Another nanonet tutorial... - acbaBaz/Nanonet-Tutorial GitHub Wiki

This tutorial is based on nanonet and consist of following steps.

1. Download the image
2. Building a network test
3. Test srv6

• Download virtualbox image from sr6-vbox-GUI, its based on segment-routing.org with GUI interface

• Run command line, type: cd nanonet

• Create a new topology: leafpad example.ntfl

• Setup the topology by save this network into example.ntfl
  A B 1 0.2 100000
A C 1 0.2 100000
B C 1 0.2 100000
  

• Generate the topology: tools/ntfl2topo.sh example.ntfl Test > topos/example.py

• Build the network: ./build topos/example.py Test

• Run the network as root:
  sudo su
sh Test.topo.sh
  

• Enter to node A:
  ip netns exec A bash
  

• Record the loopback interface (lo) ipv6 address of Node A and Node C:
  ip netns exec A ifconfig
inet6 addr: fc00:2:0:1::1/64 Scope:Global
ip netns exec C ifconfig
inet6 addr: fc00:2:0:2::1/64 Scope:Global
  

• Ping the network from A to C:
  ip netns exec A ping6 -I fc00:2:0:1::1 fc00:2:0:2::1
  

• Result:
  PING fc00:2:0:2::1(fc00:2:0:2::1) from fc00:2:0:1::1 : 56 data bytes
64 bytes from fc00:2:0:2::1: icmp_seq=1 ttl=64 time=4.12 ms
64 bytes from fc00:2:0:2::1: icmp_seq=2 ttl=64 time=4.12 ms
64 bytes from fc00:2:0:2::1: icmp_seq=3 ttl=64 time=4.23 ms
