Last Updated: 2021-01-28

ENABLING CUSTOMERS TO CONTROL THEIR IPV4 AND IPV6 TRAFFIC IN-LINE WITH THEIR BUSINESS NEEDS

Telia Carrier's Internet Services on AS1299, offers a range of BGP Community options to help control the scope and route preference of traffic.

NOTE & DISCLAIMER

- Unless stated otherwise, these features are available for all BGP customers.

- All of these are subject to change; Customers and Peers should check the Portal and the RIPE database entry for AS1299.

These are provided on a Best Endeavour basis and not subject to product-specific SLAs.

Visit the RIPE database to see the entry for AS1299

PREPEND AND DO NOT ANNOUNCE

IP Transit customers can use predefined communities to prepend or deny announcements to specific Telia Carrier peers. Communities are checked at AS1299 exit points, starting with the most specific (i.e. per- peer communities checked before regional communities).

Allowable values for the regional & peer prepend are 0, 1, 2 & 3, denoting the number of prepends to be applied. Telia Carrier’s community support also allows customers to set multiple community actions. For example, simultaneously setting a regional prepend of 1x and a peer- specific prepend of 2x. A prepend of zero is also possible.

PLEASE NOTE: Prepend and Do Not Announce community actions are not available for Content Connect customers.

REMOTE BLACKHOLE COMMUNITY

The remote blackhole community allows IP Transit customers to tag announced prefixes with a community (see below) that will trigger Telia Carrier to automatically discard (null-route) traffic destined for the tagged prefix as soon as it enters our network. IPv4 and IPv6 prefixes can be tagged up to a /32 or /128, respectively.

While not enabled by default, this capability can be requested when ordering a new service or via a change order for existing services.

For security purposes, customers must use per-prefix BGP filters and register and maintain their prefixes and route objects in the applicable Internet Routing Registry database.

LOCAL PREFERENCE ACTIONS

Customers also have the option to change the default local preference setting within AS1299 from 200 (customers) to either 150 (Peerings) or 50 (Backup).

Community Description Local Preference
1299:50 Lowest Possible, Backup  50
1299:150 Equal to Peer, Backup 150
Default Equal to Customer 200

 

BGP GRACEFUL SHUTDOWN

AS1299 Accepts and Honours the BGP Graceful Shutdown community; 65535:0 - compliant with IETF RFC8326. The purpose of this is to reduce the amount of traffic lost when BGP sessions are to be shut down, for example, during planned work. When announced by a customer, AS1299 will set local-preference to 20, which will ensure the use of alternative paths, if they exist. During Planned Works, AS1299 will always signal this community to customers and peers, allowing them to also re-route within their network.
