Peering policy for AS1741
The peering policy of AS1741 is to peer with other networks
whenever it is of interest for Funet customer
organizations and CSC. The purpose of peering is to improve connectivity
as well as to optimize the use of common infrastructures.
Peering is based on an agreement between CSC and the other network.
To make these rules more concrete, the following guidelines will be
- AS1741 establishes new peerings only in public peering points (IX) in Finland
- AS1741 decides case-by-case in which Finnish peering points it is present
(in 2004 this means Ficix1 and Ficix2)
- AS1741 decides case-by-case whether to peer with a network in an IX,
and the decision is re-evaluated as needed.
The following principles are followed in peering:
- For peers, AS1741 announces AS-FUNET, which includes Funet customers.
We do not accept these prefixes or parts of them to be announced to
us by any peering partners.
- In peerings, database-based (RIPE DB) automatic AS-path filter generation
system is used. Thus the peering partners are assumed to keep their database
- Prefixes announced to us are sanity-checked,
and violation prefixes will be removed.
In case of severe malfunctions, individual peerings may be shut down
- Standard security mechanisms like MD5 are implemented.
