[44net] rip routes - how often?

How often are the rip routes transmitted? I have read every 5 mins, but ever time I initially set up a gateway it always seems to take a *lot* longer than that to see anything come thru. https://raw.github.com/hessu/rip44d/master/rip44d I have DMZ on my DD-WRT home router pointed to the pc running the rip daemon, 192.168.1.106 My gateway entry is: 174.103.204.106 ifconfig tunl0 up 44.92.21.1 netmask 255.0.0.0 tunl0 Link encap:IPIP Tunnel HWaddr inet addr:44.92.21.1 Mask:255.0.0.0 UP RUNNING NOARP MULTICAST MTU:0 Metric:1 RX packets:1 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:152 (152.0 B) TX bytes:0 (0.0 B) root@test:~# ./rip44d -v found local address: 192.168.1.106 found local address: 127.0.0.1 found local address: 44.92.21.1 opening UDP socket 520... entering main loop, waiting for RIPv2 datagrams Also watching with tcpdump. Perhaps someone could create a tool to verify protocol 4 packets are reaching the daemon? I always though that might be handy... go to a webpage enter your outside address and it sends a protocol 4 packet... or something?
