关于我国证券经纪业务，下面表述（）是不正确的。

A．路由策略主要由CE路由器控制，使用local-preference控制CE－>PE方向的流量，MED控制PE->CE方向的流量

B．路由策略主要由PE路由器控制，使用local-preference控制PE－CE方向的流量，MED控制CE->PE方向的流量

C．路由策略主要由CE路由器控制，使用local-preference控制PE－>CE方向的流量，MED控制CE->PE方向的流量

D．路由策略主要由PE路由器控制，使用local-preference控制CE－>PE方向的流量，MED控制PE->CE方向的流量

A．对于小客户或者VPN内路由数量少的情况可以采用静态路由

B．对于大客户或对故障收敛时间要求短的客户可以选择OSPF

C．对于大客户或者对路由策略控制要求高的客户采用BGP-4作为PE-CE之间的路由协议

D．对于CE是PC或者server，直接发布直连接口网段到MP-BGP中

A．PE之间MP-BGP

B．PE-CE之间路由协议

C．PE-PE之间IGP

D．PE-PE之间LSP

A. EIGRP can be used only as the PE-CE routing protocol if the PE and CE routers are in the same AS

B. Other EIGRP AS routes are automatically advertised to the CE router and do not require a redistribution configuration command to be configured

C. Unlike other routing protocols that are used between PE and CE routers, EIGRP supports backdoor links

D. Configure of the VPN is only required on the PE router

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. On the CE router, PE neighbors must be configured in the VRF context on the CE router

B. On PE routers, the CE IBGP neighbors are configured in the global BGP configuration

C. On PE routers, the CE EBGP neighbors are configured in the VRF context

D. A separate BGP process must be used on the PE routers for CE routers so that they do not use the same BGP routing process as that used for the PE router‘s other provider neighbors
