[c-nsp] IS-IS on L3 vlan interfaces

[Walter Keen]

NET addresses for all of these are 
 net 49.0001.0000.0000.0081.00
replace .0081. with
0081 - cent-core
0083 - sea-core
0083 - of-core

I'm sure it's something simple I'm overlooking.

If I set isis network point-to-point on two of these 3, then I instantly get a L1L2 adjacency on those two.  I want a L1L2 adjancency on all 3  (preferably without creating point to point vlans)

Do you have some configurations you can share of the three 
devices?

Cheers,
