Current RIS Routing Beacons

Note: IPv6 beacons and anchors are now being announced from the RRCs. See below for details.

All RRCs:

• Announcements at 00:00, 04:00, 08:00, 12:00, 16:00, 20:00 (UTC)
• Withdrawals at 02:00, 06:00, 10:00, 14:00, 18:00, 22:00 (UTC)

Comments:
The RIS Routing Beacons were initiated to assist studies concerning unwanted effects on convergence when applying Route Flap Damping practices.

All IPv4 beacon prefixes are announced with additional attributes. We now overload the BGP AGGREGATOR attribute to tag each announcement with a timestamp, a sequence number and the identifier of the RRC making the announcement. These are encoded as follows:

AGGREGATOR IP ADDRESS: 10.x.y.z, where x, y and z form a 24-bit count of the number of seconds between the start of the month and the time of the announcement. AGGREGATOR AS NUMBER: 64512 + n, where n is a 10-bit number encoded as

    MSB                                   LSB
    +---+---+---+---+---+---+---+---+---+---+
    | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 |
    +---+---+---+---+---+---+---+---+---+---+
    |    RRC ID     |    Sequence Number    |
    +---+---+---+---+---+---+---+---+---+---+
  

Adding 64512 brings the resulting number into the private AS number range.

Additionally, we announce an anchor prefix from each RRC. These are permanently announced and can be used to differentiate between activity seen as a result of changes on the originating RRC and that seen for other reasons (it the anchor flaps, it could mean that the RRC was reloaded and activity of the corresponding beacon can be ignored when doing analysis of the RIS data).

RRC14 / RRC03:

• Permanent announcement from RRC14
• Announcements from RRC03 at 00:00, 04:00, 08:00, 12:00, 16:00, 20:00 (UTC)
• Withdrawals from RRC03 at 02:00, 06:00, 10:00, 14:00, 18:00, 22:00 (UTC)
• 84.205.72.1 is also configured as a "pingable address"

Comments:
Beacon initiated to simulate anycast failover from RRC14 to RRC03.
84.205.72.1 is also configured as a "pingable address".
