Fwd: Opaque pipe in bird 2.0?

[Piotr Wydrych]

Bumping up - even if there is no good answer to my question, I think 
that the documentation should be fixed :-)

Hi,

Having a table with 2 paths per prefix, I need to send only the best 
path to another table, like this:

+------+       +------+
|table1|       |table2|
+------+       +------+
         \     /
          \   /
          +v-v+
          |all|
          +-+-+
            |
            |
       +----v----+
       |best_only|
       +---------+

As far as I remember, I could use pipe with opaque mode to achieve that 
in Bird 1.6. After mode has been removed in Bird 2.0, is there any 
simple way to do it by using pipe and filters?

Currently, I configured to have a BGP session to itself to send the best 
paths, but I consider it as a dirty workaround...

BTW, documentation for pipe in 2.0 still mentions the opaque mode - 
http://bird.network.cz/?get_doc&v=20&f=bird-6.html#ss6.8 (2nd and 3rd 
paragraph).

Best,
Piotr
