Assume a network as depicted below with a home agent (HA), a foreign agent (FA), a mobile host (MH), and a remote host (RH). The dotted box is the home location of MH. Assume MH's home address is 131.5.24.8, HA's address is 131.5.24.1, FA's address is 14.13.16.1 and RH's address is 17.23.34.55.
a) Create the foreign agent advertisement message that FA sends out on the 14.13.16.0/24 network with a sequence of 1672 and a lifetime of 4 hours. Assume FA advertises the three addresses 14.13.16.2, 14.13.16.3 and 14.13.16.4.
b) Assume MH selects 14.13.16.3 as a care-of address. Create the registration request that MH sends to FA, (which in turn relays it to HA).
