[jira] [Commented] (CLOUDSTACK-5908) Fail to add VXLAN network to
instance
[ https://issues.apache.org/jira/browse/CLOUDSTACK-5908?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13877199#comment-13877199 ]
Toshiaki Hatano commented on CLOUDSTACK-5908:
---------------------------------------------
Hi Nux,
This basically happens when modifyvxlan.sh cannot find source IP address for multicast traffic.
Could you paste 1) traffic label setting 2) "ifconfig -a; brctl show" result on the host?
