AS200753 practices an open peering policy which means that we peer with everyone who wants to peer with us. We do not require any kind of written contract, but assume that you can agree to the following rules:
- Peerings may only send traffic from their own networks and downstreams to us, please do not give others (partial) transit without asking for permission.
- Peerings must operate a Network Control Center (NCC) which can be contacted by email.
- Peerings must be registered at any well known IRR and shall keep all registry data up to date.
- Peerings shall cooperate in any case of network abuse, e.g. filtering DoS attacks.
- Peerings shall enforce a strict routing policy by using filters for their downstreams.
- Peerings shall aggregate their routes as much as possible to avoid inflating the routing tables.
Please also note the following preferences and technical information:
- Prefixes shorter than a /24 (IPv4) or /48 (IPv6) will be filtered.
- Prefixes with private or other invalid ASNs in AS_PATH will be filtered.
- Please use MD5 authentication whenever it is possible for additional security.
- An individual prefix limit will be set for all peerings. The session will automatically recover one minute after you stopped exceeding your prefix limit.
You may use the following two AS sets to include our own ASNs and/or customer ASNs for both IPv4 and IPv6:
We automatically set the following local preference values at our routers, unless overriden by customers with an action community (see BGP communities for further information):
|Route learned from transit||100|
|Route learned from IXP||200|
|Route learned from customer||300|
We are using our secondary ASN AS48550 for all BGP communities to simplify and standardize our routing infrastructure. Please note that we accept some action communities only for our customers. Routes with bogus communities are being rejected by our filters.
