Blanket rules applied to every INOC client peering session
RFC1918 and other reserved networks and subnets are not permitted.
Advertisements with reserved AS's in the path. (ie: 64512 - 65535) are not permitted.
Prefixes shorter than /8 or longer than /24 are not permitted.
Advertisements containing the AS of a network with which we have a non-client peering relationship are not permitted
(ie: clients are not allowed to advertise transit for Sprint, AT&T, etc).
Advertisements tagged with communities not listed below will have all of their communities stripped from them at ingress, and any communities meant to affect localpref, prepending, etc are thus ignored.
All client peering sessions are prefix-filtered inbound using a client specified import policy pulled from any known public registry.
Localpref will be set to 200 by default, subject to modification based on received communities as outlined below.
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.
