I tried the second patch you sent, but unfortunately it didn't make any difference. One thing strikes me as strange: Why don't I see any of the multicast packets even when the adapter is in promiscous mode? I can only see broadcasts and unicasts to and from my own address. Listening on tr1 (with "tcpdump -nevv -s4000 -x -i tr1") when quagga sends multicasts on tr0 gives me nothing. Neither the packets I know quagga must send since they are received by the Cisco router, nor the multicast packets the Cisco router sends, show up on tr1.
