Explicit as-path filtering (with prepending allowed)

Hi guys,

Is there perhaps an equivalent in BIRD for the following...

^(65000_)+(65101_)+(65253_)+$

The closest I could come was the following, but I am unsure if it would
match if any of the networks prepend.

if (bgp_path ~ [= 65000 65101 65253 =])


-N
