Release Information
Statement introduced in Junos OS Release 8.3.
Support at the [edit ... dhcpv6] hierarchy levels introduced in Junos OS Release 11.4.
allow-server-change option added in Junos OS Release 16.2R1.
Description
Apply a DHCP relay agent configuration to the named group of DHCP server addresses. The server group itself is configured with the server-group statement. You can apply an active server group globally or for specific groups of interfaces, configured with the group statement. An active server group applied to an interface group overrides a global configuration.
Options
allow-server-change—(Optional) (DHCPv4 only) Enable the relay agent to accept and forward
a DHCP request (renew or rebind) ACK message to the client from any
DHCP local server in the active server group. Starting in Junos OS
Release 18.4R1, this option also applies to DHCP information request
(DHCPINFORM) ACK messages.
Default: Forward ACK messages from only the original binding server.
server-group-name—Name of the group of DHCP or DHCPv6 server addresses
to which the DHCP or DHCPv6 relay agent configuration applies.
Required Privilege Level
interface—To view this statement in the configuration.
interface-control—To add this statement to the configuration.
