The communities 7224:1 – 7224:65535 are reserved by AWS Direct Connect.
AWS Direct Connect applies the following BGP communities to its advertised routes:
7224:8100—Routes that originate from the same AWS Region in which the AWS Direct Connect point of presence is associated.
7224:8200—Routes that originate from the same continent with which the AWS Direct Connect point of presence is associated.
No tag—Global (all public AWS Regions).
7224:8100—Routes that originate from the same AWS Region in which the AWS Direct Connect point of presence is associated
