Hi Chandrasekar,

If you are able to ping the destination from one source interface and you aren't able to ping from a different source interface on the same router, the problem is the following:

The route to source interface that you are not able to ping from is not known to the destination device.


- Check if there is a route back from the destination device to the source interface.

- Check if the subnet of the source interface is advertised in a routing protocol at all.

- Check if the advertisement is not filtered anywhere along the way and the destination device receives this update.
