[c-nsp] BGP, auto-summary and IPv6

[Aaron Daubman]

Greetings,

What affect, if any, does the '(no) auto-summary' command have on
unicast IPv6 BGP address-family configuration.

In most of the information I've found, it is stated (or implied) that
the auto-summary command applies only to ipv4.

However, the following document notes "12.2(33)SRB - Support for IPv6
was added." for the command:
http://www.cisco.com/en/US/products/sw/iosswrel/ps5187/products_command_reference_chapter09186a00801d6610.html#wp1961380

I was wondering if somebody could explain if this was just a typo or
if there is a 'magic' "auto-aggregation" feature in BGP for IPv6
routes (and if so, what the "classful network boundaries" would then
refer to)?

Thanks, as always.
