A host name is easier to remember than a system ID. After enabling this feature on the router, you can see
the host names instead of system IDs using the display command.
BFD
Bidirectional forwarding detection (BFD) provides a single mechanism to quickly detect any link failures
between IS-IS neighbors to reduce network convergence time. For more information about BFD, see High
Availability Configuration Guide.
