[j-nsp] ISIS adjacency on the GigE interface

[Dave McGaugh]

I'm not an ISO expert, but here goes :)
You might try changing the AFI from 99 to 49. Some docs I've read  
seem to suggest that the AFI is, among other things responsible for  
defining the addressing format. I'm not sure whether JunOS enforces  
such a thing, but if your addressing structure conflicts with that  
which is defined for AFI 99, it could create problems..
