Comment 3 Weibin Liang 2021-09-30 14:12:19 UTC 
Testing failed on 4.9.0-0.nightly-2021-09-30-022250 today, PR may not merged yet.
Comment 4 Tim Rozet 2021-10-01 14:44:44 UTC 
Hey Weibin, this BZ is targeting 4.10, so you need to get a 4.10 nightly:
https://amd64.ocp.releases.ci.openshift.org/#4.10.0-0.nightly
Comment 5 Weibin Liang 2021-10-01 20:47:45 UTC 
Tested and verified in 4.10.0-0.nightly-2021-10-01-141332. Muticast traffic cross three nodes.
