Hi,
This is in reference with IEWB VER3.0 LAB5 Task4.6
R4
|
R5 -------FR------ R2
|
R3------>
There is PPP over serial between R4 and R5. With the above setup i am
having full connectivity. As per the requirement of the LAB, it states
that the PPP link between R4 and R5 should come up when R5 loses its
connectivity with the FR link. And this is to be done using a Floating
static route. As expected the link does come up. The problem is that,
i am able to ping the Loopback and FR interfaces of R4 but cannot ping
the R2 or R3 or any other network beyond R4. From R2 and R3 , i am
able to ping Loopback interface of R5 without any problems.I have
posted all the config below.

R3 has got a path through R4 to R5 and back.But R5 is not able to go
further from R4. I have redistributed the statis routes on R4 as well.
Cant find what would be the reason.
Your help is much appreciated!
