Issue: When there is no traffic for a group, the LHR and RP take the default KAT+Join timer expiry of a maximum of 480 seconds to clear the S,G . However, in the FHR, we update the state from JOINED to NOT Joined, downstream state from PPto NOINFO. This restarts the ET timer, causing S,G on FHR to take more than 10 minutes to age out. In other words, Consider a case where (S,G) is in Join state. When the traffic stops and the KAT (210) expires, the Join expiry timer restarts. At this time, if we receive a prune, the expectation is to set PPT to 0 (RFC 4601 sec 4.5.2). When the PPT expires, we move to the noinfo state and restart the expiry timer one more time. We remove the (S,G) entry only after ~10 minutes when there is no active traffic. Summary: KAT Join ET 210 + PP ET 210 + NOINFO ET 210. Solution: Delete the ifchannel when in noinfo state, and KAT is not running. Ticket: #13703 Signed-off-by: Rajesh Varatharaj <rvaratharaj@nvidia.com> |
