Peer with us!¶

If you have a VM / IPv6 network from us and want to peer with us, the following steps should help you:

• Send a request to support at ungleich.ch containing your
  • ASN
  • Networks

ungleich routers¶

To BGP peer with us, you will need to establish 2 BGP sessions (for redundancy reasons). The routers depend on the IPv6 that your endpoint has:

Your VM is in ...	... then peer with
2a0a:e5c0:0:2::/64	2a0a:e5c0:0:2::3 2a0a:e5c0:0:2::4
2a0a:e5c0:0:5::/64	2a0a:e5c0:0:5::3 2a0a:e5c0:0:5::4
2a0a:e5c0:2:2::/64	2a0a:e5c0:2:2::5 2a0a:e5c0:2:2::6

You will receive the full IPv6 routing table from us.

Configuration for you (the peer)¶

If you are using bird for peering, your configuration can look similar to this:

# Adjust filters to your own preference
filter from_ungleich {
  accept;
}
filter to_ungleich {
  accept;
}

protocol bgp ungleichrouter1 {
    local as YOURASN;
    neighbor SELECT_FROM_TABLE_ABOVE1 as 209898;

    import filter from_ungleich;
    export filter to_ungleich;
}

protocol bgp ungleichrouter2 {
    local as YOURASN;
    neighbor SELECT_FROM_TABLE_ABOVE2 as 209898;

    import filter from_ungleich;
    export filter to_ungleich;
}

Configuration for ungleich¶

These instructions are for ungleich staff.

• Create / edit in the cdist type __ungleich_bgp_router:
  • ${peer}_v6.conf (very similar to the peer example above)
  • bird6.conf: define networks of peer (net_${peer})
  • general.conf: add appropriate filters
• Apply bgp configuration or full cdist config
  • cdist config -vvp6 -bj5 router{..}.place{..}.ungleich.ch # full
  • echo __ungleich_bgp_router | cdist config -i - -vvp6 -bj5 router{..}.place{..}.ungleich.ch # routing only
• Verify that config has been applied
  • bird6c
  • conf
  • show route protocol $peer
• Send an update by mail to init7 & netstream for the new prefixes
  • best is via RT
    [[datacenterlight:Email_template_to_DCL_customers#Network: Inform changed BGP to INIT7/NETSTREAM]]

RIPE¶

Our networks are registered with ripe.

Maintainer¶

All objects should have the mnt-by flag of mnt-ungleich. This maintainer handle is usable by all our LIR accounts.

CLI¶

A cli for accessing RIPE's rest interface is developed on https://code.ungleich.ch/ungleich-public/ungleich-cli
