Router vm gets the same ip address even after destroying and recreating it. Since CS does not have a mechanism to notify the router vm after for existing guest vms it won't change the IP address. ASAIK the IP will be released only after deleting that network.

Yesterday i destroyed and restarted router-vm and after that i noticed that from the CloudStack dashboard on Shared Network IP's there is one more extra ip address allocated then its expected. I checked mysql db (select * from user_ip_address where state="Allocated";) to see which ip addresses are allocated and i noticed that there is an ip address like x.x.x.5 is allocated but its not used by any vm or systemvm's. After that i check management server log and i noticed that this ip is high probably router vm's previous ip address. Because on management server log i noticed lines like below: 2016-05-11 16:54:54,374 DEBUG [c.c.a.t.Request] (Work-Job-Executor-116:ctx-19aae9a4 job-1302/job-1303 ctx-eb95bef0) (logid:7f64e204) Seq 10-1563030545674275235: Sending { Cmd , MgmtId: 345050167520, via: 10(kvma16), Ver: v1, Flags: 100011, [{"com.cloud.agent.api.routing.DhcpEntryCommand":{"vmMac":"06:49:d6:00:00:03","vmIpAddress":"x.x.x.4","vmName":"win10CreateTemp444","defaultRouter":"x.x.x.1","defaultDns":"x.x.x.5","duid":"00:00:00:00:00:00:xx:00:00:03","isDefault":true,"executeInSequence":false,"accessDetails":{"zone.network.type":"Advanced","router.guest.ip":"x.x.x.15","router.ip":"169.254.3.100"," router.name":"r-91-VM"},"wait":0}}] } So the suspicious ip address is written in "defaultDns":"x.x.x.5" field and its not correct. I am not currently using dhcp addresses which CloudStack provides but 1 of my ip addresses are gone :) So why this could happen is this be a bug? I also checked logs that defaultDns entry is sometimes correct routervm ip(x.x.x.15) and sometimes old router vm's ip (x.x.x.5).
