Bug Resolved Cannot Reproduce Dana Kutenicsova Giles Heron Mon, 22 Jun 2015 14:30:35 +0000 Sun, 3 Mar 2019 11:50:27 +0000 Thu, 25 Jun 2015 09:32:58 +0000 Bugzilla Migration Bugzilla Migration BGP 0 2 <p>Attachment karaf.zip has been added with description: zipped logs</p> <p>OK - so it gets worse <img class="emoticon" src="https://jira.opendaylight.org/images/icons/emoticons/sad.png" height="16" width="16" align="absmiddle" alt="" border="0"/></p> <p>turns out I can "fix" this reliably if the one prefix advertised by the second peer is also advertised by the first peer.</p> <p>BUT</p> <p>when I do that I see that the LocRib entry for that prefix goes via the first peer even though the AS-path is shorter via the second.</p> <p>Attachment karaf.zip has been added with description: zipped logs from run with RIB fetch bug</p> <p>So testing again with Lithium RC2</p> <p>Java version is:</p> <p>java version "1.7.0_60"<br/> Java(TM) SE Runtime Environment (build 1.7.0_60-b19)<br/> Java HotSpot(TM) 64-Bit Server VM (build 24.60-b09, mixed mode)</p> <p>So suspicion here is 2 bugs.</p> <p>The first one is possibly in RESTCONF - where we can't fetch the RIBs once a second peer comes up, in the case where the routes don't overlap between the peers.</p> <p>the second is in BGP - where we pick the "longer" AS path instead of the shorter one.</p> <p>I found the second one because i changed my XR router config to do a next-hop-self for any routes learned from the second peer so that the first peer also advertised the route advertised by the second peer (in this instance 192.168.118.0/23).</p> <p>So the logs I just sent were for the first issue.</p> <p>The topology is:</p> <p> (AS 64496)<br/> OpenDaylight SDN Controller</p> <div class='table-wrap'> <table class='confluenceTable'><tbody> <tr> <td class='confluenceTd'> \<br/> (AS 65506) </td> <td class='confluenceTd'> (AS 65504) \ (AS 65505)<br/>

172.23.29.116 would also advertise 192.168.118.0/23.</p> <p>2) "fixed" the config of 172.23.29.125 so its peer-id was 172.23.29.125 instead of 192.168.100.5 (that's why we were getting no data for peer-id 172.23.29.125!)</p> <p>no HTTP 500 error now, but we see the longer path to 192.168.118.0/23 via 172.23.29.116 being preferred to the path via 172.23.29.125.</p> <p>logs to follow.</p> <p>will then revert the next-hop-self to verify that the peer ID has no effect on the HTTP 500 error.</p> <p>Attachment karaf.zip has been added with description: zipped logs from run with "longer path" bug</p> <p>ok - so tested with the peer-id 'fixed' but with no next-hop-self (so there would be no overlap between the routes from 172.23.29.116 and from 172.23.29.125).</p> <p>initially it seemed to 'work' - I did a GET on the RIBs and could see both peers</p> <p>but immediately after I got the HTTP 500 (still there).</p> <p>i now find I can do a GET on peer 172.23.29.125 successfully but that a get on peer 172.23.29.116 gives me HTTP 500.</p> <p>I then find I can do GETs on 172.23.29.125/adj-rib-in and 172.23.29.125/effective-rib-in.</p> <p>but a GET on 172.23.29.116/adj-rib-out gives me HTTP 500.</p> <p>likewise if I go one step further and do a GET on 172.23.289.116/adj-rib-out/tables/bgp-types:ipv4-address-family/bgp-types:unicast-subsequent-address-family I get the HTTP 500.</p>
