A. Durand: AUTHOR [+2]
The 6Bone is an environment supporting experimentation with the IPv6 protocols and products implementing it. As the network grows, the need for common operation rules emerged. In particular, operation of the 6Bone backbone is a challenge due to the frequent insertion of bogus routes by leaf or even backbone sites.

identifies guidelines on how 6Bone sites might operate, so
that the 6Bone can remain a quality experimentation environment and
to avoid pathological situations that have been encountered in the
past. It defines the 'best current practice' acceptable in the 6Bone
for the configuration of both Interior Gateway Protocols (such as
RIPng [RFC 2080]) and Exterior Gateway Protocols (like BGP4+ [RFC

2. Basic principles
The 6Bone is
structured as a hierarchical network with pseudo Top
Level Aggregator (pTLA) sites, pseudo Next Level Aggregator (pNLA)
sites and leaf sites. This topology supports the IPv6 address
aggregation architecture as described in . The 6Bone backbone is
made of a mesh interconnecting pTLAs only. pNLAs connect to one or
more pTLAs and provide transit service for leaf sites.

pTLA sites MUST use BGP4+ [RFC 2283] as the mandatory routing
protocol for exchanging routing information among them.
sites or pNLAs SHOULD also use BGP4+. Regular sites MAY
use a simple default route to their ISP.
