[j-nsp] routing instances - ospf - summarization

[n f]

Hi Pavel, 


This would be the best option, as I can also import the static route to OSPF.


Regarding the loop, I'll check if I can keep the import from ospf RI2 to RI1, as I can't summarize the routes I'll learn
from RI2 neighbor routers.

thanks.

This is rather about protocol-independent policies, not OSPF.

You can use a static route like this: set routing-instances RI2
routing-options static route 10.10/16 next-table RI1.inet.0;

But in one direction only, so you can't add a static route in the
backward direction as JUNOS will reject to commit claiming a possible
RI1<->RI2 loop.

Depending on your needs, you can have a static default from the internal
RI to external RI (or master instance) and exported local/OSPF routes
from the internal RI's to external/master RI for the backward connectivity.
