You can also use ipset in Linux and OpenWrt to filter from the RIP44 announcements. I only
allow Protocol No. 4 from you all.
I have the script; it's a slight modification of the one found on the Firewall Wiki.
It can be set to run with the -x argument after each RIP44 announcement on ampr-ripd.
Let me know and I'll send a TXT file of it.
