[j-nsp] Ugh, another ISIS problem

Hi all,
I am in my lab trying to test out ISIS between a J2320 running 9.5R2.7 and an MRV Optiswitch 9000 and I'm having an incredibly difficult time getting routes to show up in either device. The config is so simple, I'm confused as to why it's not working and thinking there's a bug. The *only* time I was able to get the loopbacks to show up in the devices' respective route tables was when I configured traceoptions for ISIS policy on the 2320 (?!). After I bounced the adjacency, it never worked again. The prefixes are in the databases on both devices. The other odd thing I noticed is that if I configure 'level 2 hello-interval 5' on the 2320, the output of 'show isis interface extensive' on that router shows the hello-interval to be 1.66 seconds and the hold timer to be 5 seconds (another wtf?!). Configs of both devices are below, as well as output of 'show isis database detail'.
Thoughts?
