question about gre tunnel interface with routing-instance destination

  • 1.  question about gre tunnel interface with routing-instance destination

    I came across with a couple of gre tunnel interface configuration sample with routing-instance destination option.
    I do not quite sure when I need to add this.
    Here is a post which is a little different from what I saw too.

    https://kb.juniper.net/InfoCenter/index?page=content&id=KB32683&actp=METADATA

    set interfaces gr-0/0/0 unit 0 tunnel source 192.168.100.1
    set interfaces gr-0/0/0 unit 0 tunnel destination 192.168.200.1/32
    set interfaces gr-0/0/0 unit 0 tunnel routing-instance destination INST2
    set interfaces gr-0/0/0 unit 0 family inet address 10.10.10.1/30

    Here the INST2 refers to the remote instance. When I tried this,  I got  "destination routing instance (INST2) no defined.

    Anyone can coach me the instance name should be local instance or remote instance ?
    Also I added the local instance, it does not work either. I do not know what I have missed here.

    Also does this work for vrf instance ?

    thanks in advance !!
