[j-nsp] ISIS Adjacency Problems

[Eric Van Tol]

Hello,
I'm trying to bring up ISIS between a J2350 running 8.5R2.10 and an MRV Optiswitch.  I currently have ISIS running on the J2350 in an IPv6-only capacity.  If I enable it for this new interface and disable IPv6 in the interface config in ISIS, I still see hellos going out with IPv6 capability.  Here's my config:

topologies ipv6-unicast;
interface ge-0/0/1.930 {
    no-ipv4-multicast;
    no-ipv6-unicast;
    no-ipv6-multicast;
    level 1 priority 10;
    level 2 priority 10;
}
interface ge-0/0/2.0 {
    no-unicast-topology;
}
interface lo0.0 {
    passive;
}
user at router# top show interfaces ge-0/0/1.930 
vlan-id 930;
family inet {
    address xxx.xxx.xxx.161/30;
}
family iso;

Traceoptions shows hello packets being sent out:

My adjacency fails with the error 'supported protocols mismatch' on the other side and the J-Series just sits in 'Init' state.  Am I misunderstanding something about disabling IPv6 capability on this one interface?

thanks,
