All,
Thank you very much for your feedback and help.
In my particular case I reverted route map logic
(old, good deMorgan Laws) to something like this:
route-map eBGP-OUT deny 10
match community NEITHER_US_NOR_CUSTOMERS
route map eBGP-OUT permit 20
match community PREPEND_1
set as_prepend 18747
route map eBGP-OUT permit 22
match community PREPEND_2
set as_prepend 18747 18747
(...)
route map eBGP-OUT permit 99
ip comunity-list standart NEITHER_US_NOR_CUSTOMERS deny 18747:610
ip comunity-list standart NEITHER_US_NOR_CUSTOMERS deny 18747:620
ip comunity-list standart NEITHER_US_NOR_CUSTOMERS permit
Thanks again,
Przemek
PS. this is actually mentioned on page 356 in Parkhust,
but I somehow overlooked it.
