Segue Level(3)

*Community*

*Action*

3549:600

Customer prefixes marked with community 3549:600 will only be announced

to ISP peers within the same continental region where Global Crossing
learned the prefix (South America).

3549:601

Customer prefixes marked with community 3549:601 will only be announced

to ISP peers within the same RR cluster where Global Crossing learned the
prefix (Brazil peers).

3549:666

Customer prefixes marked with community 3549:666 will not be announced to

any ISP peer globally. This includes all ISP peer BGP-4 sessions but the
prefix will still be announced to Global Crossing BGP-4 customers.

3549:695

Customer prefixes marked with community 3549:695 will not be announced to

any peer AS within the local country, but the route will be announced to
the in country RR for export internationally.

This example below illustrates the use of these communities.

A customer with ASN 65535 sends LEVEL 3 a route tagged with
communities * "3549:8011 3549:8033 3549:8190"
*

When that route is reannounced across LEVEL 3 peering connections:

   - *Qwest (AS 209)* will see an AS path of: "*3549 3549 65535"*
   - *MCI (AS 701)* will see a path of: *"3549 3549 3549 3549 65535"*
   - *OpenTransit (AS 5511)* will not see the route at all
   - All other peers will see: *"3549 65535"*
