That's bad. How do I enable "multicast forwarding", or, in other words, do you know why ripd doesn't do it for be? On the other hand, I've got another machine with very simple configuration: one fxp0 interface, one rl0 and one gif0 and started quagga/ripd. Two points: tcpdump shows that multicasts go out all three interfaces with right source IP and there is no arp entries for 224.0.0.9 and 224.0.0.1. I couldn't find what is the vital difference between these two machines yet (there are so many of them). Eugene
