does that mean the "ip router isis" command under an interface will inject a
route into the isis database depending on the IS-type of the router instead
of the interface circuit-type ?

the neighborship level does not change the level of the routes...
if a route exists in the isis level-2 database of a router and
you define the circuit-type of 1 between 2 routers,
route will still be in the L2 database on both routers and will
not be visible on the neighboring router.(since it is an L1 neighbor)

but you can use
router isis
 redistribute isis ip level-2 into level-1 distribute-list 100

this will make the router gointo the level-1 isis db of the neighboring
router.

Hi,

It seems the subnet still exist in L2 database even I make the interface as
level-1 only. Am I missing anything ?

Below is my configuration :

router isis
 net 49.0042.4444.4444.4444.00
!
interface Ethernet0
 ip address 136.10.40.4 255.255.255.0
 ip router isis
 isis circuit-type level-1 <====================
end
!
interface Serial0.1 point-to-point
 ip address 136.10.24.4 255.255.255.248
 ip router isis
 frame-relay interface-dlci 401
  class FRTS_R4
 isis metric 30 level-2
end

R4#show isis database level-2 verbose

IS-IS Level-2 Link State Database:
LSPID LSP Seq Num LSP Checksum LSP Holdtime ATT/P/OL
R4.00-00 * 0x00000092 0x9996 1186 0/0/0
  Area Address: 49.0042
  NLPID: 0xCC
  Hostname: R4
  IP Address: 136.10.24.4
  Metric: 10 IS R4.01
  Metric: 30 IS R2.00
  Metric: 0 IP-External 136.10.4.0 255.255.255.0
  Metric: 30 IP 136.10.24.0 255.255.255.248
  Metric: 10 IP 136.10.40.0 255.255.255.0 <====================
