

When implementing MPLS VPNs between CE and PE routers, which of these statements is correct? （）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.
考题
单选题When EIGRP is used as the PE-CE routing protocol which of these statements is correct?（）A
EIGRP can be used only as the PE-CE routing protocol if the PE and CE routers are in the same ASB
Other EIGRP AS routes are automatically advertised to the CE router and do not require a redistribution configuration command to be configuredC
