Examice · Accepted Answer

In the given topology, R1 is a Level 1 router in Area 49.0002, and hence it cannot directly reach the Level 1 routers in Area 49.0003 (R4 and R5) across the Level 2 backbone (Area 49.0001). R1 cannot inherently reach R5 without a Level 2 router intervening. Hence, R1 itself will create its own default route that points to R2 because R2 is the L1/L2 router and will propagate a default route to R1.

CD. R1 sees attach bit in Level1 LSP and it installs default route in routing table.
Also i dont see any reason why R1 cant reach R5

CD ia correct

ztw3587t · Answer

C and D are correct:
The R2 is a L1/L2 router and because of that it sets the attached bit in the Level 1 PDUs and the R1 Router (L1) generates its own default route that points to R2. As a result R1 reaches R5 router and another routers out of L1 area.
