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.

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.
