Peering requests: Please see

for more informations
========================================================================
remarks: ========================================================================
remarks: - RFC1918 and other reserved networks and subnets are not permitted.
remarks: - Advertisements with ASes in the path, defined in RFC 4893, 5398, 6996,
7300, 7607 are marked and set with localpref = 1000000 and next-hop =
blackhole.
remarks: - Prefixes shorter than /8 or longer than /24 are not permitted.
remarks: - Advertisements containing the AS of a network with which we have a
non-customer peering relationship is not permitted (ie customers are
not allowed to advertise transit to our UpStream).
remarks: - Advertisements tagged with our own "internal use only" communities
(ie communities outlined em http://start.psi.br/peering) will have
all of their communities stripped from them at entry, and any
communities meant to affect localpref, prepending, etc. are thus
ignored.
remarks: - All customer peering sessions are prefix-filtered and AS-PATH, inbound
using a customer specified import policy pulled from any known public
registry.
remarks: - Prefixes not matching the per-peer import policy as documented above
are not permitted.
remarks: - Localpref will be set to 200 by default, subject to modification
based on received communities as outlined below.
remarks: - A hard limit is placed on the number of routes a peer is allowed to
announce to us. This number is based on their registered routes plus
a bit of extra overhead.
remarks: - MEDs are overwritten unless special arrangements have been made.
