• The global Layer 2 hold-down timer is also configurable at the BFD interface level. Note that configur-

ing the global value with the ip bfd-std l2-hold-timer command does not override the value set for the 
interface using the ip bfd-std interface l2-hold-timer command.

• The global Layer 2 hold-down timer serves as the default value for a BFD interface. The default timer 

value is overridden when a specific value is configured for the interface.
