It’s been a while since I last shared anything! Recently, I have been learning about BGP knowledge and testing. Previously, I used Bird1 to broadcast BGP, but when I tried to peer with my friend, we couldn’t establish a connection (it was strange, but I could connect with IX). So I uninstalled Bird1 and installed FRRouting instead.
FRRouting is a routing suite that comes from Quagga Fork, and its functionality is also very powerful (its commands are similar to Cisco or Quagga).
First, we need to install FRRouting.
sudo apt update -y sudo apt upgrade -y # Install network packages and GPG packages sudo apt install -y curl gnupg2 traceroute
# Import GPG curl -s https://deb.frrouting.org/frr/keys.asc | sudo apt-key add - FRRVER="frr-stable" # Write software sources echo deb https://deb.frrouting.org/frr $(lsb_release -s -c) $FRRVER | sudo tee -a /etc/apt/sources.list.d/frr.list # Install FRRouting sudo apt update -y && sudo apt install -y frr frr-pythontools
Enable IP forwarding
echo " net.ipv4.conf.all.forwarding = 1 net.ipv6.conf.all.disable_ipv6 = 0 net.ipv6.conf.default.disable_ipv6 = 0 net.ipv6.conf.lo.disable_ipv6 = 0 net.ipv6.conf.default.forwarding = 1 net.ipv6.conf.all.forwarding = 1 net.ipv6.conf.all.proxy_ndp = 1 net.ipv6.conf.all.accept_ra = 2 " | sudo tee -a /etc/sysctl.conf sudo sysctl -p
Activate all functions of FRRouting
sudo sed -i "s/=no/=yes/g" /etc/frr/daemons service frr restart
Enter FRRouting interactive CLI
After entering the interactive CLI, you can start configuring by typing “config”.
