# ip-addrlabel(8)

protocol address label management

## NAME

ip-addrlabel - protocol address label management

## SYNOPSIS

**ip addrlabel**  { *COMMAND* \|  **help** }

- **label** *NUMBER*

  the label for the prefix. 0xffffffff is reserved.

### ip addrlabel del - delete an address label

delete an address label entry from the kernel. **Arguments:** coincide with the arguments of **ip addrlabel add** but the label is not required.

### ip addrlabel list - list address labels

list the current address label entries in the kernel.

### ip addrlabel flush - flush address labels

flush all address labels in the kernel. This does not restore any default settings.
