[j-nsp] Running OSPF to manage loopbacks, only have trunks

[Morgan McLean]

So for example, if I have a meshed layer 2 network with switches and I would
like to be able to maintain device reachability using something like OSPF,
how would I go about doing this? Everything already had two connections to
its upstream etc, but they are in the form of trunks. Junos won't let me add
a unit when there is already a unit set as ethernet switching and port mode
trunk.

Is there any way I can create an addressable interface just for point to
point ospf neighbor relationships, and maintain my ethernet trunks? What I
don't want to do is run additional cables between everything. I already run
two uplinks from every access switch into my core switches. I don't want to
make a giant vlan and put all the devices loopbacks in it, one for
scalability issues but also for broadcast related issues. I could maybe make
private vlans between each link, but again thats bad because I'll eventually
run out of tags! This is just me getting creative at this point, lol.

Thanks,
Morgan
