Hi Ondrej, here is a problem I am *not able* to solve: my main BIRD operation concerns with the OSPF routing I have with our CisarNet and Hamnet *hamradio* backbones and, mainly, with the 44.x.x.x/8 and 10.x.x.x/8 networks. Now, since I must distribute, by using the RIP2 protocol, *only* the 44.x.x.x/8 prefixes to another 'ham' gateway which is able *only* to understand and manage the RIP2 protocol, how to rule out the 10.0.0.0/8 prefixes from being distributed to it? And since other *spurious* public IP addresses are collected by the OSPF network, how to rule out those from being distributed, too? many thanks gus -- ----==-- _ 73, gustavo i0ojj ---==---(_)__ __ ____ __ --==---/ / _ \/ // /\ \/ / -=====/_/_//_/\_,_/ /_/\_\ A proud member of linux team An advanced CisarNet backbone TCP/IP server in Colleferro/Rome-JN61lr @ir0rm-7.ampr.org linked to Hamnet site at Nuernberg (Germany)
