    quidway#show run
    now create configuration...
    current configuration
    !
    frame-relay switching
    !
    interface ethernet0
    ip address 10.1.1.1 255.255.0.0
    ip rip version 2 mcast
    !
    interface serial0
    clock-select dteclk1
    encapsulation frame-relay
    frame-relay intf-type dce
    frame-relay interface-dlci 100
    ip address 2.1.1.1 255.0.0.0
    ip rip version 2 mcast
    !
    interface serial1
    encapsulation ppp
    !
    interface serial2
    flowcontrol normal
    async mode dedicated
    encapsulation ppp
    !
    exit
    router rip
    no auto-summary
    neighbor 2.1.1.2
    !
    end
    路由器b的配置為
    quidway#show run
    now create configuration...
    current configuration
    !
    !
    interface ethernet0
    ip address 10.2.1.1 255.255.0.0
    ip rip version 2 mcast
    !
    interface serial0
    encapsulation frame-relay
    ip address 2.1.1.2 255.0.0.0

    如下說法正確的是（ c ）
    a、兩端廣域網(wǎng)可以聯(lián)通，但局域網(wǎng)不可以連通
    b、兩端廣域網(wǎng)不可以連通，但局域網(wǎng)可以連通
    c、廣域網(wǎng)和局域網(wǎng)都可以連通
    d、廣域網(wǎng)和局域網(wǎng)都不能連通
