I think this problem stems from the fact that there are two types of ISIS
hello's :
* LAN, and FR physical or multipoint interfaces will send 'LAN' hello's.
* FR. point-to-point interfaces will send serial/point-to-point hello's.
Different type of hello's will not establish adjacencies. You can see this
with "debug isis adj", which also lists the type of hello it sends and
receives.
To get adjacencies between FR multipoint and FR p2p interfaces, use a tunnel
between the two interfaces and running isis over this tunnel.
