At present the 6Bone defaults to statically configured tunnels but the
use of RIPv6 is beginning between those tunnels that support it. We are
promoting the idea of using IDRP for IPv6 for exchanging routing
information which has the advantage of offering more effective
scaleability. The protocol is now running successfully on the 6Bone 
between UNI-C/JOIN/IFB/and TELEBIT (with NIST and others starting soon).

The routing table snap-shot shown below, taken from UNI-C's operational
IPv6 network shows some of the possible combinations for managing
multiple tunnels.

Hope this helps,
