Mobile network design

Hi all,

Im working to develop a mobile network with the follow infrastructure

Hosts 3 and 4 will be static point (cabled points) but, hosts 5,6 and 7 must be mobiles (satellite connections). Would be necessary to create an ad-hoc network with this topology really ussing OSPF-MDR, OSPF-MPR or OLSR in all topology or it's possible using normal OSPF witouth produce problem in the network?

Thanks in advance

Quite an unusual subject but interesting as well.

"OSPF does not have a suitable interface type for
a wireless broadcast environment which is characterized by
a multicast-capable transmission medium and where routers
do not necessarily form a full mesh. Moreover, to adapt to
the unpredictable behavior of mobile nodes, OSPF will have
to increase the amount of topology dissemination messages,
leading to a prohibitively high routing overhead when adopted
in MANETs. Consequently, OSPF does not scale well even
for a quite small MANET"

So no, you can´t use pure OSPF.

More over, here an interesting discussion about OSPF-MDR and OLSR comparison. Hope this can help.

Hi Flavio,

thanks a lot for your help. Your link has been very interesting. But unfortunately I couldn't find any related OLSR protocol in Cisco. Could you confirm me that if it's possible to use?

Thanks in advance.
