[6lowpan] ND-18 Multiple Prefix

[Tom <[e-mail]>]

Hello Everyone,

Kindly clarify does ND-18 support multiple prefix (and multiple
address/node derived from these prefixes).
I raise this doubt because the assumption section,  bullet 4 says -> a
6lowpan is configured with one or more prefixes,
and the final bullet says -> since the 6lowpan shares one single prefix
through out the network.

Further, if 6LBR is advertising multiple prefix and host configures
multiple global addresses based on these prefix how will they be useful.
Will not the 6LR/6LBR reject registration through ARO from different source
address but same EUI-64 (same node auto configuring with different
prefixes).

Regards,
Thomas Chacko
