Hi All, We are executing IPv6 Ready Core Protocols Test Specification for Linux kernel 5.10.201 for USGv6 certification. Under Test v6LC.2.2.23: Processing Router Advertisement with Route Information Option (Host Only) , there are multiple tests from A to J category. We are facing issues with test category F which is described below. Part F: PRF change in Route Information Option. Here is what is happening: Router Advertisement sent from router A with PRF low. Router Advertisement sent from router B with PRF medium. Echo Request. Echo Reply expected to be directed to router B. However, reply is sent to router A Router Advertisement sent from router A with PRF high. Echo Request. Echo Reply expected to be directed to router A. However, reply is sent to router B We tried introducing delay in the test case between each request to allow processing to complete. This did not help. Has anyone observed this behavior? Is there a patch for this issue ? Please suggest how to go about finding a solution for this failure. If I need to post this to other linux network users forums as well, please let me know. Regards, Jayalakshmi
