Two empty-configured MSR routers RTA and RTB are interconnected back to back through their respective Serial1 / 0 interfaces. Make the following configurations on the two routers:

Two empty-configured MSR routers RTA and RTB are interconnected back to back through their respective Serial1 / 0 interfaces. Make the following configurations on the two routers:

RTA: skip

[RouterA-Serial1/0] link-protocol fr ietf

[RouterA-Serial1/0] ip address 10.1.1.1 30

[RouterA-Seria11 / 0] fr map ip 10.1.1.2 30

RTB: [RouterB-Serial1/0] link-protocol fr ietf

[RouterB-Serial1/0] interface serial0/0.1

[RouterB-Serial1/0.1] ip address 10.1.1.2 30

[RouterB-Serial1/0.1] fr map ip 10.1.1.1 30

The physical link between the routers is good, so the following statement is correct ______ . (Multiple choices)
A . two routers are not configured DLCI for , in RTA No ping through RTB
B . In the RTA No ping through 10.1.1.2
C . In the RTA on can ping through 10.1.1.2
D . In the above configuration, if only the type of serial interface 0 / 0.1 on RTB is changed to P2MP , then 10.1.1.2 cannot be pinged on RTA
E . In the above configuration, if only the type of serial interface 0 / 0.1 on RTB is changed to P2MP , then 10.1.1.2 can be pinged on RTA
