This service should be considered to be in BETA testing.
And as such it is being offered with no implied warranty
and free of charge for now.
TREX is running two route servers to facilitate the interconnection
of members. The route servers accept all RIPE registered routes
from all members that wish to peer with the route servers and
announce those routes to all members that wish to receive them.
They are eBGP route reflectors in essence.
Both route servers are running BIRD
right now. However, we have plans to change one of them to run some other
software to protect the service from bugs occuring in either one of
the chosen software routing daemons.
Further details are as yet unavailable.
The AS number that the servers use is 197032
which is a 32-bit ASN. Members that wish to peer with it, but who
cannot configure 32-bit ASNs in their routers should configure
23456 instead.
The addresses of the servers are 195.140.192.1, 195.140.192.2,
2001:7f8:1d:4::1 and 2001:7f8:1d:4::2.
Members who have transit-customer relationships with other members
on the exchange should be careful about using the route servers in
case they might inadvertently damage the functionality of said
transit. The communities listed below can be used to limit route
visibility in such cases.
BGP Communities Supported
| Community |
Announce? |
| 0:ASN |
not to ASN |
| 0:65534 |
not to anyone |
| 65534:ASN |
yes to ASN |
The route servers respect some parametrized BGP communities.
To forbid the announcement of a route to a certain peer, use
the community 0:peer-AS. For example to forbid announcing the
route to AS1234 and AS2345 tag the route with the following
communities:
0:1234 0:2345
To change from opt-out style announcement of routes
to opt-in style announcement, use the community 0:65534.
Routes with that community will not be
announced to any peer unless the community 65534:peer-as appears on
the route. For example, to announce a route to only autonomous systems
29243 and 51164 use the following set of communities:
0:65534 65534:29243 65534:51164
These communities are untested with 32bit autonomous system numbers.
We shall worry about that once we get a member that has one.
