BGP Communities

Network Utilization

These communities are recognized and used by AS6667

NOTE: These communities will evolve with changes in transit providers and exchange points. If you are having problems with the communities, check here first to see if a community has been changed or removed. We will try to not change the meaning of a community unless the new meaning is a direct replacement.

Set LOCAL_PREF to 110

The communities that set the local preference within our network are usable by all customers and peers. The default local preference for customers is 101 and for peers it is 100. The default local preference for transits is 90. Local preference of 80 is meant for backup provided by a customer or peer to someone else and the local preference of 110 is meant for overriding routing to choose a certain path over others. Peers can't set a preference of 110.

The communities that control route announcement to peers and transits are only available to customers. The x specifies what the action for the said target is:

0 Announce as is ..
1 Announce with 6667 prepended to as-path ...
2 Announce with 6667 6667 prepended to as-path ...
3 Announce with 6667 6667 6667 prepended to as-path ...
9 Don't announce ... (default and takes precedence if present)

We will also let external communities through from customers. This will enable customers to use similar communities of our peers and transits. Some pages describing these communities have been collected at the end of the page.

These communities are tagged on all routes to distinguish their origins. They are sent to everyone but not excepted from outside. They are there to let customers filter routes based on route source.

A normal customer announces all their routes to us with communities 6667:900, 6667:1000 and 6667:2000. When Eunet receives the routes, they are tagged with 6667:300x and the local location community (6667:4xxx.)
