    We have SRX240 appliance with VRRP configuration. There are 2 ISP and MPLS link terminated on SRX.

    There is lo0 interface is configured with IP address.

    Now i want to configure 1)  IP on loopback interface and 2) IP for "Office" routing instance(VRF)

    I have added both IP under lo0 interface with unil 120 and unit 150 respectively.

    While i tried commit check, i got an error - You can not create multiple subinterface under lo0


    Could you please suggest me correct configuration to achieve the requirement.


    Thank you..

    Multiple loopbak interface per routing instance is not supported in JunOS. You have two options:

    1. Create multiple loopack interface and assign each of them in different routing instance

    2. Assign multiple IP addresses on the same loopback interface. (eg:- lo0.0)
