Hello, all:

Shouldn't the entries in the output of "show isis adjacency" be one-to-one 
relationship with the neighbor entries in "show isis database details"?

Assume r1 peers with r2, r3 and r4 in level 2 (single connection to each 
neighbor)

but in some cases, they are not. I have one router (say r1), it has adjacency 
with r2 (on the output of "show isis adjacency) but the r2 entry doesn't show 
up in the output of "show isis database details".

but on r2 router, i can see r1 entry on both outputs of "show isis adjacency" 
and "show isis database details". also the interfaces are taking traffic 
between r1 and r2. Why is that?
