Import-route isis level-2 INTO level-1
This command means that because the level-1-2 to establish and maintain neighbor relationship between the level-1 and level-2, but level 2-routing or introduced from the level-1-2 attached to the transfer, and then level-1-2 issued only a default route in the vertical level-1, so there is need to use *** route, the level- 2 on the exact route is introduced into the level-1, the entire network interworking
