Dear Marian,

Welcome to our community. I will try to answer inline.

No, the routes should be added by OOR automatically. If you use "ip 
route", you should be able to see them.
One thing that you have to take care is that MN and  XTRs need to have a 
valid default route associated with the RLOC's interface configured 
before starting OOR. If we don't have this default route, OOR will not 
work. If you have two or more interfaces, then you will need to have one 
default route per interface (you can use different metric per each one)

I attach an example of an OOR testbed. Addresses with 10.0.X.X are in 
the RLOC space and addresses with 192.168.x.x are in the EID space. 
Please, let me know if this fits with your scenario.

Some notes:

  *

    ms.conf : I also added the site 192.168.2.0/24 with more specifics
    -> This will accept more specific prefixes with same authentication
    information. For instance, this site can be used to register 256 MN,
    all of them using the same password

  *

    In the database mapping, I used rloc-address but it is possible to
    use rloc-iface where we specify the interface of the RLOC  instead
    of the IP address. If a database mapping has more that one rloc, we
    can add here as many as we need.

  *

    In your scenario you don't need to configure PeTRs. They are used to
    interconnect LISP with no LISP sites. We don't have PeTR
    implementation yet.

I hope this will help to have a first contact with OOR. Please, let me 
know if you need more help.

Best regards

Albert
