Thanks. The think to know is that a channel can be specified in this
places as PROTOCOL.CHANNEL , so
  show route import table ASpeer1.ipv6
does work.
This is not mentioned in the User's guide, I think.
If you want I can do a patch, also mentioning the "import table" syntax
in doc and help output.

BIRD BGP by default operates without import tables, in which case received routes are just processed by import filters, accepted ones are stored in the master table, and the rest is forgotten. Enabling import table allows to store unprocessed routes, which can be examined later by show route, and can be used to reconfigure import filters without full route refresh. Default: off.
