Well... R1 appears to have two links in the same subnet. So the question becomes how are things being routed? If you aren't running any routing protocols yet, one of the best commands you can do to watch what is happening is "debug ip packet". Try that out on all three of your routers, and see whether the packets from R2/R3 are coming IN to R1, and then try to look at where they are going back out to or if there's any failure.

But I am not able to ping R1 -- R2 and R1-- R3 . What is wrong in above config ? 2) If I am using point to point sub-int @ R1 ; do I need to have point to point sub int on R2 and R3 as well . Cant this be done on main interface on R2 and R3 Gaurav Madan. Gaurav Madan.
