Usage Guidelines

• The global operational mode and echo status serves as the default mode and status for a BFD interface.

The default mode and status is overridden when a specific value is configured for the interface.

• Note that configuring the interface mode and echo status using the ip bfd-std interface mode

command does not change the global value configured with the ip bfd-std mode command.

Examples

-> ip bfd-std mode echo-only

-> ip bfd-std mode demand echo enable
