QUESTION 460                       
It has become necessary to configure an existing serial interface to accept a second Frame Relay virtual
circuit.Which of the following processes are required to accomplish this task?(choose three)

A  .configure static frame relay map entries for each subinterface network

B  .remove the ip address from the physical interface

C  create the virtual interfaces with the interface command

D  .configure each subinterface with its own IP address
E  .disable split horizon to prevent routing loops between the subinterface networks

F  .encapsulate the physical interface with multipoint PPP


Answer: BCD

这个选择是不是选择AEF?

BCD答案没问题。增加虚链路，用点到点子接口，不需要map，子接口水平分割也不需要禁止，F都出来ppp了，更不靠谱

A,和题目说的基本无关，并没有说道反向arp 的问题 即不存在手工配置映射关系。
E,关闭水平分割不是防止路由环路 而是解决路由不可达的问题。
F,答非所问，至少我没有见过什么multipoint PPP
