you'll need to assign an ip to each vif that is in the same subnet as
your hosts in each vlan, and then set that ip (the one on the vif) as
the default gateway of the clients.
ie:
vlan 101
subnet 192.168.101.0 /24
vyatta ip on eth0.101 192.168.101.1 /24
host ips 192.168.101.2-254 /24 gw 192.168.101.1
vlan 102
subnet 192.168.102.0 /24
vyatta ip on eth0.102 192.168.102.1 /24
host ip 192.168.102.2-254 /24 gw 192.168.102.1
vlan 103
subnet 192.168.103.0 /24
vyatta ip on eth0.103 192.168.103.1 /24
host ip 192.168.103.2-254 /24 gw 192.168.103.1
make sense?

Hi,
I have Two cisco Switchs 2950 sw1 & sw2 with a vtp link (802.1q
trunk). sw1 is the vtp server and sw2 is the vtp client.
The two switchs have 3 vlans: Vlan101, Vlan 102 and vlan 103 and the
vlans can't communicate because there is no routing between them.
I decide to use vyatta to implement routing inter-vlans. So I have a
Vyatta VM that i linked to a port of sw1 and i configured this port
as trunk in the sw1 side (switchport mode trunk). I also create 3
vif (sub interface of my vyatta interface eth0), so now i have
eth0.vif101, eth0.vif102 and eth0.vif103.
with this configuration machines on a vlan can't communicate with
machines on an other vlan: what do i have to do on my vyatta to
activate intervlan routing.
Thanks for your help
