Sorry for making such a reference :) . In that configuration, we have
2 routers R1 and R2. R1->10.0.0.1 and R2->10.0.0.2. Both are default
routers. When R1 fails, R2 has to take over the traffic to R1 and when
R2 fails, R1 has to take the traffic to R2. (network is unreachable
only when both routers are down).
If this is not still clear, let me know.

Yes. It is not accepting the packet because of the mismatch in MAC
address.( I am not changing the original NIC address of the director
because I need 2 directors simultaniously. Each instances should
accept packet to a particular MAC)
Thank you for spending your time for me
