multicast arp entry

[Eugene Grosbein]

Hi!

route -n monitor shows me:

got message of size 236 on Tue May 18 16:42:26 2004 
RTM_ADD: Add Route: len 236, pid: 0, seq 0, errno 0,
flags:<UP,HOST,DONE,LLINFO,WASCLONED,MULTICAST>
locks:  inits:
sockaddrs: <DST,GATEWAY,IFP,IFA>
 224.0.0.9 1.0.5e.0.0.9 em3:0.7.e9.1f.f1.de 172.20.2.75

After that arp -an shows:
(224.0.0.9) at 01:00:5e:00:00:09 on em3 permanent [ethernet]

Then tcpdump shows that multicast packets with source IP of interface em1
(those must be directed via em1) go out through em3. I run quagga/ripd
(same effect for zebra) on FreeBSD 4.9-STABLE.

How do I find who installs this route?
