rib-group for ISIS assistance needed

    I have the following topology:
    There is a GRE tunne between Branch and VRF on vMX1.
    I like to import ISIS routes from vrf into inet.0 on vMX1.
    I have the following :

    root@vMX1# run show route 10.150.99.0/24

    inet.0: 20 destinations, 20 routes (17 active, 0 holddown, 3 hidden)

    Branch1.inet.0: 5 destinations, 5 routes (5 active, 0 holddown, 0 hidden)
    + = Active Route, - = Last Active, * = Both

    10.150.99.0/24 *[IS-IS/165] 00:54:56, metric 20
    > to 173.18.99.1 via gr-0/0/10.0

    set routing-options rib-groups ISP1-to-inet import-rib Branch1.inet.0
    set routing-options rib-groups ISP1-to-inet import-rib inet.0

    I can't see the rib-group I configured when I ran the following:
    root@vMX1# set routing-instances Branch1 protocols isis rib-group ?
    Possible completions:
    + apply-groups Groups from which to inherit configuration data
    + apply-groups-except Don't inherit configuration data from these groups
    inet Name of the IPv4 routing table group
    inet6 Name of the IPv6 routing table group
    [edit]

    But it shows the rib-group when I ran the following:

    root@vMX1# set routing-instances Branch1 protocols ospf rib-group ?
    Possible completions:
    <rib-group> Routing table group for importing OSPF routes
    ISP1-to-inet
    [edit]

    After I added the following configuration to try import ISIS routes from vrf into inet.0, it did not work.

    root@vMX1# set routing-instances Branch1 protocols isis rib-group inet ISP1-to-inet

    [edit]
    root@vMX1# commit
    commit complete

    [edit]
    root@vMX1# run show route 10.150.99.0/24

    inet.0: 20 destinations, 20 routes (17 active, 0 holddown, 3 hidden)

    [edit]
    root@vMX1# delete routing-instances Branch1 protocols isis rib-group inet ISP1-to-inet

    [edit]
    root@vMX1# run show route 10.150.99.0/24

    inet.0: 20 destinations, 20 routes (17 active, 0 holddown, 3 hidden)

    Branch1.inet.0: 5 destinations, 5 routes (5 active, 0 holddown, 0 hidden)
    + = Active Route, - = Last Active, * = Both

    10.150.99.0/24 *[IS-IS/165] 00:00:07, metric 20
    > to 173.18.99.1 via gr-0/0/10.0

    bgp.l3vpn.0: 5 destinations, 5 routes (5 active, 0 holddown, 0 hidden)
    + = Active Route, - = Last Active, * = Both

    192.168.0.1:1:10.150.99.0/24
    *[IS-IS/165] 00:00:07, metric 20
    > to 173.18.99.1 via gr-0/0/10.0

    thanks in advance !!

    sorry to bother.
    I am not patient enough to wait until the ISIS routes showing up in inet.0

    root@vMX1# run show route protocol isis

    inet.0: 20 destinations, 22 routes (18 active, 0 holddown, 3 hidden)
    + = Active Route, - = Last Active, * = Both

    10.150.0.99/32 *[IS-IS/18] 00:00:01, metric 10
    > to 173.18.99.1 via gr-0/0/10.0
    10.150.99.0/24 *[IS-IS/165] 00:00:01, metric 20
    > to 173.18.99.1 via gr-0/0/10.0

    Branch1.inet.0: 4 destinations, 4 routes (4 active, 0 holddown, 0 hidden)
    + = Active Route, - = Last Active, * = Both

    10.150.0.99/32 *[IS-IS/18] 00:00:01, metric 10
    > to 173.18.99.1 via gr-0/0/10.0
