Traffic between VRFs through the RIB group route leak is not working as expected as packets are not getting properly decoded internally.
To identify this issue a source ping for the destination of other VRFs could be done. The ping will fail.

On the ACX7024 platform, traffic between Virtual Routing and Forwarding (VRFs) through the RIB (Routing Information Base) group route leak is not working as expected and may cause traffic disruption.

This issue might be seen if the following conditions are met:
*On ACX7024 platform
*Multiple VRFs are configured
*The RIB group is used to leak routes between the VRFs

This is fixed via belpw PR.
