Dynamic host name mapping mechanism
The dynamic host name mapping mechanism provides the mappings between the host names and the
system IDs for the IS-IS routers. The dynamic host name information is announced in the dynamic host
name CLV of an LSP.
This mechanism also provides the mapping between a host name and the DIS of a broadcast network,
which is announced in the dynamic host name TLV of a pseudonode LSP.
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
NOTE:
For more information about BFD, see High Availability Configuration Guide.
Bidirectional forwarding detection (BFD) provides a single mechanism to quickly detect any link failures
between IS-IS neighbors to reduce network convergence time.
