单项选择题Refer to the exhibit. You want to minimize the downtime that results from supervisor engine switchovers on Cisco 6500 Series Switches and Cisco 7600 Series Routers. To achieve this, you are considering deploying a Cisco Nonstop Forwarding with Stateful Switchover solution using OSPF. In the exhibit you can see the output of the show ip ospf neighbor detail command. Which trait of systems using Cisco Nonstop Forwarding with Stateful Switchover and OSPF is shown in the exhibit output and will impact your plan?（）

A. Stateful Switchover for Cisco Nonstop Forwarding only works with BGP.
B. Stateful Switchover for Cisco Nonstop Forwarding must be configured on all adjacent routers.
C. Cisco Nonstop Forwarding with Stateful Switchover helper mode is not supported on the adjacent router.
D. Cisco Nonstop Forwarding with Stateful Switchover helper mode for OSPF has been promiscuousstandardized and is supported on the adjacent router.

多项选择题Refer to the exhibit. Which two of these events will be the result of issuing the above command? （）(Choose two.)

B. The route distinguisher will be used to indicate VPN membership.
C. Extended BGP communities will be used to encode route distinguishers.
D. A 96-bit VPNv4 prefix will be created and propagated across the IP network. 
E. The route distinguisher is 64 bits and will be prepended to an existing IPv4 route to make it globally unique.
