understanding Routing Cisco vs. Linux
Currently, I am creating a simple Linux Router with CQB and Iptables.
The machine I have only has 2 interfaces.
We have the following devices on our network:
1 Cisco Catalyst connecting 16 Class C Networks
1 Cisco Router Routing packets to the inside
The Catalyst uses VLans for our entire network.
It appears that the Catalyst is doing routing for the virtual networks
as it should. But, I am scratching my head over how the Catalyst
handles incoming and outgoing connections.
Traffic seems to flow differently depending on
Do I need to worry about how the VLAN handles packets
when I install the Linux Router ?
Also does the following diagram look like it will work ?
Currently the route is ->
| 22.214.171.124 (Catalyst Routing of Vlans)
I figure that this may work it is my first attempt at using iproute:
[Linux Router] 126.96.36.199 eth0
ip route add 188.8.131.52 dev eth0
ip route add 184.108.40.206 dev eth1
ip route add 220.127.116.11/24 dev eth1
ip route add 18.104.22.168/24 dev eth1
ip route add 22.214.171.124/24 dev eth1
| 126.96.36.199 (Catalyst Internal Routing)
