Unrecognized attribute flagged Well Known

Hello ODL-BGPCEP

For the routes inserted into odl bgp-app-rib with an unrecognized attribute as follows,

"prefix": "192.1.50.0/32",
"attributes": {
"unrecognized-attributes": [

{ "type": 30, "transitive": true, "value": "11110000", "partial": true }

]
(attachment - route.json)

the unrecognized attribute of this route is being further advertised by odl-bgpspeaker as 'well known' instead of 'optional' as seen in the wireshark trace of the bgp update message-

Unknown (9 bytes)
Flags: 0x60 (Well-known, Transitive, Partial)
0... .... = Optional: Well-known
.1.. .... = Transitive: Transitive
..1. .... = Partial: Partial
...0 .... = Length: Regular length
Type code: Unknown (30)
Length: 6 bytes
Unknown (6 bytes)

Due to this wrongly set flags, the attribute is not being parsed by other peers specifically quagga bgp router.

It will be really helpful if you can please see it to it.
The version of odl-bgpcep used is 0.5.3-SNAPSHOT.

Thanks and Regards
