yes, we have only one level. here is the database information from another
router:
--------------------------------------------------------------
[EMAIL PROTECTED]> show isis adjacency
Interface System L State Hold (secs) SNPA
as0.0 m1 2 Up 23
ge-0/0/0.0 r2 2 Up 23
ge-0/3/0.0 r3 2 Up 22
ge-1/0/0.0 r4 2 Up 25
so-3/1/0.0 m2 2 Up 22
[EMAIL PROTECTED]> show isis database level 2 r1.00-00 detail
IS-IS level 2 link-state database:
r1.00-00 Sequence: 0x9c38, Checksum: 0xfa8f, Lifetime: 63949 secs
IS neighbor: r2.00 Metric: 10
IS neighbor: r3.00 Metric: 10
IS neighbor: r4.00 Metric: 10
----------------------------------------------------------------------
though m1 and m2 have adjacencies with r1, but r1's link database doesn't have
m1 and m2 entries.

Yes, if it's all the same level, that should be present and
reported in that level's LSP.

Umm, this is the same LSP number with the same checksum
as above, and both from r1's LSDB, and the same remaining
lifetime, for that matter. Was this perhaps at cut/paste error?
Are you suggesting that in this execution of the command the
"IS neighbor" r2.00 entry didn't exist?

How about a "show isis adjacency" and "show isis database detail"
from both r1 and r2, with raw output. That should illustrate the delta.
