floating-ip update does not take effect

[Deepak Agrawal]

We are trying to disassociating a floating-ip from a VM. We call contrail-API to update "floating-ip" with VNI as Null. Though, contrail API server returns 200, this does not take effect on MX where we checked the route. Route is still pointing to compute VM. Following is snip of API which fails to update floating-ip

contrail-api-0-stdout.log:INFO:vpc-ctrl1:contrail-api:Config:0:__default__ [SYS_INFO]: VncApiConfigLog: api_log
 = << identifier_uuid = 901bec08-6452-4343-8aa3-0e41202cab9d <snIP>

-8aa3-0e41202cab9d', 'virtual_machine_interface_refs': []}} domain = default-domain >>
contrail-api-0-stdout.log:127.0.0.1 - - [2016-11-29 13:33:06] "PUT /floating-ip/901bec08-6452-4343-8aa3-0e41202
cab9d HTTP/1.1" 200 256 0.009325

Returned 200 but /32 route on MX for this floating-ip is still intact in BGP. Don't see any error in if-map server etc..

Any pointers how to debug this problem ? we are using contrail 2.2.0
