Why spirent do not send neighbor advertisement?

This is the interface configured on the Linux machine.

vlan1.202: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 9216

inet 22.22.2.1 netmask 255.255.255.0 broadcast 22.22.2.255

Multiple NS packets have been received on the spirent(virtual ip 22:2::10)

But Spirent is not sending NA packets for any of the NS packets received. Why its not sending?
