LAB Assignment
Goal: Setup of Mobile IPv6 environment and analysis of mobility protocols.
1st Part (Mobility LAB):
Please set up the mobile network shown in fig. 1, consisting of (a) a Linux router, (b) a Linux Home Agent, (c) a Linux Mobile/Correspondent Node and (d) a Windows Mobile/Correspondent Node, the latter connecting via two WLANs.

2nd Part (Mobility Analysis):
Analyze the communication protocols on Layers 2, 3 and 4 (TCP) in all subnets by
o recording handover events with the network sniffer (ethereal);
o identifying the corresponding protocol handshakes;
o analyzing the principal and temporal protocol behaviour.
Hints
To complete part I proceed as follows:
o All: Install appropriate operating systems (Suse 9.0, WinXP) with full IPv6 support. Configure IPv4 and IPv6 interfaces.
o Router: activate and configure routing (sysctl) router advertisement daemon (radvd).
o Linux MN + HA: Install and activate MIPv6 stack (http://www.mipl.mediapoli.com/software/), see also http://www.tldp.org/HOWTO/Mobile-IPv6-HOWTO/
o Windows MN: Install and activate MIPv6 stack (will be provided),

g0904.mspx#EBAA
o Set up the network as displayed.
To complete part II proceed as follows:
o Install Ethereal (http://www.ethereal.com/) on all nodes.
o Sniffer in the appropriate networks and analyze events.
