[LARTC] point-point eth routing problem

[LARTC] point-point eth routing problem

[Sanjeev Lakshmanan]

Dear Sir,

Thank you for your response.
The goal of my part of the project is to just setup
routing using point-point eth links between 5 systems 
Static routes will suffice.

I am looking at zebra becuase the static routes I
created are not "working". 

I shall detail what I did and tell you the exact
problems I faced:

Each of the systems has 4 eth cards. and 3 of them are
used in the network. the fourth one is just in case we
need to connect it to a router later on..

So i conneated the eth cards with eth crossover cables
via a patch panel for convenience.Pls corect me if I
should have used striaght through cables

Our project requires all the Ip addresses to one
machine to be the same. 

I am using Redhat Linux 7.1

1. I assigned ip addresses to each interface when I
loaded Linux itself. The Ip addresses are like
192.168.x.y/32 No broadcast address on any interface.
Just the inet address. And no gateway or any other
address.

2. I setup neighbours using "ip neigh add..."

3. Set up static routes using "ip route add ..."

4. But ping doesnt seem to work. in some cases I get
"destination host unreachable" and most of the times
there is no message, and I had to kill it (CTRL C.)

5. There is no other device like a switch or a hub
connected to the network. Just the ethernet crossover
cables between the systems via a patch panel for
convenience. Is the problem becoz of the patch panel?

6. But when I connected a switch to the 4th eth card
of each system, ping works just fine. but when i
remove the switch the ping doesnt work and all packets
are lost.

Please let me know if you need any more details to
answer my questions.

Regards,
Sanjeev.
