Please respond on our mail and add my mail id (apoorva.maheshwari@ericsson.com). quick response will be appreciated. We have upgraded from BIND version 9.11.0 to 9.11.1-P3 and observed that Recursion available (RA) bit is set to 0 in case of update response. This bit was set to "1" when using earlier version of BIND (9.11.0) by default. Steps to reproduce : 1. Updated BIND version from 9.11.0 to 9.11.1-P3. 2. Executed nsupdate command: nsupdate > server 127.0.0.1 > zone 9.msisdn.sub.cs > update add 9876544.9.msisdn.sub.cs 300 CNAME SDP1.cs > send 3. Verify the TCP dump for the response received from BIND. The RA bit is set to '0'. This bit was set as '1' in BIND 9.11.0 Note : 1. We tried adding "allow-recursion" in option block in named.conf, but RA bit was still set to 0 options { ... allow-recursion { any; }; 2. The behavior is same for Bind version 9.11.2 as well. Recursion available (RA) bit is set to 0 in case of updates. Attaching here with the tcp dump as well as the snapshots. Is this something which have been introduced now ? Or is it a bug ? --- This email was received through isc.org Bug Submission Form
