3. Verify the configuration:

# Display BFD sessions on Router A.

<RouterA> display bfd session

Session Working Under Ctrl Mode:

LD/RD SourceAddr DestAddr State Holdtime Interface

4/7 12.1.1.1 12.1.1.2 Up 2000ms Ethernet1/1

The output shows that the BFD session has been created.

# Display static routes on Router A. The static route to Router B through the Layer 2 switch is

displayed in the output.
