[peering]
== peering

i am accepting peerings in the UK & Ireland.
please see the link:nodes/[list of nodes] for information about nodes
accepting new peerings.
all nodes support multiprotocol BGP with extended next hop for IPv4 prefixes;
BGP itself is only supported over link-local IPv6 addresses.

peering requests with an excessively high rtt may be rejected to preserve
network quality.

to request a peering, please mail ft.dn42@le-fay.org and include:

* the node you want to peer with
* your DN42 ASN
* your Wireguard endpoint address, port, and public key
* your BGP link-local address
* whether you want IPv4 routes, IPv6 routes, or both
	(note that in any case, BGP peerings are always over IPv6 link local
	addresses)

[.red]#*# - these communities should never be seen on DN42

the node-specific and region-specific communities are only attached when the
route is originated or received from an external peer.  for example, a route
tagged with 4242421495:2:1 was either received by rose from an external EBGP
peer, or was locally originated on that node.  therefore, any route should only
have a single node-specific and region-specific community.
