[c-nsp] 6to4 relay setup?

[David Prall]

In a 6to4 auto tunnel, you use 2002:192 88:99 1::1/16 as your address. Where
the IPv4 address is converted to Hex. I'm not sure you should anycast the
address, since this address is typically used as your BGP next hop. Might
load balance it with sticky, only need an IPv4 slb setup. If anyone has done
anycast for this, let them discuss. The possible route churn scares me.
