    Hi folks,

    Just started out with RIP. Was not able to find much info on the following points. Any help is appreciated. I have defined 2 RIP groups, both in the same routing instance:

    root@rip-host-re0# show protocols rip
    group rip-group1 {
        export advertise-routes-through-rip;
        neighbor et-2/0/25:2.0;
    }
    group rip-group2 {
        neighbor et-2/0/25:3.0;
    }

    1. Do we have a command to check RIP routes for each rip group? I believe the RIP routes will get added to the inet.0 table, but how do I verify which rip group does the route belong to? Found a reference to "show route protocol rip group rip-group1" cli command by chatgpt, however I don't see it on my device.
    2. Is it possible to import routes from one group to another. I found 2 possible solutions:
      1. Define a policy and export it from group1
        1. set policy-options policy-statement EXPORT-TO-RIP2 term 1 from protocol rip-group rip-group1
          set policy-options policy-statement EXPORT-TO-RIP2 term 1 then accept
        2. set protocols rip group rip-group1 export EXPORT-TO-RIP2
        3. Won't this just  re-advertise rip-group1 routes again via rip-group1? I don't see any references to rip-group2
      2. Define a polic and import from group 2
        1. set policy-options policy-statement IMPORT-TO-RIP2 term 1 from protocol rip-group rip-group1
        2. set policy-options policy-statement IMPORT-TO-RIP2 term 1 then accept
        3. set protocols rip group rip-group2 import IMPORT-TO-RIP2
        4. Will this be a more appropriate solution?

    Thanks.

    «rip-group rip-group1» is not a protocol :D

    All RIP routes are going to the same inet.0 table (or yourvrf.inet.0).

    Your best option is to add tags to incoming routes, with an inbound policy, by example then acceptthen tag 10001 ; and match both protocol RIP and this tag for outgoing routes to another rip group (your group 2):

    policy-statement rip-group2-export {
        term from-group1-rip {
            from {
                protocol rip;
                tag 10001;
            }
            then {
                accept;
            }
        }
        term default-deny {
            then reject;
        }
    }
