Free Range Routing on Amazon Linux 2

---

Getting FRR Installed on Amazon Linux

I set this up because I wanted a simple lab to mess around with BGP and IS-IS. I would have used EVE-NG but could not get it to play nice with a bare metal m5 in aws.

1. Create an Amazon Linux 2 instance
2. Use the free_range_routing.sh script for userdata on the instance

Getting Routers to Route

1. On the security group allow inbound tcp port 179 for bgp and ping for testing

2. Disable source/destination checks on the instance/interfaces

3. Add an IP address to the loopback interface in linux

   sudo ip addr add 1.1.1.1/32 dev lo
   

4. Login to frr with vtysh

   service integrated-vtysh-config
   !
   router bgp 65001
    neighbor 172.31.24.201 remote-as 65002
    !
    address-family ipv4 unicast
     network 1.1.1.1/32
    exit-address-family
   !
   end
   !
   write
