Re: Assign three/four different subnets to interface E0???
A minor correction to Hritter's post, the addresses specified should be ip addresses and not network addresses.
You can configure secondary ip addresses on all those subnets, on the same router interface.
ip add 192.168.100.254 255.255.255.0
ip add 220.127.116.11 255.255.255.0 secondary
ip add 18.104.22.168 255.255.255.0 secondary
ip add 22.214.171.124 255.255.255.224 secondary
This should do it.
You can include these addresses in your routing protocol, so that they get advertised to other routers. If you plan to use a router on any of these secondary networks, and run EIGRP or OSPF, it wont work, because neighbors are not formed on secondary networks on either protocols.
