>Description:
	While running mpd and quagga with ripd && ospfd enabled, ripd shows the following message in the config:
2007/03/29 18:22:28 RIP: rip_read: cannot find interface for packet from 192.168.200.133 port 520
2007/03/29 18:22:40 RIP: rip_read: cannot find interface for packet from 192.168.200.131 port 520

At the same time: 

ng0: flags=88d1<UP,POINTOPOINT,RUNNING,NOARP,SIMPLEX,MULTICAST> mtu 1400
        inet 192.168.200.129 --> 192.168.200.133 netmask 0xffffffff 
ng1: flags=88d1<UP,POINTOPOINT,RUNNING,NOARP,SIMPLEX,MULTICAST> mtu 1500
        inet 192.168.200.129 --> 192.168.200.131 netmask 0xffffffff 

therefore no updates to the kernel routing table done. 
I am absolutely sure it is a bug in quagga.  

>How-To-Repeat:
	1. have mpd and quagga's ripd running at the same time.
	2. have the same or similar ifconfig output.
	3. have your neighbour to send an update via ng interface.
	4. 100% you will have the same message logged.
	
>Fix:

	not known at the time
