Communities Used by ElisaIP

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.

Local Preference

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.

Announce Route

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.

Route Origins

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.

Standard customers announce all their routes to
us with communities 6667:900, 6667:1000 and 6667:2000. When Elisa receives
the routes, they are tagged with 6667:300x and the local location
community (6667:4xxx.)
