Setting diff classes on a single nic dot1q linux

Hi All,

This is a Network setup that requires knowledge and understanding of [url removed, login to view] .

I have a Linux box that is connected to a Cisco switch.

I need to add multiple classes on a single NIC on the linux box.

I'm almost done with the setup, but I'm having a difficult time finishing it.

I can ping the additional classes on the linux box from OTHER boxes, that reside on SAME class.

But, if you ping the server from a different class, it is not pingable.

This is due probabaly to routing/gateway/reverse-routing or something like that.

That's where I need you assistance.

Here is my configuration:

The setup in the Cisco switch is:

3550-FW#show interfaces trunk

Port Mode Encapsulation Status Native vlan

Fa0/3 on [url removed, login to view] trunking 1

Fa0/46 on [url removed, login to view] trunking 1

Port Vlans allowed on trunk

Fa0/3 100,400

Fa0/46 100,200,400

Port Vlans allowed and active in management domain

Fa0/3 100,400

Fa0/46 100,200,400

Port Vlans in spanning tree forwarding state and not pruned

Fa0/3 100,400

Fa0/46 100,200,400

In my setup, we are going to use interface fa0/3 (fa0/46 is working with ESXi 4.1 and works well).

My server (Linux - CentOS) has a one network interface with the following IP setup:

[url removed, login to view]

[url removed, login to view]

[url removed, login to view]

netwmask: [url removed, login to view]

gateway: 6.9.141.1

I need to ADD another class on this NIC:

[url removed, login to view]

[url removed, login to view]

[url removed, login to view]

netwmask: [url removed, login to view]

gateway: 12.10.22.1

Here are the setup of the files:

/etc/sysconfig/network-scripts # less ifcfg-eth0

# Broadcom Corporation NetXtreme BCM5704 Gigabit Ethernet

DEVICE=eth0

# BOOTPROTO=none

# BROADCAST=[url removed, login to view]

HWADDR=00:0b:cd:ce:3e:b5

ONBOOT=yes

ETHTOOL_OPTS="speed 100 duplex full autoneg off"

# NETMASK=[url removed, login to view]

# IPADDR=[url removed, login to view]

# GATEWAY=6.9.141.1

# TYPE=Ethernet

/etc/sysconfig/network-scripts # less [url removed, login to view]

# Broadcom Corporation NetXtreme BCM5704 Gigabit Ethernet

DEVICE=[url removed, login to view]

VLAN=yes

BOOTPROTO=static

ONBOOT=yes

NETMASK=[url removed, login to view]

IPADDR=[url removed, login to view]

GATEWAY=6.9.141.1

/etc/sysconfig/network-scripts # less [url removed, login to view]

# Broadcom Corporation NetXtreme BCM5704 Gigabit Ethernet

DEVICE=[url removed, login to view]

VLAN=yes

BOOTPROTO=static

ONBOOT=yes

#NETMASK=[url removed, login to view]

#IPADDR=[url removed, login to view]

#GATEWAY=6.9.141.1

/etc/sysconfig/network-scripts # less [url removed, login to view]

DEVICE=[url removed, login to view]

VLAN=yes

BOOTPROTO=static

ONBOOT=yes

IPADDR=[url removed, login to view]

NETMASK=[url removed, login to view]

/etc/sysconfig/network-scripts # less [url removed, login to view]

DEVICE=[url removed, login to view]

VLAN=yes

BOOTPROTO=static

ONBOOT=yes

IPADDR=[url removed, login to view]

NETMASK=[url removed, login to view]

/etc/sysconfig/network-scripts # less /etc/iproute2/rt_tables

#

# reserved values

#

255 local

254 main

253 default

0 unspec

#

# local

#

#1 [url removed, login to view]

100 [url removed, login to view]

400 [url removed, login to view]

I'm still not able to reach the vlan 400 if I ping it from OUTSIDE of the vlan.

This is a simple project and should not take more than minutes to an hour (if few attempts to fix are done).

The budget for this project is not going to exceed $50, so if you ask for more, you are just going to be ignored.

Good luck to all and happy bidding.
