Duplicate of ip addresses

[AndreyVakin]

Hi everybody
In the documentation, I read about the possibility of checking for duplicate ip addresses using openBMP.
Someone can explain my how it wok, which criterias of duplicate?

For example: we wanna check duplicate of ip addresses on super spine level. In our tology two a leaf switches advertising of the same network to spine, spine to super spine.
From the super spint point of view it has two same route from spine but with different origin AS due to a leaf switches has AS100 and AS200. We need to make sure that the same route does not appear from AS300
Will this be considered a duplicate for openbmp?
