allow-bulk-leasequery (DHCP Local Server)
Statement introduced in Junos OS Release 16.1.
Enable a DHCPv4 or DHCPv6 local server to listen for, process, and respond to bulk leasequery requests received on TCP connections on TCP port 67 for DHCPv4 and on TCP port 547 for DHCPv6.
Range: 1 through 10
An empty reply is a response sent from the DHCP local server that contains no bindings or has an option status code error. Empty replies are often the response to an unauthorized requestor that has sent an invalid or incorrect query that produces no binding information. By limiting the number of empty replies that the DHCP local server can send, you prevent the connection from being consumed by an unauthorized or malicious requester, and free up the DHCP local server to support legitimate requestors.
Range: 1 through 100
Restricted requestors are determined as follows:
For DHCPv4 bulk leasequery requests, the giaddr of the requestor must match the giaddr of the client.
For DHCPv6 bulk leasequery requests, the requestor’s client ID in the bulk leasequery message must match the relay ID sent during binding creation.
Range: 1 through 1000
