To learn the routing protocol, I created an Amazon EC2 instance of a Linux Ubuntu router inside a virtual private cloud (VPC) where I have full control over IP and can open 0.0.0.0/0 in both directions over all protocols (EC2 without a VPC only permits TCP/UDP/ICMP access control). When I run the daemon in verbose mode it is stuck calling home: ubuntu@ip-192-168-44-12:~$ sudo ampr-ripd -d -v -L KZ0FOX@EM89mx Using metric 0 for routes. Using TCP window 840 for routes. Using gateway 192.168.44.1 for direct 44net endpoints via interface eth0. Calling home Waiting for RIPv2 broadcasts... Calling home Calling home Calling home This system is online in the portal as 3.135.62.22 ( ec2-3-135-62-22.us-east-2.compute.amazonaws.com) and subnet 44.76.0.12/32. Setting up a reference implementation like this one may be good for learning the basic premise and ability to test out a configuration with less variables than one may have at home with an ISP. I welcome any constructive comments or suggestions.
