What actually may be happening here is that adj. comes up fast and at this point your router does not yet have the dynamic name. After some time it receives it from the neighbor via flooding in TLV 137 and then creates a mapping hence in subsequent commands you see the name. Works as designed :) Flooding that TLV may take a bit of time as well as your local system may not treat it as top important info. Ref: Original Henk's RFC 2763 later replaced by RFC 5301 Best, R.
