remarks: =========================================================
Any Carrier originated route will be tagged with 16724:65000.
Any Customer originated route will be tagged with 16724:65001.
Any Peer originated routes will be tagged 16724:65002.
=========================================================
Advertisements with reserved ASes (ie 64512 - 65535) in the path are not accepted or advertised.
Prefixes shorter than /8 are not accepted or advertised.
Prefixes longer than /24 are not accepted or advertised.
RFC1918 and other reserved networks are not accepted or advertised.
All BGP Session are Prefix-Filtered based on routing registry entries.
All routes will be tagged with an Origin Community.
That amounts to 16724:z Hence a route from
AS3356 will be tagged with 16724:3356.
=========================================================
Prepending:
Prepending is available to customers on a per carrier basis by community. The communities for prepending are formed per this design:
16724:xy where x is the number of prepends from 1 to 4 and y is the code of the carrier (Listed Below).
To prepend three times to Level3 include this community in your announcement:
16724:31
To prepend twice to BrightHouse include this community:
16724:23
========================================================
No-Advertise:
Standard No-Advertise communities will be accepted and dealt with properly, But additional more specific no-advertise communities are available:
16724:6z where z is the Code of the carrier (Listed Below).
This will ammount to a No-Advertise community to the carrier specified.
Example:
To prevent advertisment of a route to Level3 attach this community
16724:61
========================================================
Carrier Codes:
Level3 is carrier 1
XO is carrier 2
BrightHouse networks is carrier 3
Cogent is carrier 5
WOW! is carrier 6
