This is of course a subjective >statement, I'd like to hear from more fulltime implementors what their >take on this is. In our case (Cisco NX-OS), the code point was used for the BGP Remote Next Hop attribute (draft-vandevelde-idr-remote-next-hop). When the approach was abandoned, the mistake made was not to remove the attribute handling and validation. Hence, NX-OS switches will not propagate the 31 attribute (assuming validation failure and an optional transitive attribute). As you would guess, this is not something that would show up in normal regression or feature testing since attribute 31 was unallocated. We debated the severity of this problem given NX-OS’s Place In Network (PIN) but decided it was better to disclose the problem. As Jakob already indicated, we are sorry for the oversight.
