In my configs and example topology, the only traffic that would transit abr2 would be traffic originating/terminating on abr2 (as long as abr1 and it's interfaces were up). Traffic from isis2 to ospf2, for example, would take the isis2->isis1->abr1->ospf1->ospf2 path. This is due to the 'metric

Offlist it was suggested to me that my typology is not very clear. Perhaps a config snippet will help. Essentially, my two "ABRs" have one foot in the OSPF world and the other foot in the IS-IS world. If needed, I could run OSPF directly between the two ABRs. Both ABRs have direct connection

I have an ISIS/OSPF area joining problem that I am trying to solve, wondering if JUNOS policy can help. Let's say that I have a bunch of routers in an IS-IS Level2 domain. I also have a few routers in an OSPF area (area 0.0.0.0). The two "areas" are joined via two Area Border Routers (ABR1 a
