I am using IxN2X Packets and Protocols from Ixia. I need to send RouterSolicitation packets with unspecified address at source address field of Ipv6 header. I have tried to construct a packet in traffic stream, but it is not formed as intended. The packet capture shows the contructed packet to be Neoghbor Solicitation(with improper source and destination address in ipv6 header), and worse thing is it is not recognized as a Neighbor Solicitation packet in the SUT side.

There is way to send RouterSolicitation through the emulation itself. But it is taking a valid link-local address - I want the '::' address be there instead.

Emulation: PPPv6 emulation with NDP enabled.

Thanks in advance
