Yes the RIP broadcasts come over protocol 4 from amprgw.sysnet.ucsd.edu
Here is a network dump of some directed to my gateway:

Hi there
Did I understand correct that the RIP system we use is RIP over the Tunneling ?
Or in other words we need at first to have Tunnel to AMPR Router
and only then the RIP data can pass through ?
Any Info Welcome
Thanks Forward
