Spirent Test Center: Inject packets with invalid headers

Spirent Test Center: I have some test cases where I need to inject packets with Invalid IPv4 header errors, Invalid IPv6 header errors, packets that will be rejected by ACL filter, Multicast MAC with Unicast Dest IP, Unicast RPF Check Failed, and packets needing ICMP. Is there any documentation that will help with this subject? And do I need to setup these tests in StreamBlocks?

I was able to create Invalid IPv4/IPv6 errors by creating Streamblock and selecting Generate errors under the Payload length. I am getting the results that I need with the incrementing counters. I also setup ICMP Steamblock with incorrect info to be able to see the Unicast MAC Destination Address Mismatch. Now I just need to figure out how to inject packet that will increment the counters for 'ACL Filter Discards', and 'Needs ICMP', and Unicast RPF Check Failed.

Playing around with it. I was able to figure out how to Inject packets to show the ACL Filter counter increment. I added Icmp Redirect header. So now i'm down to two test cases I need. I need to be able to see the 'Needs ICMP' and 'Unicast RPF Check Fail'. Any help on these two would be appreciated.

ok - i'm back. I was able to gather the RPF check by changing the source ip to incorrect ip and generate stream. Now working on trying to get the 'Needs ICMP'. Still looking for help on this one part. I will continue to play around with the settings.
