Lab Setup

The lab for this chapter consists of vIOS devices to simplify device configuration. We will use the same lab for this and the next chapters. The topology visual is as follows:

Figure 1: Lab topology

The device configuration is as follows:

Device	Management IP	Loopback IP
r1	192.168.2.218	192.168.0.1
r2	192.168.2.219	192.168.0.2
r3	192.168.2.220	192.168.0.3
r5	192.168.2.221	192.168.0.4
r6	192.168.2.222	192.168.0.5

The Ubuntu hosts information is as follows:

Device Name	External Link Eth0	Internal IP Eth1
Client	192.168.2.211	10.0.0.9
Server	192.168.2.212	10.0.0.5

The Linux hosts are tinycore-linux (http://tinycorelinux.net/) migrated from previous versions of VIRL. The default username and password are both ‘cisco’. If we need to change the interface IP and default gateways, they can be done via the following commands:

cisco@Client:~$ sudo ifconfig eth0 192.168.2.211 netmask 255.255.255.0
cisco@Client:~$ sudo route add default gw 192...
