Activating multiple DHCP relay servers

Here is the procedure to activate multiple DHCP relay servers in multiple interfaces of EX4300.

The second server was not activated when the command #set active-server-group XENDESKTOP was used under #edit forwarding-options dhcp-relay.

dhcp-relay {
         server-group {
                        PROD {
                              192.168.100.35;
                                    }
                        XENDESKTOP {
                              192.168.101.16;
                                                  }
                                }
          active-server-group PROD;
          group PROD {
                        interface irb.101;
                                }
          group XENDESKTOP {
                       interface irb.102;
                                              }
                               }

To activate the second DHCP server, the activation command should be configured under the group and not globally.
# edit forwarding-options dhcp-relay group XENDESKTOP
# set active-server-group XENDESKTOP
So you would be seeing something like

dhcp-relay {
         server-group {
                       PROD {
                           192.168.100.35;
                                   }
                       XENDESKTOP {
                           192.168.101.16;
                                                 }
                                }
          active-server-group PROD;
          group PROD {
                       interface irb.101;
                                }
          group XENDESKTOP {
                       active-server-group XENDESKTOP;
                       interface irb.102;
                                              }
                  }
