Static Routing

Karthik S S — Thu, 18 Sep 2003 06:01:59 GMT

Hi,

We have planned to configure 4 Networks with static routing. The rough network plan is given below,

NW Range - 192.168.1.0, Hosts per N/W - 6

Subnet Mask - 255.255.255.248

Network -1 : 192.168.1.8
Host1 - has two NICs - one for LAN and the other for Routing the other network (Network2).
host1-LAN : 192.168.1.9
host1-External : 10.0.0.1

Network-2 : 192.168.1.16
Host1 - has two NICs - one for LAN and the other for Routing the other network (Network1).
host1-LAN : 192.168.1.17
host1-External : 10.0.0.2
Host2 - has two NICs - one for LAN and the other for Routing the other network (Network3)
host2-LAN : 192.168.1.18
host2-External : 11.0.0.1

Network3 : 192.168.1.24
Host1 - has two NICs - one for LAN and the other for Routing the other network (Network2).
host1-LAN : 192.168.1.25
host1-External : 11.0.0.2
Host2 - has two NICs - one for LAN and the other for Routing the other network (Network4)
host2-LAN : 192.168.1.26
host2-External : 12.0.0.1

Network4 : 192.168.1.32
Host1 - has two NICs - one for LAN and the other for Routing the other network (Network3).
host1-LAN : 192.168.1.33
host1-External : 12.0.0.2

Now please help me in configuring Static Route entries in these routers.

Thanks,
Karthik S S

Funkyness..

Assumptions: LAN = eth0, External = eth1

Network-1
Host 1:
route add default eth1

Network-2
Host 1:
route add default eth0 gw 192.168.1.18
route add -net 192.168.1.8 netmask 255.255.255.248 eth1

Host 2:
route add default eth1
route add -net 192.168.1.8 netmask 255.255.255.248 eth0 gw 192.168.1.16

Network-3
Host 1:
route add default eth1
route add -net 192.168.1.32 netmask 255.255.255.248 eth0 gw 192.168.1.25

Host 2:
route add default eth0 gw 192.168.1.24
route add -net 192.168.1.32 netmask 255.255.255.248 eth1

Network-4
Host 1:
route add default eth1

Or something like that. Simply put..

The end ones (Network1/Network4) don't care, everything is down the external, thus only defaults.

The two middle networks have the default of the larger side of the newtorks, and smaller of the single subnet's of which are the opposite direction.

As a drawing, it's quite ugly ;P lots of over-lapping lines in the middle.

Enjoy ;)
