Hello ! 

I have such scheme :

Here I need to ping with 1.1.1.1 from 175.25.75.249 (routing-instances GN) .

I did such connfiguration and it is correct. Pings well.

[edit routing-options]
root# show 
interface-routes {
    rib-group inet MATER->GN-static;
}
static {
    rib-group MATER->GN-static;
    route 1.1.1.0/24 next-hop 192.168.100.254;
}
rib-groups {
    MATER->GN-static {
        import-rib [ inet.0 GN.inet.0 ];
    }
}

 Now I want to repeat this for routing instance GS .

So, I add rib-groups MASTER->GS-static . This entry added to config. But when I add 

set routing-options interface-routes rib-group inet MATER->GS-static

 then previous entry with MASTER->GN disappears

root# show 
interface-routes {
    rib-group inet MASTER->GS-static;
}
static {
    rib-group MATER->GN-static;
    route 1.1.1.0/24 next-hop 192.168.100.254;
}
rib-groups {
    MATER->GN-static {
        import-rib [ inet.0 GN.inet.0 ];
    }
    MASTER->GS-static {
        import-rib [ inet.0 GS.inet.0 ];
    }
}

 Why only one interface route rib-group applicable ???

Hello,

Please try the following and report back:

rib-groups {
    MATER->GN-static {
        import-rib [ inet.0 GN.inet.0 GS.inet.0 ];
    }
}

 HTH

Thanks

Alex

When i do 

rib-groups {
MATER->GN-static {
import-rib [ inet.0 GN.inet.0 GS.inet.0 ];
}
}

 then all routes from GN.inet.0 became known and for GS.inet.0.  ( routes from GN follows to GS). But I want to separate this route tables.

Perhaps , I need  to use import/export specific routes  or use  ..next-table

No, the GN routes should not be injected into GS, only inet.0 interface+static routes will be injected into GN and GS according to Your own config:

[edit routing-options]
root# show 
interface-routes {
    rib-group inet MATER->GN-static;
}
static {
    rib-group MATER->GN-static;
    route 1.1.1.0/24 next-hop 192.168.100.254;
}

  Please post the following printouts:

show route table inet.0 | no-more
show route table GN.inet.0 | no-more
show route table GS.inet.0 | no-more

 HTH

Thanks

Hello,

Thanks for posting the printouts.

I don't see any evidence of routes being leaked from CN.inet.0 into GS.inet.0.

Only routes from inet.0 are leaked to GN.inet.0.

Likewise, only routes from inet.0 are leaked into GS.inet.0.

This is what rib-groups are for:

- leftmost RIB is the "primary" RIB and it is the source of routes

- all other RIBs are "secondary" and are route recipients

- there is no leaking between secondary RIBs in a given RIB group.

You also cross-check the correctness of rib-group operation by doing "show route table <any secondary RIB> extensive" and look for "Primary routing table" and "Secondary tables" fields.

http://www.juniper.net/techpubs/en_US/junos13.2/topics/reference/command-summary/show-route-extensive.html

Only primary RIB must be listed as "Primary routing table".

If You see anything to the contrary, it's a bug.

HTH

Thanks
