I got an email response on 11th Sep when made a complaint for the same, they
said, it is one of our customer's prefix. THATS IT.

They didn't share any reason for rogue attributes, for them it is more
likely a Juniper box their client is using.

Very helpfull info though :)

Regards,

Aftab A. Siddiqui
