Dynamic Hostname

The dynamic hostname exchange extension helps address the usability issues of maintaining IS-IS routers. IS-IS system IDs (which default to the switch MAC address) are not very readable. When the dynamic hostname feature is enabled, learned IS-IS hostnames are used in place of system IDs in log entries where possible. In addition, hostname TLVs appear in the show isis lsdb detail command display.
