for both:
!
   neighbor 91.195.159.6 external
     remote-as 30799
     description peering Internetia-Dworek
    address-family ipv4 unicast
       maximum prefix 100
       route-map direct-peering-rix-in in
       route-map direct-peering-rix-out out
!
   neighbor 91.195.159.10 external
     remote-as 196858
     description peering BetaSoft
    address-family ipv4 unicast
       maximum prefix 100
       route-map direct-peering-rix-in in
       route-map direct-peering-rix-out out
!

so, exaclty the same.

Marcin
