In the "idol speculation" category at this time. Just mulling ways to
familiarize myself with Mobile IP
the idea is to use my computer to simulate a roving user who still needs to
get to the internet. here is what I came up with for a test bed:
Internet
|
outside_LAN ( public IP side )
|
firewall
|
| firewall IP = 192.168.1.1/24
|
inside_Lan ( 192.168.1.x/24 )
|
| router ip = 192.168.1.2/24
|
router_1\
| \
\
frame_relay_cloud-----------------------------------------------------------
-------------------Router_4
/ \
|
| / \
router_4 ip = 192.168.4.1`/24
| / \
|
Router_2 router_3
VLAN_4 = 192.168.4.x/24
| |
| Router IP = 192.168.2.1/24 router_3 ip = 192.168.3.1/24
|
|
VLAN_2 = 192.168.2.x/24 VLAN_3 = 192.168.3.x/24
hope the ASCII art survives the groupstudy message mangler :->
In any case, this being done via the magic of a switch, I can easily move my
computer from vlan to vlan just by changing the connection to the
appropriate port.
At least, that's the theory.
Router 1 is the home agent
routers 2,3, and 4 are the foreign agents.
The idea is to simulate a wireless network, in which a user is wandering
from AP to AP, with the particular APs in different subnets, as might be the
case in a hospital or a business occupying multiple floors or multiple
buildings in a campus. If mobile IP works the way it is advertised, the
roving user can still surf the web, no matter which part of the network he
occupies. not changes required on the user station.
I probably won't be able to test this prior to next week. Too many other
things going on right now. Just wanted to offer this as food for thought,
if anyone out there is looking for some study ideas.
