Consider the following topology

N1 -> Subnet1 - > VM1(DPN1)

N2 -> Subnet2 -> VM2(DPN2)

VPN1(RD:10:1 iRT=20:1 eRT=10:1)

VPN2(RD:20:1 iRT=10:1 eRT=20:1)

N1 associated with VPN1

N2 associated with VPN2

FIB flow.

Observed Remote FIB flows have missing action of setting destination mac address for the corresponding destination IP.

Other cases of it is set.
