Router R1 sits at an Enterprise branch office, using both the Internet and a leased line to another Enterprise router for its two connectivity options back into the rest of the Enterprise network. The engineer planning for this branch decided to use the leased line for all Enterprise traffic, unless it fails, in which case the Internet connection should be used to pass traffic to the Enterprise.
Which of the following is most likely to be useful on the branch router?（）
A. IPsec tunnel
B. GRE tunnel
C. Floating stati c route
D. An IGP
