Abstract:
With network-based applications becoming prevalent, solutions that
provide connectivity over wide area become more attractive for
customers. In small-to-medium enterprise sector, Virtual Private LAN
Service (VPLS), is a very useful service provider offering. It
creates an emulated LAN segments fully capable of learning and
forwarding Ethernet MAC addresses.
Today, in VPLS implementations, within the context of a VPLS PE (VE),
a single-site is selected from which all PWs are rooted. The site-
election mechanism is usually hard-coded by different vendors (e.g.
minimum or maximum site-id), and as such, is outside end-users
control. This offers no flexibility to end-users as it forces them to
define the site-id allocation scheme well in advance, or deal with
the consequences of a suboptimal site-id election. Moreover, whenever
the elected site-id is declared down, the traffic to and from all
other sites hosted within the same VE is impacted as well.
This draft defines protocol extensions to keep core-facing
pseudowires (PWs) established at all times, regardless of the events
taking place on the attachment-circuit (AC) segment when using the
BGP-based signaling procedures.
