    Does anyone know DHCP relay can be supported in the logical system?

     

    https://www.juniper.net/documentation/en_US/junos/topics/concept/dhcp-extended-dhcp-relay-proxy-overview.html

     

    Logical system support—DHCP relay proxy can be configured in a logical system, whereas a non-proxy mode DHCP relay cannot.

     

    in this article, which says DHCP relay does not support in the logical system

    This doc is part of JunOS Subscriber Mgmt (subscribers such as PPPoE/DHCP etc.), in this case DHCP.

    JunOS subscriber mgmt does not support Logical-System yet (unlike "JUNOSe" of juniper e-series" which supported this function)

     

    This basically means you cannot setup dhcp-relay subscriber mgmt features to work in LS.

    However you can setup  "dhcp-relay with forward-only  knob" in which the dhcp relay does not maintain local bindings.

     

    I would suggest you configure a dhcp relay in routing-instance instead of logical-system.
