DHCP Address Pool Exclusions

You can exclude select IPv4 or IPv6 addresses from a DHCP address pool. Within a configured address pool, you can specifically exclude up to 20 addresses. Junos OS will not assign these excluded addresses to any clients.

Consider the following when you exclude addresses from a DHCP address pool:

• Configure no more than 20 excluded addresses per address pool.
• Excluded addresses must match the address family of the configured address pool. For example, you cannot exclude an IPv4 address within an IPv6 address pool.
• If you configure an excluded address that has already been assigned to a DHCP client, that excluded address will be revoked from the client.To configure an excluded address, include the excluded-address command in the [edit access address assignment-address pool] heirarchy level.
• Use the show network-access address-assignment pool command to see any excluded addresses in the address pool.
• You can also use the show network-access aaa statistics address-assignment pool command to view the number of excluded addresses.
